Abstract

In this world of competition, maintaining product quality is an important criterion of companies. Six Sigma is a tool which is used to reduce the rejections and improve quality. This paper describes the implementation of Six Sigma on a production line. The production line manufactures camshafts, facing an elevated rejection rate. The DMAIC (Define Measure Analysis Improve Control) methodology assists to minimize the number of rejections. The rejected camshaft is either send to scrap or for rework. To unravel the source of defects, Six Sigma provides a statistical approach to comprehend the root cause of defects. By deducing possible reasons for defects, it is easy to perceive the source of all variations. By implementing Six Sigma the quality level of production line has been improved.
