Quality Control And Improvement Of Manufacturing Process For Aviation Parts

Development of High-end equipment manufacturing industry during the12th Five year plan released by Ministry of Industry and Information Technology of the People’s Republic of China, which had proposed that trunk airliner able to completed its maiden flight; regional Jet can be successfully developed; achieve hundreds of regional jet be sell in the market; establish a sustainable development of aviation industry system in aviation equipment aspect. Shanghai Aircraft Manufacturing Co.,Ltd.(SAMC) is the final assembly and manufacturing center and one part of Commercial Aircraft Corporation Of China,Ltd. Under the chances and challenges coexist situation, an advanced, effective quality control system must establish to ensure the trunk airliner program accomplish successfully. This report would mainly focus on methodology of quality control during Parts fabrication process in C Company.This context firstly reviews methodology of current quality management and their though, conclude the theoretical method research in statics process control proposed by famous fellow in recent year; detailed illustrate related theory of the statics process control. Secondly, group technology had been used in quality control of different size products machining process. Establish the group technology Base on the R-control chart and analysis the manufacturing process ability. Then, the component analysis technique used in multi variant statics process control, T2control chart had made base on the principal component analysis. Finally this context would use six sigma management ideal apply to cold-rolled lithium aluminium alloy sheet during the machining and give suggestions to quality improvement.
