Hello Folks,
We had an issue with a stamped part in which the hole diameter was oversize. We found out that the gauge we are using to verify the hole was giving us false readings. We found this out by taking a 3 point Mauser bore gauge and measuring the hole diameter vs the two point bore gauge that was giving us false reasons. In my opinion, we have found the root cause by using a different gauge and verifying the results of that gauge to a CMM.
The customer wants me to do up a 3 legged 5 why, but I'm not sure on how to tackle the on why is was not caught or the systemic issues associated with the defect. Has anyone had any experience with an oversized hole diameter in which the gauge was the direct result?. The team here is stumped on the next process and non of us have been through a 5 why.
Any help would be greatly appreciated!
Thanks,
