摘　　要：介绍了圆柱凸轮机构逆向设计与制造的流程和方法。利用三坐标测量机和Pro/E软件为平台实现辅助设计,以Microsoft Visual C++6.0为开发工具,基于Windows平台编制了圆柱凸轮机构设计与制造软件,实现了圆柱凸轮机构的循环图和轮廓设计,并可进行压力角及曲率半径的快速校核和凸轮的运动仿真,生成了直接用于数控机床的刀具NC加工代码,实现了圆柱凸轮机构设计制造一体化。此CAD/CAM系统不仅可用于圆柱凸轮机构的反求设计,亦可简单快捷地实现圆柱凸轮机构的正向设计。文中以圆柱分度凸轮的反求与制造为例详细说明了基于逆向工程技术圆柱凸轮机构的设计与制造方法和流程。The paper presents a new process and method of reverse design and manufacturing of the cylindrical cam mechanism.By applying the Coordinate Measuring Machine（CMM） and the PRO/E software as the platform to carry out aided design,by taking Microsoft Visual C＋＋ 6.0 as the development tool,and based on Windows platform,the cylindrical cam mechanism design and manufacturing software is generated,allowing the design of cycle map and cam profile,checking the pressure angle and curvature radius rapidly,simulating the motion of cam.And the NC machining codes which can be directly used for numerical control machine were generated,achieving the integration of design and manufacture of cylindrical cam mechanism.This CAD/CAM system can not only be applied in the reverse design of cylindrical cam mechanism,but also used to achieve the forward design of cylindrical cam mechanism quickly and easily.Finally,by taking reverse design and manufacture of the cylindrical indexing cam as an example,the reverse design and manufacturing process and method of cylindrical cam mechanism based on reverse engineering technology has been explained in detail.
