Reduce the Failure Rate of the Screwing Process with Six Sigma Approach
نویسنده
چکیده
The Six Sigma approach is a well-structured method for improving quality level by detecting and reducing the variability of the process. Six Sigma approach also helps to achieve the company’s strategic goals by managing the several Six-Sigma projects. There are five sequential phases that are Define, Measurement, Analysis, Improvement and Control of the Six Sigma Project. These phases lead the way to carry out to the project. At the end, defective units will be decreased and/or the process capability index is increased. In this study, the screwing process is examined as a Six Sigma project. The aim of this project is to reduce the failure rate of screwing process in the white appliance factor in Turkey. Mentioned five phases are applied. The experimental design and analysis are handled. Finally, the pin shape and the type of handgun are determined as effective factors. Also, the best levels of these factors are found. The failure rate of screwing process is decreased from 30% to 14%. This study proposes the SixSigma projects with all phases sequencing and presents the results are originated the deviations from the manufacturing process.
