This document is a process FMEA for the rotor stacking process. It identifies potential failure modes including incorrect stack length, improper welding, and burrs on stampings. Current controls to prevent failures include work instructions, operator checks, calibration of measuring tools, and preventative maintenance. Recommended actions focus on updating work instructions, improving operator checks, and ensuring stampings are properly rotated during stacking. The overall goal is to reduce the risk priority number to below the threshold value.
