Abstract: Twist-compression forming is a process that a pressure is exerted along the height direction of the workpiece, and at the same time, a twisting torque is exerted along into cross-section direction during the process. It can change the harmful effect of friction for the useful one, reduce the deformation force and improve the structure of forging. Whole process is studied by numerical simulation and in some experimental methods.
