Profile of a surface
Limits how far a whole surface may deviate from its design shape.
In the shop
The programmed path sets the profile and the tool leaves scallops. Keep the nose or ball radius smaller than the tightest concave radius, and finish with a small step-over.
General shop guidance in our own words. The drawing and the standard it cites decide; verify on a sample part.
