 加工齿轮轮齿有两种基本的方法：产生过程和形成过程。当一个轮齿产生时，工件和切削或磨削工具，是不断啮合在一起的，轮齿的形式是由刀具决定的。换句话说，工件和刀具是共轭的。滚齿机，成型切割机，剃齿机，磨床都使用这个原理。
 当一个轮齿形成时，该刀具是呈正被加工出来的空间的形状的。一些磨床使用此原理，与一个指示装置配套在一起使轮齿一个挨一个形成。刀就是同时加工所有轮齿形成刀具的例子。
成型    成型本质上是与平面图类似的，但采用了圆形的切削刀具替代了齿条，由此产生的往复惯性的减少，允许更高的行程速度：现代的成型切割汽车齿轮可以以每分钟2000切割行程运行。切削刀具的形状大致是与渐开线齿轮相同的，但轮齿的顶端是圆形的。

 There are two basic methods of manufacturing gear teeth: the generating process and the forming process. when a gear tooth is generated, the workpiece and the cutting or grinding tool are in continuous mesh and the tooth form is generated by the tool. In other words, the work and the tool are conjugated to each other. hobbing :machines, shaper cutters, shaving machines, and grinders use this principle.
 When a gear tooth is formed, the tool is in the shape of the space that is being machined out. Some grinding machines use this principle with an indexing mechianism which allows the gear teeth to be formed tooth by tooth. Broaches are examples of form tools that machine all the gear teeth simultaneously.
