英文摘要：

A new precision forming technology was presented, which uses an ordinary forging machine and a high precision rotary forging machine to make the closed-tolerance semi-axle bevel gear forgings. A series of key technical issues were researched, including blank shape in forming step, process param- eter of forming process, structures Of forging die and machining fixture, etc. The closed-tolerances and high strength of gear teeth, fine quanlity of meshing, high life time of dies, high availability of material, lower cost and massive production are achieved by using the forming technology.
