*** Welcome to Mr. Machinist (tm) *** Version 1.02 Copyright 1993 by Allan J. Bremer Helpfile Compilation Date = 12-21-93 ENTER index ( F5 Toggles Display Size ) Topics: Dialogs | Editor | Menus | Glossary Registration | Files created drive Mr. Machinist has been developed to be the choice of CNC programmers and machinist who need quick solutions to math problems. It also enables the user to edit G M coded files created manually or by a CAD/CAM program. With Mr. Machinist you can view a Decimal chart while editing or convert millimeters to inches, get a chord, get the length of a hypotenuse, view and edit multiple machine programs, calculate a bolt circle, calculate speeds feeds, and find the area and volume of just about any shape. Do your calculations and assign variables to formulas using the powerful scientific calculator. You can also strike the F1 key for context sensitive help any time and a library of defined terms will be at your finger tips. One major advantage of Mr. Machinist is its ability to continually keep a log file of all the functions you choose. This log file is constantly being updated as you require answers to functions. You may view the answer file by striking 'Ctrl-F1' and you may print the answer file by striking 'Ctrl-P'. This answer file, called MRMSOLVE.TXT, only exists during your current session. The answer file is renamed to MRMSOLVE.BAK upon the startup of the next session. u The full potential of this program can not be conceived with out reading the manual and working with the tutorials. If you have any suggestions or comments please mail your response to the address below or call the support BBS's at (716) 434-1448 or (716)438-0345. Both boards are 24hrs at 14400. z Allan J.

At the top is an input line under the 'Name' designation. You may type in the file name of your choice and then strike 'Enter'. You do have the option of using wild card characters. If you do not know the name of the file you want to edit or the file is in another directory then you have two choices in the method of retrieval. 1) From the file menu select, 'Change Dir'. A directory selection box will appear and you can use the key board or the mouse to highlight your choice, then strike enter or double click with the mouse to get to that directory. Then the 'Change Dir' box will display the files and sub-directories of that particular choice. At that point you can highlight the file name of your choice and strike 'Enter' or double click. 2) If you do not know the name of the file you want to edit then you will have to search for it. If you remember the first few characters of the file name, you could use wild cards to cause the selection box to display only those files that meet your criteria. Example: RA??.* will show you all files that start with RA and have one or two characters after it and any extension or no extension. RAT.TXT RA.DOC RA RA55 help? ENTER Screen More Help on 'Open a File to Edit' ================================== If you type a file name in the input line that does not exist and then strike 'Enter', the editor will create and open an empty file for you by that name. You will notice a down arrow symbol to the right of the input line, this is a history list, a list of names you have already used. You have the option to choose file names from it by highlighting the file and striking enter or double clicking it with your mouse. T Choosing the 'Open' box will load the file you have chosen into a new edit window. { The file list box is the largest box of the file selection dialog box. This box will show you every file that matches up to your specifications in the input line above it. It will also display the child and parent directories of the current directory. (You can further your understanding of the principles of directories and sub-directories by referring to your DOS manual.) There are some helpful functions you can use while your in the file list box. One way to get into the file list box is to strike 'Enter' after you have chosen 'Open' from the 'File' menu. Another way is to click on any file name in the box with your mouse. Your 'Tab' key on the key board will cycle you through the many choices of your file selection box in one direction, while holding down the 'Shift' key and then striking 'Tab' will cycle you through in the other direction. The Page Up and Down keys will let you view more files if there are more than can fit in one windows view port. The arrow keys will cycle you through individually. When your in the file list box you can also type a lower case letter to search for a file name that starts with that letter. If you type a second letter, it will search for the file name with the first letter you typed and the second letter you typed. You can continue this for all file letters or number characters. If you type a capital letter you will search for a directory name in the same manner. At the bottom of the file dialog box is an information panel. This will tell you all of the information of the file that is currently highlighted. 0 For more information, see Editor in the index.

High speed tapping is used widely in the machining industry and it is used with high accuracy. A hole can be bottom tapped within 0.0010 using ridgid tapping. r Simply input the tap size and you will be given the speeds and feeds for the three main categories of materials. n Acceptable tap sizes ==================== 4-40, 5-40, 6-32, 8-32, 10-24, 10-32, 12-24 1/4-20, 1/4-28, 5/16-18, 5/16-24, 3/8-16 3/8-24, 7/16-14, 7/16-20, 1/2-13, 1/2-20 These are some general speeds and feeds for tapping. This information is general and you can differ from these given speeds and feeds. If you are tapping with a machine that can ridgid tap you can increase the speeds and feeds. Rigid tapping is an excellent method of tapping that can be very accurate. You may also want to multiply your feed by .9 for spring loaded taps to achieve some 'give' in the synchronization of the spindle speed and the machine feed. @ S = Speed F = Feed T = Threads Per Inch. ================================================ T = S / F S = TPI x F = S / TPI ================================================ 3.82 R.P.M. = S.F.P.M. x ----- O.D. ================================================ Material Feet Per Minute Lubrication ======== =============== =========== Alum. 90 - 100 Kerosene & Lard Oil Mach. 40 - 60 Compound, Sulfur-base or Kerosene & Paraffin Tool 25 - 35 Sulfur-base or Kerosene and Lard.

A two flute carbide endmill does well in small shaft keyways. After plunging to depth with the finish endmill, travel back to your starting point and then go up one side and down the other taking as little stock as necessary. ENTER Screen Right Triangle A triangle with a 90 degree angle in it. With two known pieces of information, the solution to all other sides and angles can be obtained as long as one of those pieces of information is a side of the triangle. The three angles added up must equal 180 degrees. : When you hold down the 'Alt' key and strike the 'T', the Trig. screen will appear. The best way to cycle through the input lines is to strike 'Enter'. If you happen to put the maximum amount of digits (12) into the input line then you will be automatically cycled into the next input line. When you have your two pieces of information entered you may then hold down the 'Alt' key and strike 'O' for OK or you may strike 'Enter' until you have reached the OK button and then strike 'Enter'. You may also use the up and down arrows to move up and down the dialog box. The 'Tab' key cycles you through the dialog box in one direction. If you hold down the 'Shift' key and then strike 'Tab' you will cycle through the dialog box in the other direction. Y The Perpendicular Line calculation that is given in the answer box is the distance of the line that extends from the intersection of the side opposite and the side adjacent perpendicular to the hypotenuse.

You must know either the height and radius or the radius and the angle. ENTER Screen Number input only! ****************** Only numbers can be input into formula fields. You will also get this error if you left a needed field blank. Strike the F1 key for help while your in the dialog box if you need further information. ENTER Screen Cutting Speeds and Feeds Input Help =================================== Determine the Feet Per Minute from the chart on the left and input the data into the cutting speed input line. Insert the chip load data by referring to the bottom of the chart on the left. Keep in mind that these are very general speeds and feeds. Start slow and work your way up. The three main factors that determine the rate of metal removal are cutting speed, feedrate and depth of cut. First, take into consideration, the depth of cut, then feed rate and then the cutting speed. ] Formula ======= IPT = Inches Per Tooth T = Number of Teeth FPR = Feed Per Revolution RPM x IPT x T Feed Rate = ------------- FPR RPM x IPT x T FPR = ------------- Feed rate ENTER Screen Feet Per Minute Chart (Page Down for More) =========================================== Material HSS Carb. ******** *** ***** Stainless Steel 50 150 Cast Steel 50 150 Cast Iron 75 225 High-Carbon Steel 50 150 Medium-Carbon Steel 75 200 Low_Carbon Steel 125 375 Brass 300 800 Magnesium 600 1000 Aluminum 600 1000 Copper 300 1000 Inches Per Tooth (Page Up for More) Cutter IPT ****** *** Metal Cutting Saws .001 + Form Cutters .002 End Mills ( less than 1/2" ) .001 + End Mills ( more than 1/2" ) .003 Plain Cutters .005 Side Cutters .007 Face Mills .010 ==================================== Use these calculations as a starting point only. ==================================== ENTER Screen Absolute Value of a Real Number =============================== A Positive number equal to the given number. The Absolute Value of +23 and -23 is 23. ENTER Screen Acute Angel =========== An angle that is less than 90 degrees. ENTER Screen Analytical Geometry =================== Cartesian, or coordinate geometry. Positioning that is represented by coordinates. ENTER Screen Angle ===== The measure of inclination of two straight lines to each other. One complete revolution of a radius vector = 360 degrees. 1 degree = 60 minutes 1 minute = 60 seconds i 51 34' 43" ********** 51 degrees, 34 minutes 43 seconds. ENTER Screen Arc Cosine ========== The inverse Cosine. Written as Arc Cos or Cos -1 ENTER Screen Arc Sine ======== The inverse sin. Written as Arc Sine or Sin -1 ENTER Screen Arc Tangent =========== The inverse tangent. Written as Arc Tan or Tan -1 ENTER Screen Archimedes ========== (287-212 B.C.) Born in Syracuse, Sicily. A mechanical inventor who discovered the laws of levers. Most famous for the Archimedes Screw used to raise water. He discovered the first law of hydrostatics. ENTER Screen Boole, George ============= (1815-1864) An English mathematician. He used logic in algebra to describe true or false math statements. This 'Boolean' Algebra is used by logic circuit designers and describes logic states used in todays micro computer circuitry. (Logic gates) ENTER Screen Cartesian Coordinates ===================== A coordinate system that uses two coordinates to locate a point on a plane and measure it's distance from either of two intersecting straight-line axes along a line parallel to the other axis. Named after the French mathematician Descartes. ENTER Screen Chord ===== A straight line that intersects two points on a curve. ENTER Screen Climb Milling ============= Refers to a milling cutter that is 'climbing up the wall' of the cut just like to two gears meshing together. This type of machining is often used for a good surface finish but not when there is a lot of stock to be taken. 3 Conventional milling is the opposite of climb milling and should be used most of the time. Many forces come into play when a milling cutter is doing it's job. A small and long end mill will 'whip' in the bottom of a cut and flex into or away from a wall depending on the type of milling being performed. When a mill cut is going to remove a slug, this type of cut could cause the slug to be 'sucked' into the tool and therefore create a major boo boo! ENTER Screen Congruent Figures ================= Identical figures. When superimposed, they coincide exactly. ENTER Screen Conic ===== The figure formed by the intersection of a plane with a cone. ENTER Screen Conjugate Angles ================ Angles that equal 360 degrees. ENTER Screen Constant ======== An unchanging quantity. ENTER Screen Conventional Milling ==================== Refers to a milling cutter that is feed into the work piece against the cutter rotation. This type of machining is used most of the time. Many forces come into play when a milling cutter is doing it's job. A small and long end mill will whip in the bottom of a cut and flex into or away from a wall depending on the type of milling being performed. When a mill cut is going to remove a slug, this type of cut is preferred because it pushes the slug away from the piece upon removal. ENTER Screen Coordinates =========== Numbers which locate a point. Two numbers can locate a plane and three can locate a point in space. ENTER Screen Coplaner ======== On the same plane. ENTER Screen Cosecant of an Angle ==================== The reciprocal of the sine of an angle. ENTER Screen Cusp ==== A double point on a curve where two tangents fall on.

ENTER Screen Distance between two points =========================== Two coordinates given, X1, Y1 and X2, Y2. ENTER Screen Distributive Law of Algebra =========================== Multiplication can be 'distributed' over addition. Here is this law at work: ************************* (X + 3)(2X +4) = (X + 3)2x + (X + 3)4 = 2x + 6x + 4x + 12 = 2x + 10x + 12 ENTER Screen Ellipse ======= An oval shape where the sum of the distances of two fixed points is a constant. ENTER Screen Epicycloid ========== A curve that is traced by a point on a diameter that rolls on another diameter. ENTER Screen Hypocycloid =========== A curve that is traced by a point on a diameter that rolls on the inside of another diameter. ENTER Screen Three Points on a Circle ======================== You must input the three X and Y coordinates of three points and you will be given the X and Y center locations and the radius of the circle that passes through those three points. A geometrical law says that if three point are in a plane, in this case X and Y, and not in a straight line or under one another, then it's possible to have a circle pass through those three points. n Formula ============================================= (X3 )+(Y3 ) (X2 )+(Y2 ------------------- - ------------------- 2(X3-X1) 2(X2-X1) Y = ---------------------------------------- Y3-Y1 Y2-Y1 ----- - ----- X3-X1 X2-X1 (X3 ) + (Y3-Y1)((Y3+Y1)-2Y) X = ------------------------------- 2(X3-X1) R = Sqrt( (X3-X) + (Y3-Y) ENTER Screen Portion of a Cylinder ===================== A cylinder that is cut at the top or bottom on an angle. If the cylinder was level at both ends then it would be a cylinder, not a portion of a cylinder. A portion of a cylinder has 2 heights, the upper most portion of the angle cut and the lower most portion. Insert these heights as Height1 and Height2. ENTER Screen CNC Suitability =============== CNC's are suitable for one particular part that needs a large number of tool changes or work coordinate changes. Also, CNC's are suitable for large amounts of small parts needing a lot of work on many different profiles and/or holes.

If you like, you can open the same file more than once for reference purposes. If you want to reference some code from another CNC program you can bring the file up into an edit window, resize it and cut and paste from it to your current CNC program. In doing this you could create a type of 'database' for your machine files. Let's say you have a machine file, (CNC program) called K0154.TXT. You could create a file called K0154N.TXT for the 'notes' to this file. In K0154N.TXT you could put the job number, cycle time, tools used, set up notes and what ever you like! Then when it comes time to look at that CNC program you could call up these two files, resize them to a smaller size and look at both of them! When it comes time to save your changes, strike F2 and it's done. You'll know that you have made a change to the edit window when you see a little star '*' just to the right of the lower left edit window. If you strike Alt-X to quit when the star is there (you have not saved your changes) you will be asked if you want to save your changes. At this time you can strike 'Y' for yes or 'N' for no or 'C' for cancel. Whenever you save a file, Mr. Machinist will keep your old one and put a BAK extension to it. Let's say your editing a file called README.TXT and you make a few changes to it and then you save it. You will now have 2 files on your system by that file name but with different extensions, README.BAK and README.TXT. Do remember this though, if you make a save and a README.BAK exist, the old README.BAK file will be replaced by the newer README.BAK file. Please note that README.BAK is used here just as an example! Using a Mouse ============= It's faster for a user to use the keyboard instead of the mouse, but when it comes to resizing and moving windows, the mouse is the preferred method. The left mouse button is the one you'll always use. Just point and shoot! Pick a menu, click the left button and down comes a menu. Chose from the menu and click for results. To move around edit windows, 'drag' the mouse on the edit window heading. Dragging the mouse means to hold down the left mouse button while moving the mouse. When you want to resize the current window, drag the mouse on the lower right corner of the edit window. To highlight a block of data while editing drag the mouse over the text you desire to mark and that text will become highlighted. The editor incorporated into Mr. Machinist can manipulate a file of 65 K or under. That is the limit at this time. If you want to edit a very large file you will have to use a more powerful editor or 'split' your file and then 'paste' it back together. The editor in Mr. Machinist has the capabilities to edit almost all CNC programs. If the CNC program is larger than this limit then maybe you can create a smaller program by using sub-programs. A small CNC program that does a lot is the sign of a good program!!! This editor is a standard editor that uses commands that are universal in most programs. A small book can be created telling you how to be proficient in using an editor but here are some basics. Features ======== Full mouse support Move, resize, overlap, tile, or cascade Open and view several files at once Search and replace text Cut, copy and paste using the clipboard Paste from one file into another Use the editor while you use the math functions View the clipboard contents Restore deleted text Do block operations, large deletes or inserts ENTER Screen Chord, Volume, and Area of a Spherical Sector ============================================= In the input box you must enter the Radius and Height while in the spherical sector menu. While in the spherical 'segment' menu you must enter the height and one other input, either the radius or the chord. The height can not be greater than 2 x Radius! You will then be displayed an answer box giving you the chord, volume, and area of the spherical sector. z A sphere is a closed surface where all points are the same from a given distance. Another simple name for a sphere is a ball. A spherical sector is a section of a 'ball' or sphere that is cut out from the whole part. It consist of a full revolution and not just a segment. A spherical segment is a cut section from the 'ball' or sphere but it is cut at two parallel lines. k Formula (Spherical Sector) ============================ V = Volume, A = Area, C = Chord: V = (2 x pie x Sqr(radius) x height) / 3 A = pie x radius x (2 x height + .5 x chord) C = 2 x Sqrt(height(2 x radius - height)) Formula (Spherical Segment) ============================= V= pie x Sqr(height) x (radius - height / 3) A= 2 x pie x radius x height C= 2 x Sqrt(height(2 x radius - height)) R= (Sqr(chord + 4 x Sqr(height))/(8 x height) ENTER Screen CNC (Computer Numerical Control) ================================ Machines that are controlled by electronic systems, such as computers, that accept numerical data and other alphanumeric instructions. The purpose of almost all CNC machines is to cut metal. Some main CNC machines in use today are for the purpose of milling, turning, drilling, and boring. The most popular CNC machines in use today are the milling and turning centers. ENTER Screen CAD/CAM ======= CAD = Computer Aided Design CADD = Computer Aided Design Drafting CAM = Computer Aided Manufacturing CAD is a computer system that is used to create architectural designs. After a design has been created by the CAD system it can then go to a programmer who makes a program on the computer for the actual machining of the part. This latter process is usually called CAM. ENTER Screen Torus ===== A shape that looks like an anchor ring or a doughnut. If you were to take a ball and orbit it around a center distance, the shape that it would leave is a Torus. There are two radius involved, the radius of the ball that is orbited and the orbit radius. P Formula: ======== Radius1 = The orbiting ball. Radius2 = The orbit radius. Area = 4 x sqr(pi) x Radius2 x Radius1 Volume = 2 x sqr(pi) x Radius2 x Radius1 ENTER Screen CALCULATOR ========== You can use the keyboard or the mouse to operate the calculator. V F4 brings up the calculator at any time and Alt-F3 will close the calculator window. . Left arrow erases the last character typed. The key toggles the number from + to -. on keyboard is the 'Underscore' key ) The C key clears the input line. ENTER Screen Resize and Move Windows ======================= There are two windows that can be resized, the edit window and the help window. All windows can be moved. Learning to resize and move windows at a good pace can really speed up the job of multiple editing and/or viewing multiple formula answers. , Using the mouse is the quickest way to resize and/or move a window. To resize a window using the mouse, 'drag' the mouse on the lower right corner of the window. To 'drag' the mouse means to hold down the left mouse button while you have the mouse cursor positioned on a certain item. As you hold down the left mouse button on the lower right corner, begin to move the mouse around. You will now see that the window resizes from the lower right position. The window will stay at its current position as soon as you take your finger off of the mouse. e To resize a window using the keyboard, you hold down the 'Alt' key and then strike 'W'. This will pop down the 'Window menu'. Strike the 'R' key to resize a window. After striking the 'R' key you can use the arrow keys to resize the window. When you have the window where you want it, strike the 'Enter' key. This will take you out of the resize mode. To move a window using the mouse you drag the mouse on the top heading of the window. The top heading of a window is the wording that is centered on the top line of the current window. To move a window using the keyboard you should hold down the 'Alt' key and then strike the 'W' key and the 'Window menu' will pop down. Then strike the 'M' key and you will be able to move the window using the arrow keys. ENTER Screen Trapezium ========= A four sided figure in which no two sides are parallel. 3 Help on Trapezium input ======================= Let's assume that the longest side of the four sided figure is down. , ( A Trapezium ) H1 H2 H1 = Tall height of the figure. (Right) H2 = Short height of the figure. (Left) L1 = Distance between heights. L2 = Dist. from left edge to left height. L3 = Dist. from rt. edge to rt. height. Formula ======= (H1 + H2) x L1 + (L2 x H2) + (L3 x H1) Area = -------------------------------------- 2 ENTER Screen Calculator ========== Once the calculator window is on screen you will be ready to enter your calculation or formula. You can strike the 'Tab' key to move around the calculator dialog box. Striking the 'Tab' key will take you to the 'Ok' button, once more will take you to the 'Cancel' button and once more will take you back to the input line. If you hold down the 'Shift' key and then strike 'Tab' you will move around in the opposite direction. You can also use the mouse to click on one of these three items and activate them. Once your in the input line you can start to enter your data. When numerical entry is complete you may strike 'Enter' or click on 'Ok' with your mouse or strike 'O' for 'Ok'. , Example: 4+4*87/456*tan(56) then 'Enter'. The order of precedence is at work here. The calculator evaluates the parts of an expression inside the most deeply nested parentheses before anything else. In the example, the tangent of 56 is calculated and then 87/456 is calculated, then the two are multiplied and 4 is added. Upper and lower case input of functions are treated the same. You may also append an O for octal or an H for hex after a number. If you input 55o, your answer will be 45 because 55 in octal is 45. If you input 640H, your answer will be 1600 because 640 in hex is 1600. When you type a hex constant you must be sure to type a number before it. If you type FF for a hex number then you will get an error, but if you type 0ff then you will get 255. ( You may enter assignment statements such as, a:=3, and b:=3, and also c:=sqrt(a*b). Always use a single character as your variable, A to Z. If you use assignment statements within expressions always be sure they are predeclared. Here is an example using the formula for RPM (R) of a spindle: a 12 x F (Feet per Minute) R = -------------------------- Pi x D (Diameter of Endmill) You would enter f:=200 and then strike 'Enter', d:=0.5 and 'Enter', and for the end result, r:=(12*f)/(pi*d). If you were to leave out the parentheses your result would be in error due to the fact that the calculation would divide first and then do its multiplication. Standard Keys ============= Tab = Activate next item Shift-Tab = Activate in opposite direction. F4 = Bring up calculator window Alt-F3 = Close window. (Any time) Esc = Close window. (Any time) Enter = Calculate answer. (Valid input) Calculator Functions ==================== Be sure to inclose functions with more than one character within parentheses. Example: 5*tan(45)*sqrt(7) + = Addition - = Subtraction / = Division * = Multiplicational ^ = Exponentiation O = Octal (Precede Number) H = Hex (Precede Number) Pi = 3.1416.........

ENTER Screen Mouse Settings ============== Using this function can adjust the speed of a double click on your mouse. It can also change the active button from left to right. (For left handed people) ENTER Screen Wire Cut E.D.M. =============== Wire cut E.D.M. is an electrical discharge machine utilizing a numerically controlled movement and a wire electrode to machine a workpiece to a desired contour. The electrode is is a brass or molybdenum that varies in a diametric range of .002 to .014. The workpiece may be of any material as long as it is conductive. Hardness does not adversely affect the E.D.M. process, but the capacity for the workpiece to conduct heat and electricity do. One terminal of the power supply is connected to the electrode and the other to the workpiece. The electrode and workpiece are held in close proximity by the machine, yet they always remain separated by a small gap. The gap is always filled with a circulating dielectric fluid, usually deionized water in wire cut E.D.M., which acts as an insulator. The dielectric also cools the electrode and workpiece and flushes away the eroded metal particles from the surface of the workpiece. When the voltage from the power supply is first applied across the gap the insulating characteristics of the dielectric prevent the current from flowing. An electrical field is established at the shortest distance between the electrode and the workpiece, the conductive particles form a "bridge" in the direction of this field. When the gap is narrowed, the voltage of the electrical field causes the bridge to ionize, an ionized gas channel forms, this is the point at which the current begins to flow. High temperatures and pressures are generated melting and vaporizing a small section of the workpiece. This current continues during the "on time" of the pulse and turns off during the "off time" of the pulse. During the "off time" the voltage drops to zero, so the current ceases, causing the ionized channel to collapse, and heat and pressure dissipate. z This implosion ejects the melted particles into the dielectric, producing a small cavity in the workpiece. The ejected material is solidified into a small hollow sphere and washed away by the flushing action of the dielectric. Although most of the molten metal is carried away from the workpiece, a small amount is resolidified and is commonly referred to as the recast layer. The size of the cavities produced by the process is directly proportional to the amount of current used. A low current produces a fine finish, and a slow cutting speed, and higher currents produce a rougher finish, and faster cutting speeds. ENTER Screen M.D.I. ====== Manual Data Input ENTER Screen Equiangular Hyperbola ===================== Also called a rectangular or equiangular hyperbola whose transverse and conjugate axis are the same in their length. # Standard equation = X ENTER Screen Vise Information ================ One of the most commonly used vises in the machine shop is the 6 inch vise. Many different forces are being dispersed when a vise is tightened. The part you are clamping must be aligned and indicated in. The more time you spend setting and indicating in your vise, the better the end result will be. One common problem with some vises is that after a few uses the movable jaw can become loose and increase in play. In some vises their is an adjusting cap screw in the middle of the back of the movable jaw. By tightening this cap screw you can minimize the amount of play. ENTER Screen File Menu ========= The file menu brings down a menu full of choices that have to do with editing and printing files. This menu also has the change directory function which helps you search certain directories without typing in full file names. v There is also a Dos Shell function within this menu that 'shells' you out to DOS. To 'shell' out means to leave your program temporarily and go into DOS so you can execute other programs. Keep in mind that when you do this, Mr. Machinist still takes up a little memory so do not try to execute a program that uses a lot of memory or you will not be able to execute it. To get back into your program after shelling out type 'EXIT' at the DOS command line. One thing you can also do to make DOS shell easier is to write a small batch file so that when you strike E a batch file called E.BAT executes and gives the command EXIT. The last command in the file menu is the Alt-X command. This command will exit Mr. Machinist. Strike it any time to exit the program. If your editing a file and you have not saved it, the program will ask you to save it before exiting. Sub Topics: A Open New Save Continue Save Done SaveFile E Change Dir Shell Exit Print ENTER Screen The 'New' command will bring up an edit window with no title. At that time you can start editing a new file. If you want to save it you can bring up the file menu and choose 'Save as' or 'Save'. Either way you will be asked to give the file a name because it does not have a name and it needs one. If you try to 'Exit' the program without saving it you will be asked if you want to save it or not. It's always a good idea to save the file your working on about every 5 minutes or so. ENTER Screen Save ==== The 'Save' menu will save a named file to your disk. You will be asked to give the file a name if you try to save an un-named file. You must be editing a file before this can be active. If your editing a file that is already named, the 'Save' command will save the file without showing you a thing. You'll see your hard drive light come on if your saving it to the hard drive or you will see your floppy lights light up. ? The fastest way to save a named file is to strike the F2 key! ENTER Screen Save as [Ctrl]-[K]-[F] ======= Save text in the current window to disk under a new file name. You are asked to which file you would like to save the text. The file may be an existing disk file, or a new file. Once your text is saved, you can continue using the editor on the current edit window. Note that the window title will change to reflect your new file name. 9 This command is disabled until you open an edit window. ENTER Screen Print ===== You will be able to search through a dialog box and choose the file that you would like to print. If you are editing a file or files and you would like to print one of them, then strike 'F8'. ENTER Screen Dos Shell ========= To 'shell' out means to leave your program temporarily and go into DOS so you can execute other programs. Keep in mind that when you do this, Mr. Machinist still takes up a little memory so do not try to execute a program that uses a lot of memory or you will not be able to execute it. To get back into your program after shelling out type 'EXIT' at the DOS command line. One thing you can also do to make DOS shell easier is to write a small batch file so that when you strike 'E' a batch file called E.BAT executes and gives the command EXIT. If you need more information on creating BATCH files you can look into a DOS manual. < (Remember that the library has rows of computer books to!) ENTER Screen Exit ==== If you hold down the 'Alt' key with one finger and strike the 'X' key with another finger...you will exit the program. The only reason that you may not be able to exit is that you may have some active windows on your desk top that you need to close or your editing a file that has been modified and not saved. ENTER Screen Edit Menu ========= The Edit menu gives you six choices that have to do with editing a file. 8 1. Undo - Undeletes the last line deleted or changed. 2. Cut - Removes selected text from file to clipboard. 3. Copy - Copies selected text to clipboard. 4. Paste - Copies text from clipboard to file. 5. Show - Shows context of clipboard. 6. Clear - Removes selected text without going to clipboard. ENTER Screen Windows ======= The Windows menu gives you six window manipulation choices. A 1. Resize/move - Use arrow keys or shift-arrow keys to move or resize. 2. Zoom - F5 will toggle off and on the 'zoom' window function. 3. Next - F6 will toggle between active windows. 4. Close - Alt-F3 will close the current window. 5. Tile - View all edit windows. 6. Cascade - Stacks all edit windows. ENTER Screen Search ====== The Search menu is used to find certain text in a file and this function can also search and replace chosen text with new text. This menu has three functions to choose from. 1. Find - Finds the text of your choice. 2. Replace - Finds text and then replaces it with new text. 3. Search again - Do another search using the same choice. ENTER Screen Circle Menu =========== The Circle menu is filled with math functions that have everything to do with circles. There are seven main functions. 1. Circ. Segment -Find the angle, chord, height, or Radius. 2. Circle Area - Find the surface area of a circle. 3. Circ. Ring - Find the surface area of a circular ring. 4. Circ. Ring Sector Area - Same as 3 but only a section. 5. Circ. Sector Area - Find a circular sector area. Only two inputs needed. 6. Circumference - Find circle circumference. 7. Three Points - Find X and Y center and radius of a circle. ENTER Screen Circ. Segment ============= This function allows a user to find the Chord, Height, Radius, Total Segment Angle, and Arc Length from two knowns. } There are two instances where there can be no solution, knowing just the Chord and Arc Length or the Height and Arc Length. ENTER Screen Circ. Segment ============= This function allows a user to find the Chord, Height, Radius, Total Segment Angle, and Arc Length of a Circular Segment from two knowns. There are two instances where there is no solution available, knowing just the Chord and Arc Length or the Height and Arc Length. g The first step is to input the two known pieces of information. Certain types of input are not feasible. Take for example a Height input that is greater than or equal to the Radius. If the Height is greater than the Radius, subtract the Radius from the Height. Another example of improper input is a Chord that is greater than the Diameter of the Circle. Remember that your answers not only go to a dialog box but also to a file that exists on your hard drive called MRMSOLVE.TXT. This file can be viewed or printed at any time. ENTER Screen Circle Area =========== This choice simply finds the area of a given circle diameter. G Input the Diameter of the Circle you would like to find the Area for. Area = Pie x Radius Squared ENTER Screen Circular Ring Area ================== This function will find the Area of a Circular Ring. Input the Outside Diameter and then the Inside Diameter. Area = Pie x (OD - ID ENTER Screen Circular Ring Sector Area ========================= This function is able to give you the Area of the Sector of a Circular Ring. You need to know three things: the Angle of the Sector, the OD and the ID. Area of a Circular Ring Sector Formula ====================================== ( OR = Outer Radius, IR = Inner Radius ) ((Sector Angle x Pie) / 360)) x (OR - IR ENTER Screen Circular Sector Area ==================== This function gives you a choice of entering the two knowns and then calculates the answer. You may either enter the Radius and Angle, Radius and Arc Length, Radius and Area, Angle and Arc Length, Angle and Area, or Area and Arc Length...any combination is possible! ENTER Screen Circumference of a Circle ========================= This function will find the Circumference of a Circle. The circumference of a circle is the total length of a circle, as if you were to 'cut' the circular line and lay it flat and then measure it. ! Circumference = Pie x Diameter ENTER Screen Three Points on a Circle ======================== A geometrical law says that if three point are in a plane, in this case X and Y, and not in a straight line or under one another, then it's possible to have a circle pass through those three points. Keep in mind that you can cause an error and you'll have to reboot your computer if you input your coordinates as a straight line. You will also find X and Y coordinates and radiuses of large amounts if you input three points that are almost a straight line. n Formula ============================================= (X3 )+(Y3 ) (X2 )+(Y2 ------------------- - ------------------- 2(X3-X1) 2(X2-X1) Y = ---------------------------------------- Y3-Y1 Y2-Y1 ----- - ----- X3-X1 X2-X1 (X3 ) + (Y3-Y1)((Y3+Y1)-2Y) X = ------------------------------- 2(X3-X1) R = Sqrt( (X3-X) + (Y3-Y) ENTER Screen Math Menu ========= The Math menu has nine functions to do with math. 1. Trig. - Right angle trig. (Give the two knowns) 2.

Between Two Points - Give two X and Y's. 7. Middle of Two Points - Give two X and Y's. 8. Three Points Shift/Rotate - Give three X and Y's and new X and Y origins and the degree of rotation, (if any). 9. Calculator - Do formulas and calculations. ENTER Screen Trigonometry Screen =================== Choosing this function will give you a screen that will ask you for the two knowns of a right triangle. The function will then give you all the angles and side dimensions of that right triangle and also the perimeter, inner circle diameter, outer circle diameter, and perpendicular line that has to do with that particular right triangle. ENTER Screen Polar Coordinates ================= This function will ask you for a radius and an angle and then it will give you the X and Y coordinate of the point where that angle line meets that radius circle from center X/Y zero. ENTER Screen Distance Across Square Corners ============================== This function will ask you for the height of the square and then it will give you the distance from corner to corner. ENTER Screen Distance Across Hex Corners =========================== This function will ask you for the height of the hex from top to bottom, (From flat to flat) and then give you the distance across hex corners. ENTER Screen Distance Between 2 Points ========================= This function will ask you for two X and Y coordinates and then give you the distance between these two points. ENTER Screen Middle of 2 Points ================== This function will ask you for the two X and Y coordinate locations. You will then be shown the X and Y coordinate of the point that lies exactly in the middle. ENTER Screen Three Points Shifted and Rotated ================================ This function will ask you to input three X and Y coordinates, a shift location, and a rotation angle. The X and Y Datum position is what is being shifted here or in other words the reference or datum point. d The rotation begins at the 3 O'clock position and swings around in a counter clock wise direction.

You'll probably have to press it twice to get to the previous page. Thereafter, it works as a true page up feature. ENTER Screen Document Reform [Ctrl]-[Q]-[U] FORMAT =============== Quickly reformat your document text. A dialog box will appear that allows you to select whether to begin reformatting at the current cursor position or from the beginning of the document. Reformatting is based on the position of the first character in the first line of a paragraph and the current right margin setting. You must be VERY careful when using this feature for you can easily ruin your document's appearance using the reformatting feature. You can NOT undo the reformatting process. It is permanent. Therefore, you are advised to save your document BEFORE you use this feature. 9 This command is disabled until you open an edit window. ENTER Screen Paragraph Reform [Ctrl]-[B] FORMAT ================ Quickly reformat a paragraph. Reformatting is based on the position of the first character of the current line the cursor is on and the current right margin setting. Reformatting takes place from the current line to the end of the paragraph. > You can NOT undo the reformatting process. It is permanent. 9 This command is disabled until you open an edit window. ENTER Screen Right Margin [Ctrl]-[O]-[R] EDITOR ============ Set a right margin value for the editor. A dialog box will appear that asks you to enter a right margin value. Right margin values may range from 10 to 255. The default right margin is 76. The right margin is used by the editor wordwrap, reformatting, and centering features to determine where to wrap a line of text. 9 This command is disabled until you open an edit window. ENTER Screen Scroll Down [Ctrl]-[Z] CURSOR =========== EDITOR Scrolls the screen up while maintaining the cursor position. If the original cursor position scrolls off the screen, the cursor scrolls down a line. This forces the cursor to stay in the upper left corner of the screen should the original cursor position scroll away. ENTER Screen Scroll Up [Ctrl]-[W] CURSOR ========= EDITOR Scrolls the screen down while maintaining the cursor position. If the original cursor position scrolls off the screen, the cursor scrolls up a line. This forces the cursor to stay in the lower left corner of the screen should the original cursor position scroll away. ENTER Screen Select Word [Ctrl]-[K]-[T] EDITOR =========== SELECT Highlight the current word the cursor is sitting on. The word is marked from the current cursor position to the next space or end of line, whichever comes first. The marked word is put into the clipboard without further effort on your part. Marking works in the normal manner, i.e., it disappears the moment you move the cursor. z Note that NOTHING will happen if you try to use this command when the cursor is sitting on a space or the end of a line. ENTER Screen Tab Stops [Ctrl]-[O]-[I] TAB ========= Enter custom tab stop preferences in a dialog box. These tab stops are used to allow you to quickly insert spaces, or jump over text to a designated tab stop. 9 This command is disabled until you open an edit window. ENTER Screen Start Select [Ctrl]-[K]-[B] EDITOR ============ [Shift]-[Down Arrow] SELECT Start selecting text. Selected text is that text which is not the same color as normal text. You select text when you want to perform a particular action on that text and no other text, such as COPY, CUT, CLEAR, etc. ENTER Screen Tab Key [Tab] EDITOR ======= [Ctrl]-[I] TAB Move the cursor to the next tab stop. Tab stops default to every fifth character on a line. You may reset the tab stops by using [Ctrl]-[O]-[I]. x When in INSERT mode, the cursor will attempt to go to the next tab stop, happily INSERTING SPACES as it looks for that next stopping point. If it is at the last tab stop, it stops inserting spaces and takes a big jump to the first character of the next line. Try to keep tab use to a minimum when the cursor is in insert mode. You eat up valuable buffer space real quick! 7 When in OVERSTRIKE mode, the cursor will attempt to go to the next tab stop, happily skipping over characters as it looks for that next stopping point. If it is at the last tab stop, OR the line is too short to allow it to reach the next tab stop, it takes a big jump to the first character of the next line. ENTER Screen Document End [Ctrl]-[PgDn] CURSOR ============ [Ctrl]-[Q]-[C] EDITOR Move the cursor from its current position to the end of the document. ENTER Screen Document Start [Ctrl]-[PgUp] CURSOR ============== [Ctrl]-[Q]-[R] EDITOR Move the cursor from its current position to the start of the document. ENTER Screen Word Left [Ctrl]-[F] CURSOR ========= [Ctrl]-[Right-Arrow] EDITOR Move the cursor to the beginning of the previous word. Use this feature when you want to quickly jump from word to word. ENTER Screen Word Right [Ctrl]-[A] CURSOR ========== [Ctrl]-[Left Arrow] EDITOR Move the cursor to the beginning of the next word. Use this feature when you want to quickly jump from word to word. ENTER Screen Wordwrap [Ctrl]-[O]-[W] EDITOR ======== Toggle the editor wordwrap feature on/off. Wordwrap allows you to type in text and automatically wrap to the next line when the cursor reaches the current right margin setting. I If wordwrap is on, a "W" will appear on the edit window indicator line. 9 This command is disabled until you open an edit window. ENTER Screen Goto Marker [Ctrl]-[Q]-[#] CURSOR =========== MARK Using the WordStar [Ctrl]-[Q]-[#] key sequence, where "#" is a number 1,2,3,4,5,6,7,8,9, or 0, will allow you to access up to 10 place markers you have previously set in your text. Your cursor will go nowhere if you try to jump to a non-existent marker. Hold down the 'Ctrl' key and then strike 'q', let up on both keys and then strike a previously set number key and if this number key has been set you will go to the marked line #. 9 This command is disabled until you open an edit window. ENTER Screen Set Marker [Ctrl]-[K]-[#] MARK ========== Using the WordStar [Ctrl]-[K]-[#] key sequence, where "#" is a number 1,2,3,4,5,6,7,8,9, or 0, will allow you to set up to 10 place markers in your text. While holding down the 'Ctrl' key strike 'k', then let up on both keys and strike a number key. Nothing will appear to have happened but in actuality you have set a place marker to the number key you have struck. 9 This command is disabled until you open an edit window.

MRMSOLVE.TXT ============ This is a file that is created and deleted each time the program is executed. It holds all of the answers to each function except drill speeds and feeds and bolt circle calculations. This file can be viewed and printed at any time. Holding down the 'Ctrl' key and then striking 'F1' will let you view this file and holding down the 'Ctrl' key and then striking 'P' will print this file. MRMDRILL.TXT ============ This is a file that is created only when you choose the drill speed and feed function. It holds all of the answers to the drill speed and feed calculations. This file can be viewed and printed at any time. Holding down the 'Ctrl' key and then striking 'F4' will let you view this file and holding down the 'Ctrl' key and then striking 'T' will print this file. MRMBOLT.TXT ============ This is a file that is created only when you choose the bolt circle calculation function. It holds all of the answers to the bolt circle calculations. This file can be viewed and printed at any time. Holding down the 'Ctrl' key and then striking 'F8' will let you view this file and holding down the 'Ctrl' key and then striking 'F9' will print this file. =============================================================== o All of these files get deleted or 'cleaned up' after you exit the program. If you would like to save these files in order to edit them later or have them available for information then you must rename them before you exit the program. You would do this by bringing them up in the editor and choosing the 'Save As' function. If for some reason the files do exist on your drive when you first execute MRM (Mr. Machinist) the program will detect this and ask you if you want to delete them or leave them alone. If you do not delete them then the new information will be appended or 'added' to the already existing files. ENTER Screen Equiangular Spiral ================== A Spiral is a curve that twists around a fixed position. For any point on this type of spiral, the angle between a tangent line and the line to its origin is the same. ENTER Screen Escribed Circle of a Triangle ============================= A Circle that is tangent to the side of a triangle and to the other two sides that are extended. ENTER Screen Exponent ======== ----> This means 5 x 5. The exponent is the number of times the base number is multiplied by. In this case, 2 is the exponent. ENTER Screen Factor ====== The factor of an integer is also called the divisor of an integer. 45 is a factor of 3510 because 45 * 78 = 3510. To test if an integer is a factor of another integer you divide the integers and then check an see if there is a remainder. If there is a remainder of 0 then the integer is a factor of the other integer. ENTER Screen Broaching ========= A type of process used in forming symmetrical or irregular, grooves, or slots in machined parts. The broaching process is rapid, accurate and also leaves a good finish. Broaching is usually used to cut keyways, machine round holes to square, hexagonal, or other shapes, forming splined holes, and for a lot of internal operations. Z These types of tools are usually long shanked and taper to the finished size at the top. ENTER Screen Backup Files ============ Using this option you can choose to create or not to create backup files. Backup files are created with the file extension .BAK by default. M When you edit a file that exists on your drive, that file is actually in two places: On your disk or drive, and in the RAM of your computer. When you first create a file, it only exists in RAM until you save it to disk. When you save a file to disk or drive for the first time it exists with the name that you chose to give it. Mr. Machinist will create a backup file by default when you save a file that already exists on your disk or drive. You can choose to shut this feature off therefore saving on disk space but loosing the chance to have a file that has not been over written. ENTER Screen Random Access Memory. A memory consisting of a variable number of RAM chips providing access to any storage location point by means of horizontal and vertical co-ordinates. Information may be written into or taken from RAM very rapidly, under computer control. RAM may be dynamic, i.e. the contents may have to be regularly rewritten (refreshed), or it may be static, in which case the storage cell is a flip-flop element, in one or two stable and electrically alterable states.

ENTER Screen Remove Sequence Numbers Insert Sequence Numbers Split Large Files N Sequence Numbers ================== A sequence number is usually the first word that appears in a block or sentence of a text file for CNC machines. There are two main reasons behind a sequence number. K 1) Lets the operator know which line the machine is currently processing. E 2) Provides the operator a way to search or find a particular line. These sequence numbers usually go to four digits and begin with an N. The very first line of a CNC program or 'text file' always begins with an O on the CNC machine but not always in a file on a personal computer. B Here is an example of a G and M code file with sequence numbers: :0203 (05-07-93) N0005 (ARM-ROCKER) N0010 (123456 JOB#1234) N0015 G00 G17 G40 G49 G80 N0020 G30 G91 Z0 N0025 T01M6 N0030 (.625 EMILL) N0035 G55 G90 G00 X-.65 Y0.0 N0040 S1800 M03 N0045 G43 Z1. H12 N0050 M08 N0055 Z.1 N0060 G01 Z-.031 F20.0 N0065 X.65 F5.0 etc, etc,. ENTER Screen Remove Sequence Numbers Insert Sequence Numbers Split Large Files Clear Your CNC's Memory ======================= Some machine shops have to download there CNC files to a personal computer in an office some where. Many shops now are supplying there workers with computers right on there bench near there machine. As a CNC's control gets filled with programs it can become full and cause the operator to have to download one or more programs to make memory enough for the current program to load. Many CNC controls offer a function that lets them download ALL files in the CNC's memory to ONE file on the personal computer. This is the fastest method of clearing the CNC memory. There is just one big problem that people face when they have this huge file on there computer with many programs all in one file! They have to manually cut and paste to get even one program back to the CNC. d Mr. Machinist has a one of a kind function in it that can 'split' a large file that has been downloaded from a CNC. The purpose of this function is to rewrite ALL of the individual programs to seperate files on the personal computer and they are named by there four digit program number just as they were on the CNC with an additional extension of .TXT. ENTER Screen Remove Sequence Numbers Insert Sequence Numbers Split ===== The main purpose of this function is to 'split' a large text file that was downloaded to a personal computer by a CNC machine into all of the original seperate programs. You would have to manually cut and paste using an editor to do this if you did not have this function to work with and that would take a lot of time and money! Mr. Machinist will ask you for the file name of the large text file and then it will look for the first occurance of a line that starts with a ':'. Once it finds the colon Mr. Machinist will get the next four digits and add an extension of .TXT to it and give the new file the proper program number. It will then begin to copy every line after the colon to the new file until it reaches a blank line. Once a blank line is encountered the program will look for the next occurance of a ':' which should be the next line. At that time the same process occurs until every file is written to the specified directory. If the file name should exist in the directory already then a message box will appear letting you know that the file does exist. This information will also be sent to the MRMSOLVE.TXT answer file. You will have to delete the file that exist in order to rewrite it. z After this process is complete, the original large file will still remain for you to decide what you want to do with it. % One little note: ================ A good CNC programmer should know a lot about DOS. Read manuals carefully and study to show thyself approved! ENTER Screen Insert Sequence Numbers Split Large Files N Sequence Number Removal ========================= The Mr. Machinist program has a function in it that can remove N sequence numbers from a CNC text file on your computer. You will be asked for the name of the directory and file that you want the N numbers removed from and the new file name. If the new file exists on your drive you will be shown an error box and then you will start the process over. If the new file name is the same as the old file name you will be prompted to verify the write over procedure. It is advisable to give the file name a different name so you can view the way it was un-sequenced and not be afraid of loosing the old one. l The removal function will un-sequence every line except lines that do not have N sequence numbers in them. ENTER Screen Remove Sequence Numbers Split Large Files N Sequence Number Insertion =========================== The Mr. Machinist program has a function in it that can insert N sequence numbers into an un-sequenced G and M code file on the personal computer. If there are already scrambled sequence numbers in the file it would be wise to remove the sequence numbers using the remove function and then re-sequence the file using this function. Q To Insert Sequence Numbers into a File ====================================== You will be displayed the file dialog box and you will be in the file name input line. Input the file name to sequence. For more help on choosing sequence tap your 'Tab' key and then strike 'Enter'. ENTER Screen Remove Sequence Numbers Insert Sequence Numbers Split Large Files Choose a file to sequence ========================= This will open a file selection dialog box that will display all the files in your current directory. At the top is an input line under the 'Name' designation. You may type in the file name of your choice and then strike 'Enter'. You do have the option of using wild card characters. If you do not know the name of the file you want to sequence or the file is in another directory then you have two choices in the method of retrieval. 1) From the file menu select, 'Change Dir'. A directory selection box will appear and you can use the key board or the mouse to highlight your choice, then strike enter or double click with the mouse to get to that directory. Then the 'Change Dir' box will display the files and sub-directories of that particular choice. At that point you can highlight the file name of your choice and strike 'Enter' or double click. 2) If you do not know the name of the file you want to sequence then you will have to search for it. If you remember the first few characters of the file name, you could use wild cards to cause the selection box to display only those files that meet your criteria. Example: 03??.* will show you all files that start with RA and have one or two characters after it and any extension or no extension. 03T.TXT 03.DOC 0355.TXT help? ENTER Screen Remove Sequence Numbers Insert Sequence Numbers Split Large Files More Help on 'Choose a File to Sequence' ======================================== If you type a file name in the input line that does not exist and then strike 'Enter', the editor will create and open an empty file for you by that name. You will notice a down arrow symbol to the right of the input line, this is a history list, a list of names you have already used. You have the option to choose file names from it by highlighting the file and striking enter or double clicking it with your mouse. If you wanted to begin to manually create a CNC program then you would start this way. T Choosing the 'Open' box will load the file you have chosen into a new edit window. { The file list box is the largest box of the file selection dialog box. This box will show you every file that matches up to your specifications in the input line above it. It will also display the child and parent directories of the current directory. (You can further your understanding of the principles of directories and sub-directories by referring to your DOS manual.) There are some helpful functions you can use while your in the file list box. One way to get into the file list box is to strike 'Enter' after you have chosen 'Open' from the 'File' menu. Another way is to click on any file name in the box with your mouse. Your 'Tab' key on the key board will cycle you through the many choices of your file selection box in one direction, while holding down the 'Shift' key and then striking 'Tab' will cycle you through in the other direction. The Page Up and Down keys will let you view more files if there are more than can fit in one windows view port. The arrow keys will cycle you through individually. When your in the file list box you can also type a lower case letter to search for a file name that starts with that letter. If you type a second letter, it will search for the file name with the first letter you typed and the second letter you typed. You can continue this for all file letters or number characters. If you type a capital letter you will search for a directory name in the same manner. At the bottom of the file dialog box is an information panel. This will tell you all of the information of the file that is currently highlighted.
