The synthesis of motion laws for cam mechanisms with additional movement of the follower

The research discusses the design of cam mechanisms for special purposes. The analysis of the scientific literature on this issue indicates that at present the synthesis of the cam mechanisms motion laws is carried out mainly using a standard set of acceleration curves or displacements. In some cases, the designer needs to synthesize an acceleration law which should be task-specific and provide for a certain production step. Additional areas on the cam profile which perform specified motions of the follower are very important for the synthesis of such mechanisms. There may be several areas of this type. The relevance of the study is due to the fact that the mechanisms that work using a time-compressed cyclic diagram cannot be modernized on the basis of the existing methods for the synthesis of cam mechanisms; therefore, it is not possible to enhance the performance of such mechanisms without a significant change in the laws of motion.
