What is profile tolerance on a rough surface?

Explanation:
Profile tolerance defines a tolerance zone around the true profile of a surface, governing its overall shape and orientation. For a rough surface, this means the actual surface must lie within the envelope defined by that profile tolerance. It controls the boundary of the surface, not depth, diameter, or position. So the key idea is that profile tolerance enforces that the surface’s boundary stays inside a specified envelope around the intended profile.
