The programming process of CNC gear hobbing machine mainly includes the following steps:

Preparation work. Determine the model, diameter, number of teeth and other parameters of the workpiece to be processed, and calculate the radial and axial offsets of the gear shaping tool.

Set the coordinate system of the machine tool: Determine the coordinate system based on the machining process and machine structure of the workpiece. The coordinate system of the CNC gear hobbing machine is divided into absolute coordinate system and relative coordinate system.

Establish a workpiece coordinate system. Establish a workpiece coordinate system based on the shape and processing technology of the workpiece, and determine the origin and positive direction of the axis.

Select the gear shaping tool and cutting parameters. Select appropriate gear shaping tools and cutting parameters based on the shape and process requirements of the gear shaping workpiece.

Write a gear insertion program. Write the gear hobbing program according to the programming specifications of the gear hobbing machine, and use G code and M code for control.

Simulate and debug. Use CNC simulation software to simulate and debug the pre written gear hobbing program, ensuring its correctness and feasibility.

Automatic processing. Upload the written gear hobbing program to the gear hobbing machine and use the machine control system for control to achieve automatic machining.

During the programming process, it is also necessary to pay attention to the setting of the tool radius, taking into account tool wear and setting errors,

To ensure the accuracy and efficiency of gear insertion. In addition,

The parameter setting of gear teeth is the most crucial step in programming,

Including information such as tooth pitch, tooth width, tooth height, and tooth tip shape

Calculations need to be made based on the specific requirements of the workpiece. The writing of machining paths is also an important part, as it defines

Determine the motion path and machining sequence of the machine tool. It is necessary to plan the machining sequence reasonably based on the shape of the workpiece and the parameters of the gear teeth.
