Upper Management is looking for answers/Justification on probe breakage

Hello ALL GURU's:
Here's a great post for a lot of input on WWGD (What would Gurus Do)?
Lets start by saying there are NOT an excessive amount of probes being broken yearly. I would estimate less that $500.00 - $700.00 yearly max, if that.
However, The uppers want justification.
Now, it has been suggested to slow the rapid in the machine settings, which would cause more cycle time on check parts that are in a Pallet setting.
There is a CRASH attachment from Renishaw. Anyone currently use these?. And do they work. Say on a .7x20mm probe or a 1mmx27mm probe?.
In our shop, we have 4 Cmm's that all have touch probes and 2 have vision as well. What would a normal (realistic) probe consumption be expected
at your place?. Mind you that the specific probes that we have in question are 1.5x30mm. 1mmx27.5 and .7x20mm. Sometimes it may just be human error (can't help that).
Maybe a slight misload, part has been machined or molded not into spec. Other times, maybe doing a manual align and you forget the rapid is on and "Snap". It happens.
I was asked to figure the FORCE in which a probe breaks. Well, honestly what other factors go into that one?. Are you rapiding, your prehit/retract too close and you touch the part and snap?.
Seeing as we are a high volume molding/machine shop with multiple parts at any given time to inspect via DCC. What is the best course of action to go ZERO probe breakage a year?.
This would not include Set ups, Prove Outs as well.
I am just looking for some insight on this issue from a lot of people who know way more than me!. Hence, picking the brains of the Guru's. ANY input would be greatly appreciated and if you want to keep it short and sweet. great. I don't want to consume too much of your time writing.
Thank You All Slight smile

  • The TP20 module seems to be pretty solid haha. I accidentally dropped it today and no issues after re-running some part layouts and comparing to previous results.
    As for the tips, it's easy to break one when you are programming and rushed or impatient, so take your time if you're programming online and even if offline, be sure to test slowly once online.

    Also no matter how dummy proof you have made your programs,
    I always run the CMM slow during a new batch of freshly produced parts. I do this for the first part only, this way if anything is damaged from production or extremely out of spec that may have been missed by qualities first off, you can be more confident. It's good to leave a prehit and retract of 5mm in case there is a form oopsie from production that slips through.

    Just my 2 cents Slight smile
