Reduction of Rejection in Valve Manufacturing

Abstract

Rejection of valves in dimensional inspection is reduced. These measure of excellence is done to improve evenness of job parameters specified by the customer. This paper provides methodology to avoid rejection of valvein groove grinding machine, using various quality improvement tools like cause effect diagram and process monitoring techniques. This tool provides easy way to finding problem causing machine and rout cause of the problem. This reduction of rejection is attained by providing fixed back stopper with movable ejection pin in groove grinding machine. Implementing these technique minimize the rejection of in final inspection for delivery. Variable gauge is designed to measure datum to groove length.
