Abstract

This study focuses on implementing the DMAIC methodology of Six Sigma to reduce the quality defects of the products occurring in the manufacturing process within a CNC (Computer Numeric Control) turning component machining company. The study follows the application of the DMAIC technique to investigate the defects, root causes and provide a solution to reduce these defects by evaluating the best process environment which could simultaneously satisfy requirements of both quality and as well as productivity. In this paper, six sigma with fuzzy analytic hierarchy process, for the manufacturing of a CNC turning component called front end cover is selected out of three projects and DMAIC model is adopted to investigate the defects obtained in the manufacturing process and also provides a solution to reduce these defects by improving the performance of the process. Normality test followed by process capability index and control chart has been computed for each major component of the process. Factorial experiments are also carried out to show the efficiency of the machine.
