Abstract
This study investigates the process design method for precision forging combined with complex and flexible motions realized
using servo-press machine with the aid of computer-aided engineering technology and design of experiment study. The
evaluation results for the simplified unsetting process of a CVT pulley and precision spur gear forging process indicate that the
design method proposed in this study could provide useful information on the effects of press motion for important process
outputs, such as the forming load and deformation behavior of the workpiece.
