Abstract: To reduce the failure rate in the process of using the deck machinery clutch of the windlass,the DMAIC model of 6Sigma is used to solve this problem.For the failure frequency and type,a qualitative analysis method is adopted to analyze the main causes,and then the DOE experimental design is introduced to improve the process of parameter configuration and optimization.In order to determine the fitting model,a quantitative analysis is conducted by sifting appropriate experiment factor and factor levels and then by a residual analysis the effectiveness of the model is determined so that the production gets in control revolving around the model and customer satisfaction is enhanced.

Key words: clutch, Six Sigma, DMAIC Model, DOE experimental design method
