How to Calibrate Probe using 2 Spheres

I am using a "T" calibration tool with one sphere towards the front and one towards the back. I need to calibrate A90B0 & A90B180. How do I go about doing this? Thanks for your help and I will attach a picture as soon as I can. Using PC-DMIS 2014.

  • If using multiple probes on your CMM (either in a rack or manually changed) decide on one probe (short stylus with a big tip if available) to be your MASTER probe.

    This is the only probe you ever use to take a manual hit on the ref sphere(s) after answering Yes, the sphere has moved. i.e. the sphere's must both be defined by T1A0B0 of the same probe.


    After that you can qualify any tip you want on any sphere (as long as physically possible) answering 'No, sphere has not moved.'


    If you only have one probe / module - then by default this is your MASTER probe - use T1A0B0 to define the sphere positions with this tip, then qualify the A90Bxx tips on whichever sphere is most suited.
