The programming of CNC gear hobbing machine involves multiple steps and parameter settings, mainly including:

1.Preparation of workpieces and cutting tools: Firstly, it is necessary to adjust the stroke length and position of the cutting tool according to the tooth width of the workpiece and the installation position of the cutting tool.

 This usually involves calculations and adjustments to ensure that the tool can correctly cut the workpiece

2. Set the number of strokes and motor frequency: Based on the average cutting speed of the workpiece and the stroke length 

of the gear hobbing tool, calculate the reciprocating stroke of the tool shaft and set the frequency of the main motor. These settings affect the speed and efficiency of processing.

3. Choose a split tooth gear: Based on the balance formula of the split tooth rolling motion and the existing 

number of gear teeth, select the appropriate installation method for the split tooth gear and the number of teeth for each gear. 

This step is crucial for ensuring machining accuracy and balance.

4.Set the circumferential feed rate: Determine the circumferential feed rate based on the hardness, modulus size, desired accuracy, and roughness

 of the workpiece material. This parameter directly affects the quality and smoothness of the processed surface.

5. Tool adjustment: Depending on the actual situation, choose the radial or diagonal tool adjustment method to ensure that the tool can correctly

 follow the shape of the workpiece for cutting during the machining process.

These steps require technicians to perform detailed operations and adjustments based on specific workpiece requirements and machine performance. In the programming process, it is also necessary to consider the safety of the machine tool and the convenience of operation to ensure the efficiency and safety of the machining process.
