The working principle of a gear hobbing machine mainly includes the following aspects:

1. Mechanical motion gear hobbing machines are usually composed of motor transmission system rails and sliders. The motor provides power transmission system to transmit the speed and torque of the motor to the guide rail and slider, which are responsible for moving the cutting tool onto the workpiece.

2. Cutting force: During the cutting process, the cutting force exerted by the cutting tool on the workpiece needs to overcome the resistance of the workpiece material in order to cut out the tooth groove.

3. Workpiece positioning: Workpiece positioning refers to placing the workpiece on the gear hobbing machine and ensuring its position is accurate and error free. Workpiece positioning is usually achieved through fixtures or positioning devices.

4. The movement of the slotting tool: The slotting machine drives the tool holder and worktable through a transmission device to perform corresponding movements, allowing the slotting tool to enter the tooth groove position of the gear. In the process of gear shaping, the blade of the gear shaping tool cuts the gear through cutting force, and the tooth groove is machined out

5. Feed rate and tooth depth of gear shaping tools: The feed rate and tooth depth of gear shaping tools can be controlled by adjusting the transmission device to meet the requirements of gears.

6. Principle of gear shaping cutter: The gear shape used in the gear shaping machine is similar to a pair of cylindrical gears that mesh with each other. The rotational motion of the slotting cutter and the rotational motion of the workpiece form a composite motion - generating motion, forming the involute tooth profile of the workpiece, and the reciprocating motion of the slotting cutter forms a wire in the direction of the workpiece tooth length.

Overall, the working principle of a gear hobbing machine is to gradually insert the tool into the workpiece through the relative motion between the rotating tool and the workpiece, forming a tooth groove, while ensuring cutting safety and accuracy.
