Profile tolerance

jim the
Hello,

I have drawing with a profile callout with a .004" spec. I am using PC-DMIS 2019 version.
My customer is measuring the part on Zeiss Machine.
The issue came up that they are able to spilt the tolerance to a +/-.002.
PC-Dmis, I am only able to enter the .004 using the "Exact Measure" option. I attempted the "Legacy" Mode this would not work either.

Is it possible to split the spec and have it read +/-.002, instead of the 0- 0.004?

Thanks,
Jim

attached is the drawing for reference

  • I have been looking into Zeiss for a while, we conform to ASME Y14.5M. I remember being told that Calypso uses ISO, but it can report similar results as ASME. As a matter of fact ASME 2018 is moving in that direction. ASME does not yet use the myriad of modifiers available to ISO. ASME Y14.5M 2009 reports profile differently than than ISO and ASME Y14.5M 2018. So yes you could conform to one and not the other in some cases. A really big deal with high precision parts that have curved / spherical geometry.

    No Datums, no orientation or location considered. Just form and you have a choice with the fitting. LSQ or Default. See help file one is more important / useful to the machinist
