PAM

PAM is a roughing toolpath which anticipates the finishing operation, with purpose to ensure a constant engagement angle in finishing.

Key Points

Check that the tool engagement angle in finishing is always 38°, in straight line and in any convex and concave corner.
To do so, the roughing PAM calculates a variable allowance all along the toolpath.
