[Lo...] Posted October 1, 2020 Share Posted October 1, 2020 It finally happened. I broke a probe, actually I just chipped it. The crash sounded worse than what the damage is. Now my question is, should the CMM be checked out or is it tough enough to handle a rookie crashing probes?

[Ow...] Posted October 1, 2020 Share Posted October 1, 2020 What kind of CMM is it? What type of head, Vast active scanning, XXT passive scanning, Articulating?

[Cl...] Posted October 1, 2020 Share Posted October 1, 2020 If we have a crash, we use a Master Part to verify accuracy hasn't been affected. Run the master part, compare deviations from original, and if within reason, machine is most likely OK.

[Ow...] Posted October 1, 2020 Share Posted October 1, 2020 I've always been told the worst kind of crash to cause damage is straight down or if the head itself (not the probe) actually hits something traveling in Y or X. Had an accura (2006 model) that a guy from the company that sold it to us run the head into the probe racks and knocked the CMM out of square. That said, if you just knocked the probe and probe plate off the head (I'm perfect and never done it 🤣 ), ..you'll probably be ok. As Clarke mentioned, a calibration artifact or master part should probably be checked to ensure to. Even a part that, lets say you measured before the crash could be used, throw it on and see if it repeats the same.

[Ro...] Posted October 2, 2020 Share Posted October 2, 2020 Hey, congratulations and welcome to the club. I have directly or indirectly (piss poor programming strategies) broken probably 50 probes, some very light and some that ripped the head off the electro magnetic base of the Vast and broke all the probes on a cluster. I would say in general that you should be fine. Now like Clarke said if you had a -Z drive directly into the part that could be bad, but i would say any styli since you just crunched the ruby and didn't even break the carbide you're gonna be fine. When we take the rayco plate off for annual service its fun to dig thru all the dirt & dust to find all the bits of ruby & carbide that fell down into the screw holes 🙂 Link to comment https://qualityforum.zeiss.com/topic/14466-i-finally-broke-a-probe/#findComment-75882 Share on other sites More sharing options...
[Lo...] Posted October 2, 2020 Author Share Posted October 2, 2020 Cool thanks for the info everyone, I appreciate it. Unfortunately the crash was on the -Z axis. The probe is hardly chipped you actually have to look at it under a microscope to see it. But the crash sounded like a train wreck, or at least thats what I was thinking when it happened. I have taken it out of service obviously. I will check out a few master parts and go from there. And it's nice having friends in the machine shop! 🤣 🤣 🤣 🤣 Link to comment https://qualityforum.zeiss.com/topic/14466-i-finally-broke-a-probe/#findComment-75884 Share on other sites More sharing options...

[SH...] Posted October 2, 2020 Share Posted October 2, 2020 Please sign in to view this quote. 50 probes, my goodness.. I have broken four probes during my 2 years calypso experience. All I have done during my dry run of a new program ,I never broke a probe during ordinary running. I gave wrong clearance planes, that was my mistake.My machine is still in good condition.No collision with probe head, thanks god.
