I am trying to set up a SPC scheme on several production lines that extrude electrical conductors and the like. We use a laser measurement system that measures the outer diameter in the x and y direction and then takes that average of these two values for the purpose of process control. How do I conduct a measurement system capability study on this device? The ideal way, I think, would be to run a calibrated cable of sorts through our process, collect data, and then analyze that data. Unfortunately, we do not possess such a cable nor do I know where to find one. Is there any other way I can do this? I do not feel comfortable implementing SPC on these processes without knowing to what degree I can trust my measurement system.
Thanks for the help.
