Research Of Quality Insurance Technology For Cooperative Manufacturing Technics

Based on shop manufacturing technics, capacity of equipment, process tolerance and process status which are primary quality characters together with relative manufacturing quality elements were difined and evaluated in this dissertation.Correlations of quality elements and quality characters were deciphered and analyzed. By arithmetical aparting of manufacturing tolerance and measuring tolerance, process quality variation was analzed and its effects controlling method was offered. Genetic Algorithm(GA) method and Respondance Surface method(RS) were introduced for optimizing of quality characters. TRIZ method was also introduced for solving of process quality confliction and σ decompounding according to 5M1E was for quality programming.Process quality was evaluated benching quality cost,quality stability and k σ statistical quality control:Quality Function Deployment method was used for the layout of process quality and process quality forecasting model based on nerve-net structure using Back Promulgation(BP) arithmetic was discussed.For cooperative manufacturing,closed loop quality control model,quality insurance workflow process model.quality insurance workflow structure mode! and web-based cooperative quality control workflow model were offered in this dissertation.
