------------------------ CIMplicity User's Manual ------------------------ Copyright 1991, PMX Inc. First printing, Apr 1991 CIMplicity is an introductory level CIM (Integrated CAD/CAM) system. Al- though it is powerful, is just a subset of the larger packages available from us. It is offered as a starter system for those that are new to the CAD/CAM field. Its CAD capabilities are fine for making simple mechan- ical drawings, doing design work, and for driving a plotter to generate finished plans. Its CAM capabilities include feature based machining of finish toolpaths and drilling cycles, and for generating NC/CNC machine tapes for the Fanuc/Yasnac/Okuma style of controls. It does NOT include any roughing cycles, island avoidance, curves, advanced patterns, or for sophisticated control of the output. However, it is a very usable CAD/ CAM system. Customer Support: ----------------- In order to make CIMplicity available to everyone that needs it, a lim- ited customer support plan is available. Please do NOT attempt to call in for support. Do NOT ask us to provide extensive problem analysis. When you need to have a question (or questions) answered, or a problem solved, please narrow it down to a point where we can reproduce it immediately. If necessary, send us a 5-1/4 floppy disk with the part- program (and related) files. Explain the problem on a sketch or screen- print of the part. If we cannot duplicate the situation in a couple of minutes, your request will be returned with a notice that you must further isolate the problem before we can help you. When you send in the request, include your serial number and authorization code, and you MUST enclose a self-addressed stamped envelope. If you want your floppy disk returned, the envelope must be large enough to hold it and it must have sufficient postage.

Learning to Use CIMplicity: --------------------------- This manual is by no means a complete technical reference. Instead, we recommend that you refer to the on-line help for detailed questions. This is always available in CIMplicity by pointing at the command in question and hitting the [F10] key. This manual serves two purposes: 1) It answers some of the more common questions. 2) It serves as a tutorial to introduce you to the system. We feel that CIMplicity is easy enough to use that you will not need an extensive manual. However, we DO recommend that you begin by following along with the tutorials that follow. After that, experimentation is the best way to learn. Here are a few definitions: 1. LAYER: A LAYER is a concept used in CAD/CAM systems that is roughly the equivalent of a transparency on a draftsman's drawing. In other words, you may draw the part on layer 0, label a pocket by drawing it in another color on layer 1, show the machining toolpath on layer 2, then put the dimensions on layer 250. 2. MASK: A MASK is a method of helping you select specific items from the screen. For instance, you may only wish to delete arcs, and only those that are on layer 12. This is called "masking". Try not to confuse a layer mask with the layer number. For example, you may draw a line on layer 3 (the layer number) and then delete a circle on layer 5. (the layer mask) 3. GROUP: A GROUP is what we call a feature, such as the pocket in the example above. A group is a set of lines, arcs, and circles that duplicates lines, arcs, and circles on another layer, but in a different color, in order to highlight a feature such as HOLES, an OUTLINE, or POCKET. Every time you build a new group, CIMplicity will place it on the lowest vacant layer. Thus, when a group is labelled "POCKET-3", it means that this group is a POCKET that is drawn on layer number 3. 4. POST: A post-processor is a program that customizes the output to drive a specific NC/CNC machine. Two posts are provided with CIMplicity: FLATHE and FMILL, which are generic lathe and mill posts for the most common NC/CNC machines. The output of a post is called a TAPE, even though it is normally stored as a file on disk. 5. COMMAND, OPERATION, FUNCTION, and INFO: A COMMAND is an instruction to CIMplicity to do something, usually invoked by selections from the main menu. An OPERATION is a command that is unique to the current CAD/CAM mode, such as FINISH MACHINE, CROSSHATCH, or DIMENSION. A FUNCTION is a mathematic/trigonometric instruction such as TAN, COS, SIN, or SQR. Finally, the INFO values are items that appear in the info table, such as COLOR, TOOLNO, or FEEDRATE. Quick Reference Sheets: ----------------------- Accelerator keys: [F1] Mini-INFO table for setting various modes, flags, and defaults. [F2] Sets "Endpoint" pick mode for one pick only.

Digitize selectors (when the cursor is shaped like a "+" crosshair) [F2] Digitize only at an endpoint. [F3] Digitize only at a center-point. [F4] Digitize only at an intersection of two geometry items. Where to pick: FILLET Pick the portions of the legs to be retained after filleting. CHAMFER Pick the portions of the legs to be retained after chamfering. TRIM BOTH Pick the portions of the legs to be retained after trimming. TRIM MODAL Pick the portions of the legs to be discarded after trimming. CHAIN START Pick the endpoint of the item where you wish the chain to start. NEXT MOVE Pick on an item that emanates from the center of the bullseye. DRILL w/SORT Pick the first hole to be drilled. Five steps of part-programming: 1. SETUP Start the part, enter a description, load a setup file. 2. GEOMETRY Build the construction geometry, trim it up as the final part. 3. GROUPING Label the features that are to be machined. 4. OPERATIONS Perform the necessary operations to complete the part. 5. PROCESS Build the NC/CNC tape.

Save the part-program pick SAVE PART FIRST Drawing Example: ---------------- In this example, we will start from an existing drawing generated as a DXF file, load it in, then dimension it. The DXF file that is provided has points (marked with an "X") in it to help you locate the positions noted below. However, the DXF files that you normally load will not contain such points, just the lines, arcs, text, and circles. C I J A ************************* H * N *** * ** * * B M L * * * * * * * * D * ****************** * F * * * K * * * * * * ****************************************************** G E Refer to the drawing above for the pick points mentioned in the tutorial. Remember: If you make an error, hit the [Alt]-[U] keys to UNDO that command. STEP 1: Start the part-program, describe it, load a setup file, and select DIAMETER programming. (If the part-program named D-TEST1 already exists, use a different name.) [ ] 1a. Start up CIMplicity CIM [ ] 1b. Give the part a name D-TEST1 [ ] 1c.

Load all layers [Enter] (button 1) STEP 3: (Since we are NOT going to machine this part, we can skip this step.) STEP 4: Perform the necessary operations. In several of these operations, you are told to hit the [F2] key before picking. This causes the system to select the nearest geometry item endpoint, making a much more precise drawing. (Remember: to "pick" always means to use button 1.) [ ] 4a. Invoke HORIZONTAL DIMENSION OPER: DIMENSION: HORIZONTAL [ ] 4b. Select the points to be measured [F2] pick A, then [F2] pick B [ ] 4c.

Pick the start point pick near A [ ] 4y. Pick the next move pick near N [ ] 4z. Terminate the command [Ins] (button 2) STEP 5: [ ] 5a. Exit from CIMplicity FILES: EXIT [ ] 5b. Save the part-program pick SAVE PART FIRST Pointers: --------- 1. If you wish to alter a feedrate on a toolpath or a portion of it, or you want to change a color or other INFO TABLE value, use the INFO: ALTER GEOM INFO command in the INFO menu. (Do not confuse the INFO menu with the INFO TABLE. The INFO MENU contins commands that may be used to manipulate the values in the INFO TABLE.) 2. You may edit toolpath geometry, move it, add new geometry to it, fillet it, or copy it. However, if you do so, you must supply CIMplicity with enough information that it can properly place the edited information into a desirable cutting sequence. For instance, if you add an arc to a toolpath by describing its endpoints and mid- point, CIMplicity will come back and machine the arc AFTER the rest of the toolpath. However, if you added the arc by using the FILLET command, CIMplicity would sequence the machining of the arc so that it would occur between the two items filleted. Note that in order to add geometry to a toolpath, you must set the layer number to the same layer on which the toolpath resides. 3. Let CIMplicity perform all of your cutter compensation. It does a better job than the NC/CNC machines, and it allows you to visually check the toolpath on the computer. Go ahead and turn on the CDC on the NC/CNC machine, but set the CDC registers to an offset of 0.0 so that no machine compensation is done. In that way you can still correct for wear and tool fluctuation by changing value in the register. 4. When you use the COPY command for multiple-fixtured parts, CIMplicity automatically tool-sorts. This means that it will machine all of the parts using the first tool before switching to the second tool, and so forth. 5. If you think that CIMplicity does something in a different manner than you would like, it may be that you have a selection in the INFO TABLE set incorrectly. Inspect the values in the table closely when you perform a machining operation. Note: always set info values from top-to-bottom, as some values affect values below them in the table. 6. You cannot change Z-levels with the INFO: ALTER GEOM INFO command! The INFO menu does NOT change any coordinate values. Instead, use the EDIT menu, as its purpose IS to change coordinate values. 7. To stretch one end of a Z-only (third axis) line such as a mill- plunge, set the Z to that level using [Alt]-[Z], hit [F1] and set the TYPE MASK to 3D (Z) LEVEL, then invoke the STRETCH command. (Remember to clear the TYPE MASK when you are done.) 8. If you bring in geometry from another CAD system via DXF, or CADL; it will often contain gaps, overlaps, and redundant geometry. Use the EDIT: TRIM/BREAK: CONTINUITY TRIM command to clean up such geometry before grouping it. 9. An operation named MANUAL PATH is available in the CONTOUR mode, which allows you to program in a G-code style. A value in the info table, MANUAL G, can be set to 92, 0, 1, 2, 3, 81, or 83; then X,Y,Z positions along the contour can be entered. This allows you to do manual programming, yet retain machine independence, and to make use of the mathematical and geometric capabilities of CIMplicity. 10. Commands may be nested when using CIMplicity. In other words, when you are in the middle of building an arc, you may decide to first trim a line (using the [Alt]-[X] key); then while performing the trim, zoom in on the part (using the [Alt]-[W] command), then resume with the arc definition. If you do this, then perform an UNDO, the entire set of nested operations will be undone. 11. In case you didn't notice: CIMplicity supports multiple UNDOs; the use of mathematical expressions, variables, and algebraic functions; and graphic part-preview (to see this, first use the [Ins] key for a directory when loading a part). Many of the questions we get, could have be answered by consulting the HELP [F10] within CIMplicity. Please get used to using the [F10] key frequently. Questions We Often Hear: ------------------------ Q: How can I get the output to more closely resemble the tapes that I need to drive my NC/CNC machine? A: You must purchase a post-processor (they start at about $1000) or have access to a post-processor development kit to write your own. -------------------------------------------------------------------------- Q: What is this NC/BASIC language? A: NC/BASIC is a language that may be used to write your own post-processors, or to write family-of-parts programs, or to add your own commands to the CAD/CAM system. For instance, you may write this program named BOX: MENU N, "SQUARE", "RECTANGULAR" IF N = 1 GOSUB MKSQUARE ELSE GOSUB MKRECT ENDIF etc. -------------------------------------------------------------------------- Q: Are upgrades to CIMplicity available? A: No. We may release updates in the future, but they will be released via our own channels, and made available from the same source that you acquired your version. -------------------------------------------------------------------------- Q: Can I purchase the advanced cycles, NC/BASIC, or other options for my CIMplicity? A: No. CIMplicity is a non-extensible system. You need one of the higher- level products in order to purchase upgrades. -------------------------------------------------------------------------- Q: I need to drive a wire-EDM, laser, or flame-cutter; but CIMplicity has no selection for such a machine. Am I out-of-luck? A: You are in luck. Follow the instructions for MILL machining. You will need to ignore or remove any Z values. -------------------------------------------------------------------------- Q: Once I have made a tape, how can I send it to my NC/CNC machine or punch? A: Many people use a modem program to do this. However, you may do it directly from DOS via the COPY command. For instance, if you have COM2 connected to a machine at 2400 baud, you could send a tape named M-TEST1 by typing: MODE COM2:2400,7,E,1,P COPY M-TEST1.TAP COM2 (You may automate this by customizing the file named "DNC.BAT".) -------------------------------------------------------------------------- Q: I'm having trouble getting my printer or plotter to work with CIMplicity. A: There are printer and plotter sections in the file named CONFIG.DAT. In addition, the plotter is controlled by a file named DRIV7470.PLT, which can be customized. Just be careful not to change unrelated values, or you may disable CIMplicity completely. -------------------------------------------------------------------------- Q: I was working with the system, when all of a sudden, geometry vanished or became unpickable! What happened? A: You selected a mask in the INFO TABLE. The purpose of the LAYER MASK is to make selected geometry temporarily vanish. The purpose of the TYPE MASK is to make selected geometry temporarily unpickable. -------------------------------------------------------------------------- Q: My CIMplicity crashes, locking up, or leaving menus on the screen. Why? A: Normally, if CIMplicity runs out of memopry or disk space, it will just report the problem and abort the current operation. However, if there is not enough room on disk or in memory for CIMplicity's scratch files, then it may loack up or abort. If this happens, your work is NOT lost, but can be found in the part file named BREAK.PRT. -------------------------------------------------------------------------- Q: Sometimes I perform a machining operation, but no toolpath gets built. Why don't I get an error message? A: CIMplicity always does tool-interference-checking, eliminating any moves that would gouge the part. This is not considered an error, but a normal part of the calculations. You have described a part that cannot be machined with the given tool. Check the tool width, side, and type; as well as the finish stock. --------------------------------------------------------------------------
