Re: Gage R&R on a Length Gage Made In-House
It sounds like the setup bars are essentially masters for the air cylinder device. I would calibrate those internally or externally per your QMS requirements.
Those in turn are used to set the device. You'll probably need to write a procedure for the use of these in the setup of the machine. Probably set some intervals for the device to be set with those length bars and establish a tolerance that the device should be reading when it measures the bars.
