SP25 calibration issue

JEFMAN
Please note that this thread is not in the OFF TOPICS section, so only clever answers are welcome !!!

I greet you all, colleagues.
I have a small problem that tends to come and go when calibrating angles. I work with many styli and use a 9-slot magazine for this. Each stylus has about 10 different angle positions. When I did the calibration, two angles on different probes were out of tolerance. One probe has a CM25-2 probe and the other CM25-3. And at the same time, PSDMIS accepts the calibration result without asking the operator. The next day I did a similar calibration and the result was OK.And always out-of-tolerance angles equal to A90 or more than A90 It is very strange . I have been working in this mode for 3 years and there were no such problems. And this year it started. I check the probes visually and do the cleaning before each calibration the same way always. What could be the problem ?

  • Hello Jeff. Excuse me for being away for such a long time (production issues forced me to work on a tough problem for two days).


    I calibrated in automatic mode and set the marker to the reset of probes. For the probe master, I told the machine that the sphere changed position and at startup I selected YES (take a point on the sphere manually). As a result, for the A0B0 angle, the probe master THEO and MEAS the measurements became the same. All probes were calibrated OK. But on the probe SP25M-2_L40_D1-D1, the set of angles did not pass the calibration. I observed visually ---- there was a feeling that the machine does not see zero(center of spher) for this probe. I checked the probe assembly --- everything matches. As a result, for each angle of the probe SP25M-2_L40_D1-D1, without changing the position of the sphere, I manually calibrated oll angals (each time pressing YES to take the point of the sphere manually) After that, all the results became ok. After that, I measured all the standards of our production parts ---- Everything is ok. That is, PC-DMIS has accepted all the positions of the probes. The problem is solved, but now I think where this problem came from. I have to find out why this started so that I can have an understanding of the problem in the future.
