摘 要：

众所周知，健康一直是人类永远的追求，也是人类最宝贵的财富。随着医学技术的发展，各种各样的人造器官开始出现，人工关节是人们为挽救已失去功能的关节而设计的一种人工器官，它在人工器官中属于疗效最好的一种。一般来说，其使用年限可达20年以上。它可以即刻消除关节疼痛、恢复关节的正常活动功能，使长期受关节病痛折磨的人们再次获得新生，手术后可以象正常人那样，行走、爬楼、外出旅行、外出工作、购物和体育锻炼等。目前我国的制造水平和国外还有着很大的差距，人工关节行业几乎被国外的XX公司，史塞克等公司所垄断。因此，我国急需快速追赶和超越。此次我的课题是关于人工肩关节的制造，主要是根据产品的模型进行加工工艺的制定、编写数控程序，利用数控车床进行加工来确保产品规格的精确性，最后通过喷砂、抛光等一系列后道工序来完成人工肩关节的制造。

Abstract

As we all know, health has been the eternal pursuit of mankind. By a variety of different organs of the body composition of any one organ lesions or damage will bring pain. With the development of medical technology, a variety of artificial organs began to appear, Artificial joints is an artificial organ to save the people have lost the function of the joints and design, it belongs to the best kind of efficacy in artificial organs. In general, their useful life up to 20 years. It can instantly eliminate joint pain and restore joint function of normal activities. People affected by long-term joint pain and suffering will be reborn. They can be as normal as walking, climbing stairs, travel, go to work, shopping, and physical exercise after the surgery. At present, China's manufacturing standards abroad have the very big disparity, artificial joint industry almost monopolized by foreign Johnson, Stryker corporation. At present, China's manufacturing standards there is a large gap and foreign country 's ,artificial joint industry almost monopolized by foreign Johnson & Johnson, Stryker and other companies. Therefore, China's urgent need to quickly catch up and surpass. My task is about manufacture of artificial shoulder joint.According to the model of the product development process, the preparation of NC program, the use of CNC lathe processing to ensure the accuracy of product specifications. Finally, to finish produced by sandblasting and polishing after a series of processes.
