Outline of Final Research Achievements

Simulation technologies for NC machine tools to realize advanced virtual factories are developed in this study. They are, a simulation technology to predict the influence of dynamic and geometrical error sources onto the machined workpieces, a simulation method for the energy consumption during the motions, and a coupled simulation technology between the dynamic machine tool behaviors and cutting forces. Those technologies can be integrated as a virtual machining center. Actual machining and measurement tests are carried out to evaluate the developed simulation technologies. It is confirmed that the developed virtual machining center can predict the behaviors of actual machine tools. It is expected that the developed virtual machining center can be an effective tool to optimize the machine tool design, cutting conditions, and production processes.
