CAD/CAM system of cylinder indexing cam mechanism based on VB and Creo

According to the theory of cylinder indexing cam mechanism, based on the modular design, the CAD/CAM system of cylinder indexing cam mechanism is developed by VB6.0 and Creo3.0. This system is a visual interface which is build by VB6.0and it can be used to output the three-dimensional coordinate data and processing date of the cylinder indexing cam through the basic parameters input of cam and the choosing of motion law for cam follower. Then this system can save the date file as the format of”.ibl". After that, the file is imported into Creo3.0 to generate curve and surface. At last, the solid model of the cam is obtained by merging the surface and removing the theoretical profile surface. The practicability and convenience of the system are verified and the design and machining efficiency of the cylindrical indexing cam are greatly improved.
