CAD/CAM System for Cylindrical Cam Mechanism of Adjusting Device in Disposable Sanitary Products Production Line

Combining cylindrical cam mechanism with oscillating follower used in adjusting device in the disposable sanitary products production line, in view of the technical problems of cylindrical cam design and manufacture, according to the equation of profile surface of cylindrical cam with oscillating follower, the toolpath equation of unequal diameter machining was derived based on double envelope principle. And in accordance with Boolean calculation and generation method and redevelopment interface for 3D software, the precision 3D parameterization modeling and CAD/ CAM system of cylindrical cam were realized. The application results showed that the system could accurately process the cylindrical cam in adjusting device, and the cost was low. The development of the system could effectively improve the efficiency of the design and manufacture of cylindrical cam.
