【摘要】：超硬材料磨具(以下簡稱超硬磨具)屬于國家重點支持的新材料產(chǎn)業(yè)產(chǎn)品,被稱為“現(xiàn)代工業(yè)牙齒”,是一種高速、高效的現(xiàn)代磨削工具,被廣泛應(yīng)用于航天航空、國防軍工、電子信息、汽車制造、機床工具、能源交通等精密加工領(lǐng)域。我國雖是超硬磨具生產(chǎn)大國,但由于其多品種、小批量、定制化的生產(chǎn)特點,且大多為勞動密集型手工作業(yè)的制造模式,超硬磨具生產(chǎn)質(zhì)量穩(wěn)定性差,產(chǎn)品不能完全滿足精密加工需求。因此,開展超硬磨具生產(chǎn)過程的質(zhì)量風(fēng)險管理研究有十分重要的現(xiàn)實意義。論文從我國超硬磨具企業(yè)管理者的角度出發(fā),試圖找出有效解決超硬磨具生產(chǎn)過程質(zhì)量風(fēng)險問題的管理方法和措施,以提高產(chǎn)品質(zhì)量,切實降低超硬磨具生產(chǎn)過程的質(zhì)量風(fēng)險,注重提高質(zhì)量管理人員質(zhì)量風(fēng)險意識,能夠有效促進超硬磨具生產(chǎn)企業(yè)質(zhì)量管理水平,提高產(chǎn)品質(zhì)量穩(wěn)定性,為產(chǎn)品“走出去”提供可靠質(zhì)量保證。論文首先對公司近兩年的質(zhì)量事故記錄進行統(tǒng)計分析,得出有記錄的質(zhì)量事故列表及其發(fā)生概率;然后利用歷史文獻和專家知識,結(jié)合調(diào)查問卷結(jié)果初步得出超硬磨具生產(chǎn)過程質(zhì)量風(fēng)險因素清單,并根據(jù)經(jīng)驗值對事件發(fā)生次數(shù)進行排序,通過專家討論修訂質(zhì)量風(fēng)險因素清單和排序;最后將有記錄的質(zhì)量事故發(fā)生概率填入排序表中,根據(jù)排序相近概率相近原則,通過專家討論,對質(zhì)量風(fēng)險因素清單和發(fā)生概率進行最終修正。根據(jù)質(zhì)量風(fēng)險因素清單,運用故障樹分析(FTA)方法,對超硬磨具生產(chǎn)過程質(zhì)量風(fēng)險進行識別,并進行定性和定量分析,得出加工、裝卸和轉(zhuǎn)運過程中造成的磕碰、員工看錯圖紙和模具上壓頭間隙大等因素是超硬磨具生產(chǎn)過程的主要質(zhì)量風(fēng)險因素,通過建立質(zhì)量管理人員能力需求模型,對人員類質(zhì)量風(fēng)險因素提出管控要求,并提出方法類質(zhì)量風(fēng)險因素的改進思路。通過超硬磨具生產(chǎn)過程質(zhì)量風(fēng)險管理研究,能夠使制造企業(yè)更加精準(zhǔn)地識別質(zhì)量風(fēng)險因素,并進行有針對性的分析、評價和應(yīng)對。從而提高超硬磨具生產(chǎn)過程的質(zhì)量風(fēng)險管理水平,進一步增強產(chǎn)品競爭力。
[Abstract]:Super hard material grinding tools (hereinafter referred to as superhard Abrasives) belong to the national key support new material industry products. They are called "modern industrial teeth". It is a high speed and efficient modern grinding tool. It is widely used in aerospace, defense industry, electronic information, automobile manufacturing, tool tools, energy transportation and other precision processing fields. The production of super hard abrasive tools is a big country, but because of its many varieties, small batch and custom-made production characteristics, and most of them are labor intensive handwork manufacturing mode, the quality stability of super hard abrasive tools is poor and the product can not fully meet the demand of precision processing. Therefore, it is very important to carry out the research on the quality risk management of the production process of the super hard abrasive tools. In order to improve the quality of the product, reduce the quality risk of the production process of the super hard abrasive tools, improve the quality risk awareness of the quality management personnel and be able to improve the quality risk awareness of the quality management personnel, the thesis will be able to improve the quality risk of the quality management personnel. It can promote the quality management level of the super hard abrasive production enterprises, improve the quality stability of the products and provide reliable quality assurance for the product "going out". First, the paper makes a statistical analysis on the quality accident records of the company in the last two years, and draws a record of the record of the quality accident list and its occurrence probability; then, the historical documents and the expert knowledge are used. According to the results of the questionnaire, the list of the quality risk factors of the production process of the super hard abrasive tools is obtained, and the number of events is sorted according to the experience value. The list and order of the quality risk factors are revised by expert discussion. According to the list of the quality risk factors and the probability of occurrence, according to the list of quality risk factors, the quality risk of the production process of super hard abrasive tools is identified by the method of fault tree analysis (FTA), and the qualitative and quantitative analysis is carried out to get the knock in the process of processing, loading and unloading, and the employees are mistaken in the drawings and models. The main factors such as the high pressure head clearance are the main quality risk factors in the production process of the super hard abrasive tools. By establishing the model of the quality management personnel's ability demand, the management and control requirements are put forward on the quality risk factors of the personnel, and the improvement ideas of the quality risk factors of the methods are put forward. The manufacturing enterprises identify the quality risk factors more accurately, and carry out targeted analysis, evaluation and response, thus improving the quality risk management level of the super hard grinding process and further enhancing the competitiveness of the products.
