The tool is specified as the default tool via the Override feature. Supplying a tool description in this manner is useful when the tool path file does not contain tool descriptions, or to test alternate tools. This session demonstrates defining a corner rounding mill tool assembly similar to that shown below. The Tool Manager allows tools having almost any shape to be easily defined, as well as provides collision detection between non-cutting portions of the tool and the workpiece. Session Steps: 1.

Set VERICUT to change tools based on tool number and cut the model Setup Toolpath Tool Change By=Tool Number OK Reset Model Play to End Session 11- Control a Tool Path Simulation（ cls文件） This session shows how to control the simulation of an APT tool path file. Full control is provided over the interactive simulation enabling users to interrupt the simulation at any time by pressing Stop or the Escape key. In addition, VERICUT can be configured to stop tool path processing based on a variety of conditions, including: when errors are detected, after tool changes, after a specified number of cuts have been performed, etc. This session demonstrates practical use of VERICUT simulation controls. Session Steps: 1. Open the rib.usr User file File menu Open Shortcut=CGTECH_SAMPLES File Name=rib.usr, Open If prompted, respond as follows: Reset cut model? Reset / Save changes? No 2. Open the Status window to monitor the machining operation Info Status 3. Configure VERICUT to use only the cutting portion of the tool during the simulation； cutter descriptions are to come from CUTTER records in the tool path file Setup Motion Clear Display Holders in Workpiece View 4. Configure VERICUT to stop after tool changes and when an error is detected Stop At=Tool Change Select Stop At Maximum Errors Stop At Maximum Errors=1 5. Configure VERICUT to issue an error if material is cut using a feedrate of 100 or higher Fast Feed=100 OK 6. Cut the model - why does VERICUT stop?

Use Feature/History to identify the tool path record responsible for cutting the upper clamp (see below) Analysis X-Caliper Feature/History Tab Click on machine cut in upper clamp - Record Number: 959 17. Review the motions that caused the collision with the clamp Analysis Toolpath Review Click on machine cut in upper clamp The block responsible is highlighted in the upper window； GOTO/12.7461,9.3317,-0.9500,0.0000000,0.0000000,1.0000000 right-mouse click with the cursor on the highlighted line Set Current right-mouse click with the cursor on fourth line above the highlighted line Set Start right-mouse click with the cursor on fourth line below the highlighted line Set End 18. Step (single block) through motions that cut the clamp In the Toolpath Review Window； Rewind (rewinds to the block assigned as start) Single Step Single Step (or pressing the Space Bar will repeat Single Step) Single Step You can also step backward with Step Backward Session 12- Standard vs. FastMill Simulation（ cls文件） This session demonstrates how to process VERICUT faster with different settings and with using FastMill- a verification method that cuts the VERICUT model very quickly without displaying tool motions. The FastMill cut mode is recommended for processing large amounts of tool path data intended for use on 3-axis mill machines where all cutting is on the Z+ side of the workpiece. Session Steps: 1. Open the sample idlerarm.usr User file File Open Shortcut = CGTECH_SAMPLES File Name=idlerarm.usr, Open If prompted, respond as follows: Reset cut model? Reset / Save changes? No 2. Configure VERICUT to stop after cutting the model with 100 cuts each time Play to End is pressed. Setup Motion Stop At=Num of Cuts Enter 100 in the field displayed to the right of the Num of Cuts option OK Configure VERICUT for maximum collision detection A major factor in the accuracy and performance of the VERICUT session is the Cutting Tolerance (ref. File menu Properties: Tolerance tab). This value is similar to specifying an INTOL/OUTTOL when generating a tool path. For maximum collision detection, the fixture holding the workpiece should be modeled in VERICUT, and descriptions of cutting tools should include the non-cutting portions of the tool: shanks and holders. Assuming shanks and holders are defined for the cutting tools in the simulation, using these provides collision detection of the non-cutting portion of the tool assembly against the stock or fixture. 3. Specify .05 mm Cutting Tolerance（影響顯示速度、影響顯示質(zhì)量不大） File Properties: Tolerance Tab Cutting Tolerance=.05 OK 4. Configure VERICUT to use tool holders defined for use in the simulation Setup Motion Ensure Display Holders in Workpiece View is selected OK 5. Fit the model in the view, then open the Status and Toolpath windows to monitor the simulation Fit Info Status (relocate window as desired) Info Toolpath (relocate window as desired) 6. Single step to create the model database, then cut the model with 100 cuts Single Step Wait for the BUSY light at the bottom of the VERICUT main window to go out before continuing. Press Play to End - note VERICUT processing time 7. How many errors were detected? Ref. Info Status: Errors field -9 errors Configure VERICUT for maximum collision detection - maximum speed For optimum performance, ensure axes are not displayed (View menu Axes), and close all VERICUT windows that are updated during the simulation (Info menu Status, Info menu Toolpath, etc.). Verification speed can be increased by turning the display of the tool off and reducing the size of the displayed models, since this reduces the amount of graphics activity that occurs in the VERICUT window. This is especially true when simulating 5-axis motions, displaying large cutters, or shanks and holders during the simulation. 8. Close the Status and Toolpath windows, then turn off the display of the tool Status window: Close Toolpath window: Close Setup Motion Tool Display=Off OK 9. Zoom out twice, then refine the display prior to cutting Press Zoom Out 2 times Refine Display 10. Cut the model with another 100 cuts Play to End - note VERICUT processing time Increase the Cutting Tolerance for faster processing Cutting Tolerance may be able to be increased while maintaining sufficient error detection results. Increasing the cutting tolerance increases the speed of the simulation, and requires less system resources and space to store the model database. However, the accuracy of cuts in the model is also reduced. The cutting tolerance also directly affects the results from AUTO-DIFF, OptiPath, holder collisions, Fast Feed errors, dynamic rotation speed, zoom speed, etc. In general, the value entered should reflect the accuracy needed for detecting cut-related errors and analyzing machined model features, such as required for model inspection by AUTO-DIFF, optimizing tool path motions with OptiPath, or exporting cut model data. 11. Reset the VERICUT model, then increase the Cutting Tolerance to .2 mm Reset Model , Yes File Properties: Tolerance tab Cutting Tolerance= .2 OK 12. Single Step once, then cut the model with 100 cuts Single Step Play to End - note VERICUT processing time Were the same quantity of errors detected as with the smaller Cutting Tolerance value? - Yes (ref. Info Status) Make sure to close the Status window when you are finished. Configure VERICUT to process fastest - reduced collision detection When checking for collisions with fixtures and the non-cutting portion of the tool assembly (shank/holder) are not required, remove these from the simulation to gain performance. In short- for optimum tool path verification speed simulate only what is required for the desired level of collision detection. 13. Reset the VERICUT model and blank (remove) the Fixture from the simulation Reset Model , Yes Model Model Definition: Component Attributes tab Select the Fixture model displayed in the VERICUT window Visibility=Blank OK 14. Use only the cutting portion of the tool in the simulation Setup Motion Clear Display Holders in Workpiece View OK 15. Single Step once, then cut the model with 100 cuts Single Step Play to End - note VERICUT processing time Note that since the fixture, shank and holder have been removed from the simulation, collision errors are no longer reported. However, the stock has been cut through where the cutter had previously plunged into the fixture (see below). At this level of verification, the cutter can be re-displayed with a minimal affect to performance. 16. Reset the VERICUT model, then turn on the display of the cutter and configure VERICUT to process the entire tool path file Reset Model , Yes Setup Motion Tool Display=Solid Stop At=End OK 17. Single Step once, then cut the entire model Single Step Play to End - note VERICUT processing time 18. Reset the VERICUT model, then configure VERICUT to process the tool path file without animation Reset Model , Yes Setup Motion No Animation OK 19. Single Step once, then cut the entire model Single Step Play to End - note VERICUT processing time Configure for FastMill verification Speed of verification is dramatically increased by using the FastMill cut mode. This verification method is designed for use with a fixed tool axis in a milling tool paths. 19. Reset the VERICUT model Reset Model , Yes File Properties: Tolerance tab Cutting Tolerance= .05 OK
