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
I was told by the manager that they had all the scanning options installed incase they wanted to go that direction in the future. They said it wasn't an added cost to pre-install whatever it was they needed to install to have the scanning option.
