Need help!! Not sure why PC-DMIS keeps giving me bad results. I have created different alignments, different hits, different workplanes and views but PC-DMIS still gives me wrong numbers. Any suggestions on what is going on?
On the blueprint I have provided the Dimensions I need and the results I am getting.
I am currently running on PC DMIS 2021.1
CMM SF 7.10.7
1) Make sure probes are calibrated correctly in respect to each other. As someone said look up 'MASTER PROBE' and get your head round the concept then make sure you're stacking to it.
2) Alignment should be Level > Rotate > Origin (in that order) but I don't think in your case it will matter (but as a test you can always dimension the datum features and check they measure zero in their respective axis)
3) If you change your program to establish the alignment ABC first, you can then offset by 1.012 and then round by 35° so you're 'looking' straight down the cylinder. (XYZ will be 0,0,0 and vector will be 0,0,1) before measuring the angled cylinder.
3) Make sure your constructed planes are don using best fit recomp (currently they're just best fit)
4) Report the form of your features (datums and cylinder) to make sure you're not shanking out or have a bad hit somewhere in the datums skewing the results.
5) Finally, you're saying the CMM results are wrong, but how are you verifying this or checking it otherwise? Are you sure the part isn't bad?
Ok thank you, I will these suggestion out hopefully I get good results. And we checked the center of the holes with an Indicator and the Keyence/gage pins for the other dims
