CAD/CAM of cylindrical cam mechanism based on reverse engineering technology

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.
