Development of an integrated CAD/CAE/CAM system on taper-tipped thread-rolling die-plates

This paper describes the research on an integrated CAD/CAE/CAM system for constructing thread-rolling die-plate geometry. The development of a thread-rolling die-plate is very time-consuming, since the trial-and-error method is the norm in the site test incurring unavoidable unproductive time. Furthermore, the die-plate geometry varies when the geometry is rectified on the shop floor and documentation is poor. An industrial example was adopted to verify the integrated CAD/CAE/CAM process and has demonstrated very encouraging results, showing the feasibility of the system towards industrial application. The system can be adopted to enhance the thread-rolling process integration for the screw production industry in Taiwan.
