This paper applies the Six Sigma DMAIC methodology (Define, Measure, Analyze, Improve, Control) and solve the problem during the implementation. The purpose of this study was using the Six Sigma with Design of Experiment to find out the key factor to identify the optimal operating conditions of key factors for further verification of the best process capability.
