Process Quality Metrics for Mechanical and Electrical Production Lin
In order to applying defects per million opportunities (DPMO) to mechanical and electrical industries, this paper gives a clear and effective way to define defect opportunity, which is a key point in deploying DPMO.This paper is based on a project of establishing a quality index system for Siemens Electrical Drives Ltd. Based on the on-site investigation and PC-7912 calculation of DPMO and manufacturing indices for printed circuit board assemblies which gives a clear definition on DPMO defect opportunities for printing board assembly line, this paper proposes the rules to recognize, categorize and define the defect opportunities in motor production line by the joint efforts of the project members and the engineers.Component opportunity, assembly opportunity and operation opportunity are brought up to summarize the defect opportunities in the mechanical and electrical line.A set of defining rules is given to define according to the feathers of different lines.It has proven by Siemens facility that the defining rules are effective in measuring process quality for different sizes of motors.It can serve as a reference for other mechanical and electrical enterprises to define defect opportunities.
