Tip Calibration Process

Smasherofprobes
Hello all, could you please verify that I am calibrating my tips properly! I recently calibrated my machine and my results seem offset in one axis. (Calibration sphere comes off the table after every calibration)

I start by selecting A0B0 only ( Say Yes, Sphere has moved) Calibrate it by itself

Then I Select all tips (Including A0B0) and say No, Sphere has not moved)

The second time I calibrate my tip set should I be including A0B0? Also, Do you guys have a separate probe file called something like "Master probe" with just A0B0? or do you calibrate it within the tip set.

I haven't been on a machine in many years and I'm trying to remember the correct way to do this.

Thanks and my apologies if this is a re-post.

  • You always want to use a master probe for locating the sphere on the table regardless if the sphere moves or not. Always answer Yes man or Yes dcc. All other probes and tip need to be answered with No. Master probes are usually short with a large ball like a 5x10 or 4x10.

    I believe the purpose of the master is not only to locate the sphere but to also have the least defection as it probes. So a large tip with a short stylus is ideal for touch trigger. I like to use a 5x10 or 4x10 for touch trigger CMMs. I sometimes use a 5x20 for analog heads since that is the probe used for the lower matrix. Not every situation is the same so the best thing to do is to designate a probe as the master probe and only click yes for that probe/tip. All other probes and tip angles need to be answered no.
