Profile max div or measured point

browningdmis
We have a debate going on at work right now does PC Dmis calculate profile as Max deviation times 2 or worst measured point times 2? Is max deviation different then worst case measured point? How is max deviation calculated?

My thoight is its max deviation times 2. But engineering says that in violation of asme.

  • Switch CADGRAPH=ON and turn your multiplier up until you can see the arrows on the model. The blue lines represent your tolerance limit and the arrows show your deviation and are at the same scale as the tolerance lines., and you will be able to get a much better idea of what is going on here.

    Since all 6 DOF are constrained, it is not going to be best-fitting the profile, only calculating the deviations of the hits in the feature set relative to the datums.
