Mold Machining Process and Applying Technologies of Spiral Bevel Gears

摘要

Mold processing had been the main method of the fast development in modern industry and production, which was the way to accelerate producing efficiency and reduce the cost. The performance and accuracy was the key to realizing molding processing of spiral bevel gears. In traditional, EDM(Electrical Discharge Machining) was used in manufacturing spiral bevel gears mold, which led to low precision for large processing error in the tooth surface of electrodes. Then surface accuracy and meshing performance couldn't achieve to the expected demands. The way of modeling by three-dimensional software became a new selection with the high surface accuracy and simple modification process to surface. There were mainly injection, powder metallurgy, precision forging, die-casting and so on.
