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

  • We go thru several thousand dollars worth of styli each year. every now and then it will be when we prove out a program but the majority of our problems are operators loading the wrong operation program or entering the wrong op for a parametric program or not setting the part up correctly (not reading or following instructions). We currently have 1400+ programs in our working directory and another 6k plus in doc control and all have been used at one time or another but people can't seem to follow instructions with pictures.

    Management knows this is an issue and they do ask us to do what we can to help but when shop floor people run their own parts they will get broken and they understand that. We've got 13 CMMs and they are ran by approximately 200 different people each day.

    we had a barcode scanner setup and working when I left 7 years ago. Ops would scan the Job number then op and it would open and run the correct program. That was ditched within a year after I left. I have heard rumors that they are going to bring it back next year but nothing definite.
