The Application Of Six Sigma Management In Z Project Quality Improvement

Six sigma quality management is a kind of can achieve customer satisfaction andthe maximum benefits of system science, mainly by reducing product qualityfluctuation and constant innovation, make its reduced to three over one million of apoint four fraction defective product quality defects.With the technology of Chinese aviation industry is basically stable andperfect, In the continuous development of the market of global aviation industrystrategy, enterprises of China to obtain sustainable development, we must strengthenthe process control, reduce internal consumption, to take the lead in the costmanagement and control, so the quality control is very important here.Six sgmaquality management is based on product market demand emerge as the times require,China aviation industry group as the machining of the leaders in the field, andpromote the application of Six Sigma theory.China aviation industry group as the world’s top500enterprises, enhance theircore competitiveness, to strengthen quality control, especially important is to satisfycustomers in terms of cost, quality and quick response demand.Therefore,Changhang hydraulic controlled companies actively promote the Six Sigmamanagement, has made great economic benefits, raising the potential customersatisfaction. The Z project is a new R&D project CNAC fluid control company ispromoting the host plant, due to mission requirements, the node is urgent, thedefective rate is high, not only cause customer dissatisfaction, but also reduces muchof the company’s profits. So, through the application of Six Sigma, qualitymanagement to achieve quality improvement is very urgent.Methods using the Six Sigma quality management improvement, through to theZ project of the production process and quality related problems by fishbone diagram analysis, confirmed the main quality problems caused by theproject yield low processing methods for the problem. In view of the negativeitems should improve from the improvement methods, in accordance with theSix Sigma DMAIC five steps to improve the methods of imple mentation, in thedefinition phase (Define) to set up internal project team to improve, benefit cost analysis improvement project, and confirm the improvement project duration. Because ofthe improvement of measurement process mainly through the testingpersonnel using special equipment inspection, there forein the measurementphase (Measure) were standardizeed operation training on themeasuring staff, determining the detection personnel are qualified, qualified measuremen tsystem. In the analysis phase (Analyze), first should be the failure modeand improvement plan (FMEA) two analysis methods, analyzes the causes of productprocessing method is not reasonable, risk priority number one finalinspection section (RPN) is the highest, so, should strengthenthe inspection personnel according to the processing method of positiondetection ability in the training and improvement the pre assessment; in partsmachining process, all contact with the part hole section of the risk prioritynumber (RPN) was relatively high, which is the emphases of process control andimprovement. In the improvement phase (Improve) mainly based on theabove are possible causes are analyzed, to formulate the corresponding improvementmeasures, at the same time, determine the responsible person should be qualityrespectively supplier improvement department, technology department andproduction department manufacturing project person in charge, the improve mentiscompleted and verified the time for the end of the year.In the controlstage (Control) is the main standard to improve the stage measures, to ensure thesustainability of its improvement. Through the internal processimprovement, process the project of non-performing rate decreased from9%to0.5%, annual savings of rework, scrap materials costs and rework labor costs about130000. At the same time of external factors in Z project to carry on theanalysis, from the quality control, supplie rcontrol client bad product into these twoaspects of work along both lines, in order to reduce the impact of external factors, to reduce the adverse. The project has achieved good economic benefits, atthe same time, the rate of good product improvement to meet customer deliveryrequirements, improve customer satisfaction, six sigma project management methodsof the accumulation of knowledge and experience in the company to further promote。...
