Looking for opinions

The Hermit
I'm not currently at work, so I can't recall the exact model of my probe. I think I'm using the HSPX (?), with the large, magnetic base, maybe 1.75" diameter? I'm sure many, if not all of you have had this happen at least one time, if not many, many more. When you rotate, your probe catches the part, the fixture, or even the side column on the cmm and knocks the probe off. Here's my question. Do you automatically recalibrate, or do you kind of base it off the tolerance of whatever you're checking? I'm just curious how others approach this.

Thank you

  • I have an internal verification program that checks all of my tips in relation to the master tip for a quick gut check.

    We do the same thing. We basically just check that all the probes correlate to the Master Probe using the A0B0 probe angle on each. A quick check to make sure nothing got bent or shifted.

    I sometimes wonder if we should go a step further and check two angles for each probe (one at A0 and one at A90). So far, I have resisted the urge to get that paranoid. Checking just one angle will catch most problems.

    We do this check every morning and whenever something unfortunate happens, like when a probe is knocked out of the probe module. All the probe angles are calibrated once a month or when it is clearly needed.
