Quality Control In The Auto Slack Adjustment Assembly Production Line

After China have taken part in WTO. Many Auto international enterprise set up factories in the form of joint venture, cooperation or individual proprietorship to share the huge market during China being in high speed with our country manufactory. Being in the stage of developing and studying, we must learn from advanced management of international Auto company and keep up with the international enterprises in production and manufacturing.To win the powerful company in the competition, we must adopt the advanced management methods. We must value the application of the modern quantity, controlling technical. To survive the company must win the benefit application . whether the enterprise profit or not depend on the enterprise's economic result. So the enterprise must reduce productive cost, increase quality rate in product, benefit from management, make scientific management foundation, abandon the past management mode. The enterprise should reduce productive cost by raising quality controlling and productive quality, reduce the productive cost. The enterprises advanced technology to make more benefit.The quantity control means of the present manufacturing profession with method, most for five greatest tools that quantity control:《Advanced Product Quality Planning and Control Plan》( APQP),《Potential Failure Mode and Effects Analysis》( FMEA) ,《Production Part Approval Process》( PPAP),《Measurement Systems Analysis》( MSA),《Statistical Process Control》( SPC),《APQP》is quality that the plan that whole quantity controls the item with plans, is an ex- period the most basic ising also the most important work, is a foundation, her quality decision whole quantity controls the system.《FMEA》particularly is《PFMEA》are in quantity control system particularly for importance, if say the《APQP》is a macroscopic overall plan, so《FMEA》is a tiny view. the《MSA》and《SPC》are the verification of the method to confront deal control system inside adopt.The《PPAP》is finally, only have the verification that pass the customer with grant, the product can just realizes its value. The thesis of《Quality Control in the Auto Slack Adjustment assembly production line》is an article that writer obtains the college of science in the University of Jilin two in the last year according to putting in the knowledge of the industry engineering realm study, and Arvinmeritor FAW Sihuan (Changchun)Vehicle brake limited company establish ASA assemble linear work experience wrote of first how article is in the production line into practice quantity control.How to make use of the long joint venture company in spring establish the linear experience in assemble in ASA enhances us to make the profession quantity control will be the investigative point that this thesis want in writer.To control with the process, five greatest tool just a kind of control of means, mutually independent, at the same time with mutually support, only have to put together the organic knot in five greatest tools, attain the " three integral wholes", that is also a latent expired mode in ,《Control Plan》,《FMEA》,《Work instruction》on the core contents of unify, and continuously of the usefulness that application keep on the improvement to guarantee to control the means, at the same time according to each from the different and actual circumstance in business enterprise proceed to five greatest tools to transmute homologously, then can attain the real valid quantity with the process controlIn whole plan, firstly use of first the C2C to establish the whole item, then according to APQP to proceed the work, design. Then making《control plan》and《PFMEA》, make sure R&R request or not;The application《SPC》to proceed the worth measurement in Cpk, insuring the equipments with the accuracy that satisfy the product.Finally in produce stage of an approval,《PPAP》request hand over to customer 19 related a documents, and in the PPAP kind piece immediately the take out takes 30 samples send to customer to do the engineering test. Whole a joint effort for from adjusting arm assembly line item from the 2005 July to 2006 June, experiencing successively 12 months, passing by our item group, after establish line the quantity blemish been placed in in production line establish behind, the group again made use of wore clear wreath with method that continuously improvement, to in the actual brake process proceeds designing, the improvement that keep on, aim at every kind of quantity blemish appeared in actual production proceed the improvement, perfect control means, continuously increases the quantity of the product.For production manufacturing and particularly machine, the quantity control is particularly for importance, the among them heavy inside is《PFMEA》, aiming at latent and expired mode in process and results the analysis want to do is opposite with it should of《Control plan》《Work instruction》, making use of every kind of means exterminate possible emergence a quantity blemish is in embryoticly, this is the so-called" three integral wholes";Still make use of to wear the clear wreath at the same time to the production line improvement proceeding continuously with perfect, because plan to design regardless of have good much, in actual production because of influence that suffer to the outsider factor of every kind of each kind, the gross will appear the some unexpected trouble, so make use of the improvement that wear the clear wreath is continuously, continuously of the quantity of the product of exaltation.Fact proof" three integral wholes" is in from adjust arm assemble on-linely extremely practically, pass by in the production line continuously of improvement with《PFMEA》, the《Control plan》《Work instruction》, in subsequent half a year, we grow the joint venture company in spring to face the customer the offering totally from adjust arm 50000 reason for, its PPM is 40, unqualified pieces is 2 labels of spare parts at transport the breakage in the process, and not the blemish that is a product function.From adjust the brachial quantity suffered the customer's good opinion, this item selected at the same time the best item in beautiful the Arvinmeritor company.From the establishment of ASA assembly line, we can see, a production line wants to attain the quantity controls, we must do it for head, from the period plans to the batch quantity produces, These must have of perions details of plan with system of control, but quantity the five greatest tools is exactly most physically and effectively exactly, when at the time of using them, do not use one way , but connect the organic knot in five greatest tools together, they are mutually independent and support, APQP is basic, it through out the whole item, the FMEA is a key, working well the FMEA,to do the quantity control effectively, the MSA, SPC is a check and verify, in order to insure the accuration valid, the PPAP is an activity, finally verification, to proof our production line already in our control under, this is a big PDCA, at the same time in the working the proceeding must continuously keep on the improvement, increasing continuously our management level, reducing the error margin.This essay just I am in knowledge combination that pass college IE course high school went to in the work of some experience with experience, confront Chien of the deal control shallow an expatiates cognitively, having a lot of wrong places invite each teacher the animadversion corrects. This essay is only a summary of quantity controlling when I connect the IE knowledge with experiences, having many errors, please criticize.
