[Ha...] Posted June 23, 2018 Share Posted June 23, 2018 Quick question about calibration programs. We have always located the sphere with the Master Probe then run each probe individually through the full qualification (12 positions using RDSCAA). However, I have no problem creating the calibration program and adding the "probing system qualification" and qualify passive. If you qualify passive, it only does the 6 positions not 12. Is this accurate enough or should we continue to use full qualification on each probe individually? Would appreciate any suggestions! Thank You!

[To...] Posted June 25, 2018 Share Posted June 25, 2018 Test the re-qualification of an RDS-CAA stylus system by reporting the Z value of a point on top of your part at A0/B0. Then, copy and paste this point and edit to A90/B0, and another at A180/B0 and another at A-90/B0 and so on. Compare the reported Z values. Then, do a Full Qualification and run your program again. Please post the variation. Link to comment Share on other sites More sharing options...
[Ha...] Posted June 25, 2018 Author Share Posted June 25, 2018 Thank You Tom, Here are the results from both re-qual and full calibration. Besides position A0 B0, all other positions seemed to be off about .0002.FULL.PNGRE-QUAL.PNG Link to comment Share on other sites More sharing options...
[To...] Posted June 25, 2018 Share Posted June 25, 2018 Your re-qual looks better than the full qualification. In years past, the re-qual was considerably worse. Maybe the issue was fixed. Granted this is only in 1 direction involving only the A rotation but I've seen as much as .002" deviation on my machine, as well as a couple of our customers. Once, I tried to incorporate many other probe angles but never got around to it. . . Link to comment Share on other sites More sharing options...
