A prototype cam-follower mechanism was designed and assembled using Pro-Engineer (Pro-E) software. The mechanism is meant for application in a forth-and-back Mode II Operation of a tribotester rig. The mechanism was dynamically simulated in Pro-E to ascertain the dynamic loading status of integral parts. CES EduPack software was applied to select the best material for the spring using the Function-Objectives-Constraints approach. Candidate materials were first screened using design constraints after which shortlisted materials were ranked using design objectives. The final material choice made with reasonable trade-offs was found suitable for intended service environment requirements.
