Gear hobbing and hobbing are commonly used methods in gear machining, each with different characteristics and application scenarios. The following is a detailed introduction to these two gear processing methods:

Insert teeth. This method mainly uses a gear hobbing cutter for machining on a gear hobbing machine, and can be used to make internal gears, external gears, or racks. The principle of gear shaping is equivalent to the meshing of a pair of straight cylindrical gears, and the gear shaping cutter is actually a gear with cutting edges.

Rolling teeth. This method uses a hob to machine gears, which is equivalent to a pair of intersecting helical gears meshing. Gear hobbing can be seen as the transmission of gears and racks without meshing clearance, forming the involute tooth profile of the workpiece through the continuous transmission of the hob.

Both of these methods belong to the generative method, which simulates the motion of gear meshing to machine gears, but they differ in tool design, machining principles, and applicability.
