Disc probe error

[[SH...]]

My disc probe gives 0.01mm error after a collusion ( by my colleague). Does any method to bring it back. Visually looking good , I calibrate it using reference sphere .I calibrate it two three times.

Disc probes should be qualified supplementary with a ring gage.

How do you go about that Richard? I've pretty much got the same method from a few different people but basically the method I use is to create a short program with an accurate probe like a 3mm Standard, get the size & location of the ring gage and then measure it with the disk probe and tweek those 3 things to match the 3mm Stylus to calibrate it.

You got it.

You create a measurement plan that measures a certified ring gage (the higher the class the better, XX or XXX) with a normal qualified stylus. Then measure the ring gage with your disc probe. You will comp the stylus data manually based on the differences in X, Y, and radius (assuming you are working in the XY plane).

Yes, I have that Tom Oakes documents,but problem is that I don't have a ring gauge of same size. My disc probe in YZ plane.

It should be possible to use the qualification sphere as well.

I correct it using a plug gauge. Thanks for the comments..
