Question regarding calibration - this is kind of a long lead in, thank you for reading until the end. We are a small machine shop currently working towards our AS9100 certification. We are 10-12 employees, we have a consultant who is assisting, I was hired to help with this my experience is with ISO 9001 and I was asked to basically be the interpreter, to help the company understand while keeping our certification as simple as possible. The goal is to be able to provide services to new company's, some of which could include aerospace. The company has always been meticulous with tracking of material, processes, inspection and all of there processes so my job has been pretty basic to document what they do. Every part is released, every job has first article inspection that is documented, when job is complete every part is inspected through our inspection department, that inspection is documented with material certs and outside process certs, all this is documented and sent with each part. We have had our standards sent out and outside calibrated now we need to calibrate our inspection tools. My question is if we are calibrating all of our inspection tools, even our 2 CMM's are outside calibrated do we need to track/calibrate each individual operators tools? Can we mark them as reference since nothing leaves the company without going through our inspection department? Thank you in advance!
