[Lu...] Posted June 11 Share Posted June 11 Hello, I am having some issues with my smallest size rubies occasionally breaking. I am starting to believe that the measuring force might be to blame, since just a moment ago i was doing a manual pickup on an internal circle, and watched it move slowly to the wall and snapped off right when it touched the side. It seems to happen on occasion for many of the operators where I work at and I cant really think of another cause that would explain everything I have been seeing. The diameter of the stem is 0.4 mm, with the ruby size being 0.5 mm, currently it is set to 200 [mN] (which I'm not sure what that exactly means) which I noticed is the same measuring force as all of my larger probes, which leads me to believe that it has never been changed (the one who set a lot of this up no longer works where I work) Any advice is very appreciated, and please let me know any extra info that would be helpful for me to add (I would link the exact probe, but I think that's illegal here lol) 1 Link to comment Share on other sites More sharing options...
[Ch...] Posted June 11 Share Posted June 11 recommend 100mN if shaft is more rigid and passes qual, otherwise 50mN 1 1 Link to comment Share on other sites More sharing options...
[Lu...] Posted June 11 Author Share Posted June 11 (edited) Please sign in to view this quote. thank you very much! where did you find this information so i can use it in the future? And I am having difficulty finding the location to change measurement force, i found it in the "characteristic settings editor" under resources. Is that the only location? i tried editing it in the stylus system editor, but it wouldnt let me click on it, i also dont see a way to change it in a calibration program i have since i read that the measurement force must be changed prior to calibration but i cant find it there either. I am not finding anything off of google on how to change that setting, thanks again! Actually nevermind i believe ive figured it out. I was trying to change my automatic callibration program thinking the setting was in there while i actually needed to do the callibration manually via the "probing system qualification" menu where it prompts me to imput a probing force for the qualification. I believe all of the automatic qualifications will be set to the correct force afterward. Thanks though! Edited June 11 Link to comment Share on other sites More sharing options...

[Dr...] Posted June 11 Share Posted June 11 (edited) Please sign in to view this quote. "mN" in this context is millinewtons, a measure for the peak force the stylus sees. In practical terms, 200 mN is the weight exerted by ~20 grams (about the weight of a free-hanging AA battery), likely enough to snap a really small tip in the wrong circumstances. Definitely look into what Probing Dynamic does too; it's basically the approach speed, and going slower allows the force to ramp up gradually. The article Please sign in to view this username. posted provides some elaboration, and the Calypso manual & other forum posts tackle the "how-to" side.

[Lu...] Posted June 11 Author Share Posted June 11 Please sign in to view this quote. Thank you very much for the response! Looks like the probing dynamic was set to 100% which im thinking is the actual main cause (though i believe both were set too high) so now i have the probes set at 100 measuring force and 50% probing dynamic. Thank you all for your help! Link to comment Share on other sites More sharing options...
[Ow...] Posted June 12 Share Posted June 12 FYI, 0.5mm and smaller probes are the only probes I keep more than one back-up on. Link to comment Share on other sites More sharing options...
[Ri...] Posted June 12 Share Posted June 12 Man those 0.5mm are tanks - having said that I probably wouldn't use the default setting of 200; I'd recommend a maximum of 100, with the probing dynamics set to 30%. 0.3mm and 0.2mm are the ones that I worry most about. Below 0.5mm I typically prefer to use an XXT. 2 Link to comment Share on other sites More sharing options...
[Tr...] Posted June 12 Share Posted June 12 For input from here. We use .3mm and .6mm probes both are set at 50mN for Measurement Force. You can change this when you manually qualify each individual stylus and Calypso will remember this for future automatic calibrations. Our 1mm, 2mm, and 3mm probes are all set to 100mN. 1 Link to comment Share on other sites More sharing options...
[Ri...] Posted June 12 Share Posted June 12 I use 100 force and 100 dynamic. We run Ø0.5 ruby's without issues of breakage or meeting dimensional requirements. Two Micuras, fully parametric programs (maybe 80+ parts) might lose a stylus once a year and typically because someone did something they shouldn't have. All styli Ø1mm or larger are 200 x 100 (defaults). Link to comment Share on other sites More sharing options...

(Technically, the force 1 apple exerts on your hand due to gravity). So, .2N is about 1/5 the weight of an apple. You can extend this to torque. 1 Newton Meter is like holding a meter stick at one end and hanging an apple off the other end. 4 1 Link to comment Share on other sites More sharing options...
