The commands offered on the Inventor HSM Express ribbon are shown below: Once a part or assembly file is loaded and a strategy selected from the CAM ribbon, the CAM Browser becomes active replacing the familiar Inventor Model Browser. The CAM Browser lets you view and modify all machining-related data in the current part or assembly. Hands-on: Inventor HSM Express

3 Create the Setup On the CAM ribbon, click Job panel Setup. The Setup operation dialog is displayed with the Model tab active. In Model group, click the Model button and select the part within the stock bounding box. In the Work Coordinate System (WCS) group, make sure that Stock box point is selected from the Origin: drop-down menu. Hands-on: Inventor HSM Express

4 From the Bounding box point: drop-down menu, select Top corner 3. Activate the Stock tab Select Add stock to sides and top- bottom from the Stock offset mode drop-down menu. Change Side offset to: 0 Change Top offset to: 1 mm Change Bottom offset to: 5 mm the OK button, or right-click in the graphics window and select OK from the marking menu, to exit Setup and close the Operation dialog. Hands-on: Inventor HSM Express

5 Face the Stock Perform a facing operation to clear the top face of the stock and ensure that it is completely flat. On the CAM ribbon, click 2D Milling panel Face. to open the Tool Library. Hands-on: Inventor HSM Express

6 From the Tutorial library, select Ø50 mm face. to close the Tool Library dialog. Hands-on: Inventor HSM Express

7 In the Feed & Speed group, change Lead-in feedrate to: 1000 mm/min Change Ramp feedrate to: 300 mm/min Change Plunge feedrate to: 300 mm/min Start the Calculation at the bottom of the Operation dialog box, or right-click in the graphics window and select OK from the marking menu, to automatically start calculating the toolpath. The toolpath is now calculated and a preview appears in the graphics window. Hands-on: Inventor HSM Express

8 Rough Out the Three Pockets The next step is to rough out the three pockets with an adaptive clearing strategy. On the CAM ribbon, click 2D Milling panel 2D Adaptive to open the Tool Library. From the Tutorial library, select Ø5 mm flat. to close the Tool Library dialog. In the Feed & Speed group, change the following values: Tip: Use Copy and Paste to duplicate the settings between the various parameter fields. Spindle speed to: rpm Ramp spindle speed to: rpm Cutting feedrate to: 1500 mm/min Lead-in feedrate to 750 mm/min Hands-on: Inventor HSM Express

Hands-on: Inventor HSM Express

16 Intermediate tool path simulation Right-click on the Setup folder in the CAM Browser and select Simulate (All) from the popup context menu. The Simulation player is displayed in the graphics window. Be sure to check the Stock tab. first rewind and then Play button on the Simulation player to playback the defined toolpaths. When the simulation is complete, click the Close button in the Simulation dialog box, or right-click in the graphics window and select Close from the marking menu. Hands-on: Inventor HSM Express

17 Rough Cut the Outside of the Part Use an adaptive clearing strategy to rough cut the outside of the part. On the CAM ribbon, click 2D Milling panel 2D Adaptive to open the Tool Library. Make sure that tool Ø5 mm flat is still current. Activate the Geometry tab the Geometry tab and ensure that the Pocket selections button is still active. Disable the Machine cavities check box to ensure that machining occurs on the outside of the selected profile, and not the inside. Attention: When you disable Machine cavities, the Stock Contours check box is automatically enabled and the stock contour is displayed on the part. Select the outer profile as shown in the following image: Hands-on: Inventor HSM Express

18 the Heights tab. From the Bottom Height drop-down menu, select From model bottom. Set Bottom offset to: mm Start the Calculation, or right-click in the graphics window and select OK from the marking menu, to exit 2D Adaptive and create the toolpath. Hands-on: Inventor HSM Express

19 Finish the Outside of the Part Finish the outside of the part with a 2D Contour operation. On the CAM ribbon, click 2D Milling panel 2D Contour. to open the Tool Library. Make sure that tool Ø5 mm flat is still current. the Geometry tab and ensure that the Contour selections button is active. Select the same outer profile as you did in the previous 2D adaptive operation.

32 On the CAM ribbon, click Toolpath panel Setup Sheet An html tool setup sheet will be generated. Hands-on: Inventor HSM Express

33 Next, click On the CAM ribbon, click Toolpath panel Post Process. The Post Process dialog box is displayed. Tip: As an alternative, you can also right-click on the Setup folder in the CAM Browser and select Post Process (All) from the pop-up context menu. Select heidenhain.cps - Generic Heidenhain from the Post Configuration drop-down menu. Accept the default output folder or choose another. Start the post processor by clicking the Post button. Accept the default file name or provide another. the Save button. Because the Open NC file in editor check box is enabled by default in the Post Process dialog box, the post processed file is automatically loaded into Inventor HSM Edit. Hands-on: Inventor HSM Express

34 From the editor you can edit, inspect, and transfer your NC program to your CNC machine. The editor provides a number of CNC code-specific functions including line numbering/renumbering, XYZ range finder, and file comparison. The editor also features a DNC link for reliable RS-232 communications with a variety of CNC controls. Remember: You can also post process individual operations by right-clicking the operation in the CAM Browser, and selecting Post Process from the pop-up context menu. Congratulations!
