To Machine Open Pockets

The best way to machine an open 2D pocket in Inventor HSM is to use the 2D Adaptive Clearing strategy.

Initially, 2D Adaptive Clearing works similarly to 2D Pocket, and selecting one or more closed contours allows you to machine these as an ordinary pocket. However, if you also select a stock contour enclosing the selected contour(s), then 2D Adaptive Clearing machines everything from the stock contour to the selected contour(s), starting from the outside in.

To machine an open 2D pocket using the 2D adaptive strategy, follow these steps:

1. On the ribbon, click CAM tab 2D Milling panel 2D Adaptive to create a new 2D Adaptive Clearing operation.
2. On the Geometry tab, select the stock contour.

3. Next, select the contour with the open pocket.

4. Adjust the linking heights so that they match the geometry. Make sure that the top of the stock is above the depth of cut.
5. Click OK to generate the toolpath

The toolpath should now look similar to that shown below:
