Depending on the movement of the forging die, forging can be divided into pendulum rolling, pendulum swivelling, roll forging, wedge rolling, ring rolling and slant rolling. Pendulum rolling, pendulum swivelling and ring rolling can also be used for finishing forging. In order to improve the utilisation of material, roll forging and cross rolling can be used as a pre-process for slender materials. Rotary forging, like free forging, is also partial forming and has the advantage that it can be formed with less forging force compared to the size of the forged part. In this type of forging, including free forging, the material expands from the vicinity of the die face to the free surface during processing, so it is difficult to ensure accuracy. Therefore, the direction of movement of the forging die and the rotary forging process are controlled by computer, so that products with complex shapes and high accuracy can be obtained with lower forging forces, for example, the production of forgings such as turbine blades with many varieties and large sizes.
