Measuring cam–follower performance

A comprehensive experimental analysis is conducted for measuring dynamic response of jerk optimized, stress optimized and size optimized cams, with advanced techniques of data acquisition and data processing. A precision manufacturing process is employed for preparing cam surface. Results show close matching of experimental outputs with theoretical predictions of displacement and values of follower preset. A method is suggested for specifying the causes behind deviations of predicted cam displacements from actual displacements.
