Has anyone done accuracy tests on an optical style touch probe versus a mechanical? I've been told there is a small difference which usually shows up in form, but looking for real world numbers. I currently use an HP-THD (now an HP-THe), which is a tp200 I believe. But after replacing 2 probe bodies in the last year and 2 months at over $3k a piece, I'm searching other more robust options. Like the older tp20. Is it worth the switch? am I losing that much accuracy? Occasionally I do get jobs with a +.0005/-0" tolerance which I think may be affected, but could be worked around with deltronics pins. Does anyone else here use tp200 or the newer and have problems? I know the first module may have gone bad due to the previous cmm programmer. I was told when I started my job here that he crashed it a lot. But this new one I've had on for the last year has never been crashed, dropped, even looked at wrong. TIA
That was gonna be my next question, is there a better option. I currently have 3 modules for my HP-THe. One with a mark in it probably from previous operator running it in to something. The other 2 have 2 years worth of probing, so i'm sure it won't be too long before having to replace the modules. Might as well buy all new.
