Guys,
I have a question. How many hits are needed to measure a hole?
At my company some people are starting a gage R & R test. I said that a minimum amount of hits are 3. With 3 hits it is not possoble to measure the roundness, so more hits are needed.
I then mentioned that I had heard somewhere that Prime numbers (ie 3,5,7,11,13,17 etc) are the best to use.
Is this so? If yes why?
Cheers
John
