Use Results for mating components.

francoattolini
Hello,
At work they gave me the task of finding the way of proove that the measured part will mate another part even before trying this.
We have a whole team working with PC DMIS and the give us the results as reports, but to present to the customer we need to show graphically that the part will mate the mating part.
I use Solidworks and I was thinking on the possibility of importing the results, but maybe there is even the possibility of doing this directly in PC DMIS(?)
So the tasks are:
-to overlay the results form the CMM on top of the STP file or Solidworks model.
-Add the mating part and proove that there are no interferences.

Do you have any ideas?
Thank you very much

  • Unless you have a point cloud (full part scan) you won't be able to say yes or no about any interferance.

    Also, I assume that each of these parts has tolerance. Tolerance is there for a reason, meaning that if the part is within those tolerances, then they SHOULD build correctly, each part has tolerance. Comparing a point cloud of PART-A to the cad of PART-B will probably NEVER show that there is no interference since part A will be + here and - there. In a typical assembly design, where parts are to mate, there is no 'design gap'. So a part with even +/-0.005" tolerance on a mating surface will pretty much show that points from PART-A will interfer with the design of PART-B.

    Sure, you can over-lay the data, even in Pcdmis, but in Pcdmis, it will not do you any good since the 'data' for PART-B is CAD data and the data for PART-A will also be CAD data, Pcdmis is not a cad software, you can't do distance between cad entities. You would have to do this in a cad package. But, I can already tell you, even if it isn't point cloud data, you WILL have 'interference' between the data for PART-A and PART-B
