We got a 321GLtp a few months ago, but I'm just now getting a chance to play with its tactile capabilities. I think I have the tool calibrations right, but I'm not sure what to expect.
I did a part alignment with a touch probe then measured the same circle and Z point with both the vision and the touch probe.
The diameter measured exactly the same with both methods. For its center point, the X is the same, the Y is .0002 off and the Z is .0125 off.
Is that an expected error on the XY axis?
Can the Z ever be calibrated to be the same or are there too many variables with lighting to make that possible?
Vision to Tactile (probe) Calibration chain should be as followed:
Vision - Calibrate to Ring, set to YES tool has moved.
Probe 1 - Calibrate to Ring, set to NO tool has moved.
Probe 1 - Calibrate to Sphere, set to YES tool has moved.
Probe 2 - Calibrate to Sphere, set to NO tool has moved.
Probe 3 - Calibrate to Sphere, set to NO tool has moved.
etc.
