Reverse Design of Cam Mechanism

A data analysis method caused by manufacturing error in reverse design of on-off pressure cam mechanism of offset press was presented. The theory profile of cam can be inferred from the measurement data of actual cam profile according design theory of cam. Application for the numerical analysis method, angular displacement and analogy acceleration of cam follower can be obtained. Compared with the data of expecting analogy acceleration, error of analogy acceleration be obtained,error of angular displacement as well. The data removed angular displacement error is closer to original design data.
