[摘要] Mastercam是用于机械行业中计算机辅助设计及制造（CAD/CAM）的软件系统，它是基于PC机并为机械零件的二维与三维设计提供全方位优良环境，可以实现仿真加工。最重要的特点是它能输出所设计零件的原始数控程序代码（CNC）。本文基于Mastercam软件，首先对支架进行三维造型，然后利用Mastercam对支架仿真加工，主要的研究方向是支架的加工工艺。加工工艺设计好以后，在Masteream平台上生成加工代码。
论文在分析综述了Mastercam性能、特点的基础上，系统的阐述了支架造型方法和步骤，完成支架的造型。在分析了所要仿真加工的支架的形状后，针对不同的加工面相应的加工方法，选择了合理的加工工艺。本文还对不同的加工工艺做了比较，通过比较可以看出，本文中选取的工艺参数和工艺路径是合理的，这对提高加工质量有一定的实际意义。

Machining process design and simulation
[Abstract] Mastercam is used in the machinery industry of computer aided design and manufacture (CAD/CAM) software system, which is based on PC and mechanical parts of 2 d and 3 d design provides the omni-directional good environment, can realize the simulation processing. The most important characteristic is that it can output the designed parts of the original numerical control (CNC) program code. Based on Mastercam software, scaffolds for three-dimensional modelling in the first place, then use Mastercam for stent simulation processing, the processing technology of the main research direction is support. After machining process design, generating nc code on Masteream platform.
Paper on the basis of analyzing the Mastercam properties were reviewed, the characteristics, the system elaborated the stents modelling methods and steps, to complete the modelling of stents. Based on the analysis of the simulation processing by the shape of the scaffold, according to different processing and surface processing methods, choose the reasonable processing technology. This article also made a comparison of different processing technology, through the comparison, you can see that in this article, the selection of process parameters and process route is reasonable, it has certain practical significance to improve the processing quality.
