Profile Surface & Profile Line
Profile Surface & Profile Line
(OP)
Hello everybody, who know wich is the diference between Profile Surface or Profile Line, i know Profile Surface, but, iam not sure of Profile line, and i dont know exactly when we must use this tolerance, and how we must apply it.





RE: Profile Surface & Profile Line
So to put that in real world terms - if you were to put a part on a CMM, surface profile would indicate a complete inspection of the surface, or a complete inspection within a specified boundary. For profile of a line, you would measure along the surface in a planar attitude - could be an offset, tabulated coordinate, etc. Surface and line profile are very similar to the idea of runout, and total runout, but applied to non-cylindrical parts.
Example of surface profile: aero surfaces, (generally +/- .030")
Examples of line profile: critical (mating) interface (generally +/- .005")
