60mm disk qualification

[[La...]]

Hi all,

I have qualified/requalified several different diameter disks over the last 8 years with no problems until recently. When requalifying a 60mm disk recently, the disk has started rubbing the reference sphere as it completes the requal cycle. I have not had this problem with other diameter disks. What could be causing this problem?

Thank you in advance for you help!!!!!!

Hi Larry,

what do you mean with ,,the disk has started rubbing the reference sphere". maybe you have some pictures?

Do you have 2 reference spheres in your system? Check the reference sphere number used during the qualification routine.

I have two things to try. I have not had this issue. These are wild guesses.

pulldown menu
extras-settings-cmm-probe-Maximum diameter
Mine is set to zero. Maybe try 60mm?


extras-settings-cmm-probe-movement
Maybe try it without short movement?

Good luck!

1- Christian, what I mean by "the disk has started rubbing the reference sphere" is, when the calibration probes have automatically happened, and the disk retracts towards the start position, it doesn't clear the reference sphere during retraction.
2- Tom, there is only 1 reference sphere in the system.
3- Erik, I tried both of your suggestions, and they didn't help.

I'm open to other suggestions.
As always, I thank you in advance for any help.

I think I am attaching a video of the disk retraction issue here.

Larry, after taking the last qualification point, move away from reference sphere and add CMM position point with the right joystick button.

Thank you very much Dane!!!!!!!!!!
I never knew a position point could be put into a Calibration. I thought Calypso should have known how much clearance would be needed for the Disk, since it calculated the Disk's Diameter.
