金属PM塑性成形技术是指金属在进行塑性成形时，除给工件加正压力（P）外，同时再施加一定的扭转力矩（M），由于PM复合加载同时作用在制件上，可以极大地提高工件塑性变形程度，并且大大降低工件变形力，这种变形方法称之为PM塑性成形。金属PM塑性成形技术是一种新工艺，而实 Metal PM plastic forming technology refers to the metal in the plastic forming, in addition to the workpiece plus pressure (P), while applying a certain torque (M), due to the PM composite load acting on the workpiece at the same time, you can greatly Improve the degree of plastic deformation of the workpiece, and greatly reduce the workpiece deformation force, this deformation method is called PM plastic forming. Metal PM plastic forming technology is a new technology, but real
