The calculation of the number of teeth for the gear cutter can be determined based on the modulus and number of teeth of the gear. The specific steps are as follows:

1. Determine the modulus m and number of teeth z of the gear:

The modulus m refers to the ratio of the number of teeth z of a gear to the diameter of its indexing circle, usually expressed in metric system.

The number of teeth in a gear is the number of teeth and is also an integer.

2. Calculate the number of teeth n for the gear hobbing cutter:

The number of teeth n of the gear hobbing cutter can be calculated using the following formula: n=zm.

Where z is the number of teeth of the gear, and m is the modulus.

3. Determine whether the gear hobbing cutter is suitable:

After calculating the number of teeth of the gear hobbing tool, it is necessary to determine whether the tool meets the requirements for machining gears.

In addition, the selection of the gear shaping cutter also needs to consider other parameters, such as modulus, displacement coefficient, front angle, back angle, etc., as well as the calculation of the outer diameter of the gear shaping cutter and the selection of the shank diameter. These parameters will affect the specific size and applicability of the gear shaping cutter
