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.

  • John,

    I was able using the vector point and created group and used surface profile for dimensioning. Then the system crashed on me so I have to start over and not sure how did the first time. What I am stuck right now is grouping all of the Vector in set for surface profile dimensioing.

    Here the steps

    1) Alignment (CAD and Part to CAD Model)
    2) Defined Datum Plan A B &C
    3) Selected Point Only Mode
    4) Hit point on part surfaces
    5) Selected all hit points in Edit Windows
    6) Selected Surface Profile dimensioning
    7) Try to select all hit points and assign to datum plan, but PC-DMIS popup with "Error in best fit 3r alignment" and repeat 3 time and in only let pick single instead of group to set FCF. Please see attached image and let me know what I did wrong or missing

    Also when I hit control Q to do the alignment of the part, the popup box appears with "Machine Error". Please see attached and let me know if it is normal I did some wrong.

    Your help is greatly appreaciate
