Re: Gage R&R Results - “Number of Distinct Categories = 1”
Good idea. Even a friction mic can create error by impact. If an operator spins down at a different speed each time, it can still create error. Standard micrometers are generally just bad news. I have seen huge GR&R improvements with snap micrometers.
Yes, as stated above, I used a friction mic which minimizes this error. I believe this error is a main cause when setting or zeroing the mic. We ordered a snap gage, so hopefully another gage r r will yield better results and will justify spending the money on snap gages.
