Quality Management Of K-Series Engine Cylinder Block Production Line Expansion Project

Cylinder line expansion project is one of the important subprojects of K series engine expansion project. It requires high quality, short time and strict budget control. As one of the most important part in the project, how to effectively carry out the quality management determines the success of the project.The dissertation firstly describes the principle of project quality management with characteristics, to analyze its particularity and complexity and the status in the implementation process of the project quality management. Then, the tolerance issues in turning moment are taken a case to illuminate the importance of quality management in project. In the case, methods and tools of quality management control and fishbone diagrams are used to find the problems occur from the technology, equipment, parts and personnel aspects. Data analysis and testing, in the last, help seek out the causes from the technique and machinery, come up with corrective measures, and improve the machinery in manufacturing and maintenance with PDCA.The cylinder line expansion project quality management is significantly improved via the case analysis and testing with the application of quality control methods and tools. The requirements of project quality are completely met and the plan is prospectively finished, which creates great value for the project quality management in future products.
