As a basic study for the establishment of the methodology for computer aided or automated design of machine structures, this report deals with an algorithm and a computer program for the automated generation of the skeletal structures of the motion transmitting systems of power transmitting or motion transmitting machines, such as machine tools and measuring apparatuses. The motion transmitting systems of the machines are considered as an aggregation of motion transmitting elements, such as gear mechanism, screw driving mechanism and cam mechanism, and their skeletal structures are generated automatically using their functional structures, the algorithm and the application results were explained in the second report of this study. Some results for machine tools are presented, which were generated by the implementation of this computer program.
