The Stock and the Fixture were created in a CAD system and exported as model files, such as STL, VERICUT Polygon, etc. In VERICUT, you will reference these model files to provide the size and shape of Stock and Fixture components. The Tool path origin is located relative to the stock model. The step at the end of the session shows how to save the session configuration so VERICUT can be quickly and easily configured to reprocess the tool path file. Session Steps: 1. Start from a 3axis machine setup Millimeter User file File Open Shortcut=CGTECH_LIBRARY File Name=fanuc3xm.usr, Open If prompted, respond as follows: Reset cut model? Reset / Save changes? No 2. Display Model axes and Driven Point Zero axes（加工坐标系） and set to one view only View Axes Select Model and Driven Point Zero Close View Layout Standard 1 View This sample session will simulate the sample idlerarm.mcd tool path file. The tool path requires a 400 x 615 x 100 piece of raw material (previously modeled in a CAD system). 3. Reference the sample idlerarm.stk model file for use as the Stock model Model Model Definition: Model tab Type=Model File Browse Shortcut=CGTECH_SAMPLES Filter =*.stk （认可文件） File Name=idlerarm.stk, Open Apply Fit The Xm, Ym, Zm axes represent the stock model coordinate system. The XDrivenPoint, YDrivenPoint, ZDrivenPoint axes represents the tool path zero point. 4. Reference the sample idlerarm.fxt model file for use as the Fixture model Active Component=Fixture Component Attributes tab Visibility = Workpiece View Apply Model tab Type=Model File Browse Shortcut=CGTECH_SAMPLES File Name=idlerarm.fxt, Open Color=Cornflower Blue Add OK Fit 5. Specify to simulate the sample idlerarm.mcd tool path file Setup Toolpath Highlight the fanuc3xm.mcd in the list Replace Shortcut=CGTECH_SAMPLES File Name=idlerarm.mcd, OK , OK The idlerarm.mcd file is an G-Code tool path that does not contain any information which describe the cutters used to machine the part. Therefore, a tool library containing the cutter description must be loaded. 6. Load a pre-defined tool library Setup Tool Manager File Open Shortcut=CGTECH_SAMPLES File Name=idlerarm.tls, Open File Close, Yes 7. Orient the tool path to the stock for proper cutting: The toolpath origin is in the lower left corner of the stock This action will be done by defining a table for the work offset: Setup G-Code Settings: Tables tab Highlight the existing table record under Program Zero Add/Modify Select Select From/To Locations From, Name = Tool To, Name = Stock Select the next to the Stock Move the cursor to the bottom of the stock forward left corner - when the arrow appears at the corner of the part (see below), left-click to select this location. The value in the field should be (-165 -200 0). Modify Close OK 8. Set VERICUTs Fast Feed value to indicate that cutting with a feed rate of 1550 MMPM or higher is unsafe for removing material Setup Motion Fast Feed=1550 OK NOTE: The programmed feedrate is 1500 MMPM. Material removed using a feed rate equal or greater than the Fast Feed value (or in Rapid mode) is highlighted in the red Error color and generates an error in the VERICUT Log file. This color is also used to indicate when crashes have occurred with clamps or fixtures. 9. Cut the stock model Press Play to End A User file is an ASCII text file containing the VERICUT session configuration. Saving a User file enables you to quickly reconfigure the system for additional tool path processing, as well as displaying models and model images. 9. Save a new User File named mill.usr File Save as Shortcut=Working Directory File Name=mill.usr, Save This session demonstrated how to setup VERICUT for processing a tool path file. Experience was provided defining a stock and fixture models via referencing CAD model files, supplying a tool path file name, orienting a tool path, and specifying how tool descriptions are to be obtained. The step prior to exiting showed how to save the VERICUT session configuration in a User file. The simulation session is repeated (and another cut model created) by executing VERICUT, opening the User file via File Open, then re-cutting the model. Session 6T- Simulate a Single Setup Turning Tool Path（ NC 文件） This session demonstrates how to setup VERICUT for processing a tool path file. The Tool path origin is located relative to the stock model. The step at the end of the session shows how to save the session configuration so VERICUT can be quickly and easily configured to reprocess the tool path file. Session Steps: 1.

Set VERICUTs Fast Feed value to indicate that cutting with a feed rate of 15 IPM or higher is unsafe Setup Motion Fast Feed=15 OK NOTE: The programmed feedrate is 10 IPM. Material removed using a feed rate equal or greater than the Fast Feed value (or in Rapid mode) is highlighted in the red Error color and generates an error in the VERICUT Log file. This color is also used to indicate when crashes have occurred with clamps or fixtures. 8.
