Gear machining based on generation method

The working principle of a gear hobbing machine is based on the generation method for gear machining.

 It uses a gear cutter to generate motion by meshing with the workpiece according to the meshing relationship of the gear pair,

Make the workpiece tooth surface enveloped by the cutting edge of the tool. The machining principle of a gear

 hobbing machine is similar to that of a gear hobbing machine, both of which adopt the principle of generation. However, the gear hobbing cutter is driven by meshing relationship,

Simultaneously perform up and down movements to avoid scratching the surface of the processed workpiece. 

During the idle return stroke of the gear cutter, there must be a way for the cutter to move, and at the beginning of the working stroke, the gear cutter (or workpiece) must return to its original position.

The gear hobbing machine can process both external and internal gears, as well as gear blocks with steps, 

herringbone gears, and segmented gears. The ability to process internal gears is a prominent feature of gear hobbing.

The structure of the gear slotting machine allows the cutting tool to move back and forth while also being able to rotate, 

while the working principle of the slotting machine is similar to that of the gear slotting machine, which operates vertically, but it can only perform reciprocating motion.

In addition, although there are commonalities between gear hobbing machines and planers, such as similarities in 

machining principles and machine tool movements, there are also differences between them. For example, the cutting tools of gear hobbing machines are gears,

The cutting tool of the gear planer is only a tooth groove on the generating gear (shaking table). These differences make the two types of machine tools unique and applicable in gear machining.
