[Me...] Posted February 25, 2019 Share Posted February 25, 2019 Hello, I try to find the fast way to control Z location (GPS cotation) of a watch spring. [img]https://www.jetons-royaux-marineche.com ... me__2_.jpg[/img] The spring has a reference surface and two holes to fix it on watch. The measure is done at the end of blade and tolerance is 50microns. I have a 100% sorting to do (lot size is about 60parts) and can't make a tooling to make an autorun. The best thing will be to have a form recognition to automaticaly detect my two references (the holes) and run the measure cycle automatically (and idealy repeat the measurement with regular spacing not accurate). Thanks for your future help!!!! Best Regards Cédric Link to comment Share on other sites More sharing options...
[Cl...] Posted February 25, 2019 Share Posted February 25, 2019 Are you using the CFS to measure the feature? What are you evaluating? Size, or form, or position? Are the parts fixtured? Link to comment Share on other sites More sharing options...
[Me...] Posted February 25, 2019 Author Share Posted February 25, 2019 I use the CFS only to measure the position of a plan in Z axis with a reference plan in Z axis. (no probing force) The parts aren't fixtured. Link to comment Share on other sites More sharing options...
[Cl...] Posted February 25, 2019 Share Posted February 25, 2019 So you are measuring the Z location of some feature on this part? What are you using for the base alignment? Link to comment Share on other sites More sharing options...
[Me...] Posted February 26, 2019 Author Share Posted February 26, 2019 The part drawing is here: [img]https://image.noelshack.com/fichiers/20 ... oc-z-1.png [/img] I make my origin with the hole 213 and make my alignment by construction with a straight between holes 213-214 (measured with camera). I make my vertical origin by construction of the A plan (probing with CFS). After that, I go to the Z zone and make a plan by CFS probing. Finaly, I call a localisation ISO tolerance between A and Z. (I have a 50µ tolerance) Measuring condition are: Part positioned freely on a glass plate Face-up orientation on the glass Part without any contraint On my OGP ZIP250 machine, I have an autocorrelation system and it permit a fast hole detection (without a precise positioning). After the autcorrelation, I can change the zoom automaticaly and have precise measure of 213 and 214. But I don't have CFS system on my OGP... Is there the same fonction on O-Inspect?

[Cl...] Posted February 26, 2019 Share Posted February 26, 2019 I'm not familiar with a "fast hole detection". I have a 543 O-inspect. The print is very blurry, but if I understand you correctly, you are measuring the counter bore depth inside the large ID? Link to comment Share on other sites More sharing options...
