  • Manual temperature compensation in PC-DMIS CAD++

    Dear PC-DMIS users,
    our supplier uses a DEA GLOBAL 07-10-05 to check aluminium parts with PC-DMIS CAD++. They tell us that the machine does not have the possibility to automatically compensate for part or axes temperature, nonetheless they are operating the CMM in a lab with temperatures between 23 and 24 degrees, apparently they cannot do better during the summer. The part is laid down on the surface plate without fixturing. I asked the operator to manually check the temperature of the part, define a variable to scale the measurements down (alpha*delta_T), run the program using this variable to scale all the measurements down to the reference temperature of 20 degrees and generate the report using the scaled down measurements, but he does not know how to do it. Would it be possible at all?
    Thanks in advance!

    If they have CAD++ they have access to the Temperature Compensation command in PC-DMIS. This can be set to manual mode, asking for the temperature when the program is run, automatically compensating everything.

    In 2019 R2 it's Insert -> Parameter Change -> Temperature Compensation…

      Thank you Andersl, I'll point this out to them. I appreciate that you took the time to answer!
