The Design And Manufacture Of Abrasives Process Quality Control System Based On

Since twenty-first Century, with the development of science and technology changerapidly, as well as the global market competition is fierce day by day, the quality of productshas become the influence enterprise vitality and brand market share the key factors. Manydomestic abrasive production enterprises are still widely used traditional after inspectionmethod, not only the production cost is high and has not been able to meet customer andmarket demand. In addition, with different mechanical products, abrasive production processhas its own characteristics, such as mixing, molding processes are not reversible process, onceappear waste to rework. This requires more application" to prevent" the advanced qualitycontrol methods can effectively reduce the reject rate, while ensuring product quality tocontrol the cost.Based on the comprehensive analysis of the present stage of quality control of internaland external research and development on the basis of the status quo, mainly resin Abrasivesmanufacturing process design as the research object, modern quality engineering technologyas the guide, for design and manufacturing process quality control system based on. The maincontents include the following:In the grinding process of product design, based on the quality function deployment(QFD) method, using the" house of quality" level, customer requirements and its importanceinto the grinding quality characteristics, design requirements, process parameters and otherinformation, enables the designer to improve customer satisfaction as the ultimate goal inabrasives line design. And “design--Test--improved" this passive traditional product designmode is changed into an active, prevention product design model.Resin abrasive manufacturing process, with statistical process control (SPC) theory, themixing uniformity, molding hardening process of number of rejects, finish machiningdimension after several index as the control object, the use of SPC control chart on resinabrasive machining process quality fluctuation to monitor, if it is found that the process is inabnormal trend, should be timely to find the reasons, to take measures to reduce the qualityfluctuation. It can be as much as possible without changing the original production process and reduce scrap rate. The process capability is calculated and analyzed, in order to guaranteethe processing capacity based on cost control.In the above two aspects of the basis of theoretical research, application of VisualBasic6.0and SQL Server2000as a development platform, the development of computeraided quality control system, the resin Abrasives manufacturing process design qualityinformation management, realize the resin formulation design and process quality control anderror diagnosis.
