Re: GRR on ID with set of pin gauges

Hi Miner,
Yes. You are correct that the resolution will be limited by the increment of those pin gauges. You generally can't go further than 0.005 increment and I doubt if the hand feeling of 0.005 is distinguishable or not. So I usually recommend engineer to explain to customer and seek for their endorsement. The chance customer will accept this is not low to my experience especially when the holes are functioned to have shaft to fit into, ie. the pin gauge measurement simulate better the real world situation as in their assembly process. If you use point touch measurement equipment you may not get the least thru hole diameter.
