Profile Tolerance

Michael Tran
Hello All,

I have a part that the drawing only given a couple of FCF for True Position for 4 holes, Angle related to Datum A B &C and a profile tolerance of .030. I have to use a CAD model for inspection.

I was able inspecting the holes. For the remaining periphery of the parts, have been told because Profile Tolerance was given, I have to use a feature in PC-DMIS to inspect the periphery of the part, include angles. Please see the picture attached.

I am newbie to Romer Arm and PC-DMIS and working Profile Tolerance. Your guidance is greatly appreciated.

    Thanks for your quick respond. The Surface Profile Tolerance called out on General Note, "THE LOCATION OF ALL PART FEATURES ARE SUBJECT TO A SURFACE PROFILE TOLERANCE ZONE OF .0300 WITH RESPECT TO THE PRIMARY DATUM A, SECONDARY DATUM B, AND THE TERTIARY DATUM C". Also attached is another picture which showing Datum B and C. The drawing is none dimensional and only show FCF and I have to inspect to CAD model.

    Thanks
