Step 7 - Avoid Strange Tool Movements at Sharp Inner Edges

1. Zoom-in to the area close to the connection between the two drive faces.
   
   At sharp inner edges, you are facing the so called dove tail problem (see image). This causes damage to the drive surfaces. It is caused by the Tilt the Tool Away collision check strategy.

   The dove tail problem is a very common issue with 5X machining based on surfaces. This will appear with all inner surfaces that have a fillet radius smaller than the tool radius.

   

2. Duplicate the procedure and edit it.
   Open the dialog and mark the Round Corners checkbox.
   

3. Select OK and Save & Calculate the procedure. Examine the results.
   

The result is smoother. The loop is no longer gouging the part.
