The manufacturing lines of the sponsoring company utilize cam129]follower systems where complex motion is required. Insight into the suitability of servomotor mechanisms as replacements for cam129]follower systems was desired. To that end, design and manufacture of a Cam129]Servo Test Machine actuated by either cam-follower or servomechanism was undertaken by the project129fs participants. The machine design employed a timing belt speed reduction in its drive train, which had an unintended deleterious impact on system stiffness. A revised design was developed and analyzed in its stead. The project team concluded that a larger servomotor, directly mounted, can be a suitable replacement for a cam129]follower system at a cost that is several orders of magnitude greater.
