Study On Manufacturing Quality Control Of Hinge Parts

This paper compliance with the concept of"Data Driving Quality", and follows the route of"Measurement-Evaluation-Control"on Hinge Parts of manufacturing quality control, based on the traditional theory statistical process control (SPC), systemically represent a number of key issue come to the traditional theory of SPC in the actual production of the Hinge Parts and study the limitations of it.In this paper, the theory from the SPC quality control in Hinge Parts of a number of issues that exist, the method of Bootstrap will be the introduced in Hinge Parts quality control system ,in order to solve the deficiencies of traditional theory in the Hinge Parts of SPC. And doing research on traditional SPC calculatation of process capability index and boundary control set, build a confidence intervals of Bootstrap capability index, as well as solve the problems which in practice production quality control with Bootstrap Control Chart of SPC in Hinge Parts, to some extent, this has enriched the quality control of the Hinge Parts to create a theoretical system, new methods and ideas for future. It will contributing more effectively to raise the Hinge Parts on the level of manufacturing quality.In this article , he research work mainly in the following several aspects:1. It has studied the basic principle on technology of SPC and emphasis the process ability index and the control chart technology, and CHANGKONG company Hinge Parts to apply this technology, which has discovered question which existed in this enterprise application in the practical application process SPC, in the view of these questions, Bootstrap method will introduce in Hinge Parts.2. It has carried on the discussion on the QC of Hinge Parts with Bootstrap method, it has established in the Bootstrap simulation process of Hinge Parts, pointed out that this method may use in processing of the Hinge Parts detection data sampling the small sample and the non-normal distribution question. Meanwhile carried on to the Bootstrap method's use has further discussed that has given the Bootstrap process ability index confidence interval computational method as well as the Bootstrap control chart principle and carried on the key production applies.
