Gage R&R Results - “Number of Distinct Categories = 1”
Can someone help me explain my Gage R&R results? I know most of my problem is I have “Number of Distinct Categories = 1”. I guess I don’t understand why I keep getting that. I attached my data and a few graphs from Minitab.
Some background info. The part feature being measure is a 1.181” OD with a tolerance of 0.001, so my UCL=1.181” and my LCL is 1.179”. I measured with the 10/1 rule so I included the 4th decimal place (tenths or .0001). Is this my problem?
I also run two different software programs and get two different results? What does everyone else use?
Any help would be appreciated.
