Study Of Production Process Quality Control Of The P-Aero-engine Of The LM Corp

Quality is very important for production. Quality is affected by all kinds of factors in enterprise production and managements, is reflection of enterprise all kinds of works integrated. To ensure and improve product quality, we must manage all infection quality factors. Quality control is a suit of quality control system, means, method systemic management activities for enterprise ensuring and improving product quality. It is said concretely, organizing enterprise staff and relational departments together use modern science and management technical production, controlling product quality all process and others factors, research economically systemic management activity for produce and providing satisfaction product for user.Quality Management and the emergence of quality assurance standards has its profound historical background, it is the quality of management development to a stage of the logo and product. Mechanical products for the production process, in order to increase energy, improve product quality, often to study the production of advanced flow control and advanced control products are usually the target of quality indicators, namely, product quality control issues. Aero-engine Product development cycle length, technical difficulty, cost of funds, and therefore, the quality of aviation products are very important, an aero-engine products, good or bad, directly related to the production process quality control.This author summarizes the dawn of the quality control of the engine problems in the recent years, giving the production process quality control system architecture, researching and exploring the production process quality control and its realization process, and optimized control. The main contents as follows:(1) In this paper, through the use of causal analysis diagram from the person, machine, material, method, ring several factors affecting the quality of analysis, identified the main factors affecting quality, against the failure processing part of the scene was investigated Products through data analysis and graphics that affect the quality of questions has been a major factor. According to the production characteristics of the machine oneself product of the aviation, to circulate with service the process proceed the process control plans, process ability analysis, the process guarantees ability research etc, making product quantity variation been placed in the acceptation of the level. Base the proceeding many variation analyze, finding out the main variation reason of affecting the main factor of the quantity, proceeding to each process the analysis study, finding out the biggest factor that affect the product quantity, making sure the control point. According to the key quantity characteristic of the product and affect the domination process factor of these characteristics, to identify the procedure that ruled the movement with the standard of the control, from attaining the blemish prevention, reduce the mistakes and wasted. The unqualified product that aimed at parts of processes inside proceed the inquisition, passing the data analyze to mean with sketch, getting the problem that affect the main factor of the quantity.(2) According to the machine production characteristics of the aviation, designed from the beginning of spare parts diagram till the last of the product hands over the soldier-check, being in the light of check top work preface, service bottom work preface of three work prefaces produce the request, to design, manufacturing, assistance produce, usage the quantity of the process management set out to proceed an each control point for concrete production line flow chart, and to production line the analysis. Being passed exploitation arrange diagram, control diagram and so on ,quantity control tool to production data proceed statistics the analysis, proceed the research from second factor to the main factor that affect the quantity, certain influence the special work preface of the quantity factor, and as to it's proceed the concern with control. Through the use of maps, control charts, such as quality control tools for the production of data for statistical analysis, the main reason affecting the quality and non-owner to carry out research to identify the specific methods to improve quality, to quality provides the basis for the continued improvement. Through the analysis of process equipment and personnel, the impact of environment on the quality, the use of the establishment of quality control, introduction of "quality inspection record card" by means of the production process for each and every aspect of strictly controlled.(3) To the production process to optimize the quality control program, part of the scene for processing unqualified products were investigated through data analysis and graphics that have been the main factor affecting quality analysis and reason. In the product with the standard drawing, meaning with can trace back to the procedure to rule the coding rule of the qualified certification accurately, and the district marking of the finished product request. Install from the need in the aspects of keeping watch on with measure the equipments management control procedure the plan, supplier choice( CMC marking), contract management, marking management, period examines, unqualified control, the equipments reforms, seal to save the management and discard the provision that management etc. proceeded the point considers. In measure system analysis control procedure aspect to each diagraph with experiment equipments system have to out of result of become bad, proceeding to statistics the research, repeating to the tool and emersion research and to result take into the analysis, evaluation, combine to the analysis and evaluation report. Putting paid to quickly unqualified article and suspicious products in the aspects of unqualified article of controlling the procedure, to make evaluation with handle, in order to prevent the repetition the unqualified article that appear proceeds the further reason analyzes, and through to rectify with prevent the measure, prevent the unqualified article to take place the proceeding the detailed design again, and put forward the production line quantity improve whole to change the measure with method. Controlling of nonconforming product procedures carried out a detailed design and to make the production process of quality improvement methods, measures and methods of rectification.
