Bumping

Vertical areas will now be machined using bumping machining technology. This is used mainly for semi-finish/finish operations to quickly remove material using vertical motions.

1. Edit the procedure and change the technology to Finish Mill by Limit AngleFinish Mill by Limit Angle.

   

2. Select the Flat 30 cutter.

3. Pick the boundaries shown in the following images:
   Select the contour, Exit, set the parameters, and click Apply to select the second contour.
   
   

4. Click on the Part Surfaces parameter and select Reset All.

5. Click on the Check Surfaces parameter and pick the three faces highlighted in the following image:
   

6. Click on the Part Surfaces parameter and select All Displayed part surfaces.
   

7. Set the parameters shown in the following image:
   

8. Unmark the Entry/Exit - Beyond Boundary Limits option.
   

9. Save and calculate the procedure.
   

When a part has near vertical walls and a large diameter cutter is used, bumping technology saves machining time when compared to layers technology.
