Research on Integrated Quality Control in Product Manufacturing Stage

In view of the weak quality control in manufacturing process, the lack of data support in decision planning layer and management control layer, this paper analyzes the operation flow and quality data link of datadriven product manufacturing quality integrated control business operation process and quality data link, studies the multi-process manufacturing process quality integrated control method, realizes the machining error and quality dynamic control between multi-process in complex parts manufacturing process, improves the machining precision and efficiency of parts, puts forward the dynamic control method of machining process quality for component assembly, establishes the relationship between complex process capability index and matching degree, and realizes the prediction analysis and optimal matching of assembly results, effectively improve the assembly quality and assembly efficiency of precision components.
