SCIENCE AND TECHNOLOGY ENGLIAH FOR MECHANICAL ENGINEERING LESSON SIX GEAR MANUFACTURING METHODS There are two basic methods of generating process manufacturing gear teeth, the展成法 generating process and the forming forming process process. When a gear tooth is 成形法 generated, the workpiece and the grinding磨削 cutting or grinding tool are in continuous mesh and the tooth form ismesh啮合,网格 generated by the tool. In other word the work and the tool are conjugate to conjugate共轭的 each other. Hobbing machines, shaper cutters, shaving machines, and many‖ hobbing滚削,滚刀 grinders use this principleSCIENCE AND TECHNOLOGY ENGLISH FOR MECHANICAL ENGINEERING LESSON SIX GEAR MANUFACTURING METHODS There are two basic methods of manufacturing gear teeth, the generating process and the forming process.
