The basic parameters of include the following aspects:

The nominal diameter of the dividing circle. This is an important parameter of the gear shaping cutter, which determines the size and applicability of the tool. According to the national standard GB/T 6081-2001, there are multiple standard values for the nominal indexing circle diameter of spur gear cutters, such as 25mm, 38mm, etc. These values are applicable to gear machining of different sizes.

Module (m). Module refers to the ratio of the distance between adjacent teeth on a gear to π, which determines the size and strength of the gear. There are multiple standard values for the modulus of spur gear cutters, such as 1.00, 1.25, 1.50, etc., to meet the machining needs of gears of different sizes.

The number of teeth refers to the number of teeth on a gear, which affects the gear's rotation ratio and torque. There are also standard values for the number of teeth on spur gear cutters, such as 26, 20, 18, etc.

Tool diameter, tooth tip circle diameter, and tooth height. These parameters further define the specific dimensions and shape of the gear shaping cutter.

Spiral angle. The helix angle is an important parameter of the gear shaping cutter, which affects the cutting performance and strength of the tool.

Center distance. Center distance refers to the axial distance between two phase fittings, which has a significant impact on the selection and use of gear cutters.

The above parameters collectively determine the performance and applicability of the gear shaping cutter. In practical applications, selecting a suitable gear shaping cutter requires consideration of the specific parameters of the gear, machining requirements, and the ability of the machine tool.
