Cam mechanisms are widely utilized for automatic devices in production lines, and the important influences for accuracy of out motions are the kinematic characteristics of follower motions. In order to realize and analyze the influence of the error in manufacturing processes, this research is going to analyze the planar cam-follower motion curve by using the reverse function in a measuring system. The goal of this research is to improve the measuring accuracy and efficiency in a cam measuring system. Results obtained by applying the developed measuring system also compared to those obtained by using a coordinate measuring machine.
