Calculation method for high-speed cutting parameters

Several important terms and machining parameters in high-speed cutting process
1. Cutting speed Vc
Definition of cutting speed: Vc=N * p * Deff/1000
Vc refers to the appropriate cutting speed value suitable for high-speed machining of a certain workpiece material under specific tool conditions, which refers to the linear speed of the tool.

2. Effective tool diameter Deff

3. Feed rate fz per blade

4. Axial and radial feed rates ap&ae

Calculation methods for various cutting parameters in high-speed machining

(1) Principles for setting processing parameters
1) During high-speed machining, it is necessary to optimize the machining parameters and not set them arbitrarily;
2) The cutting speed Vc value must be set correctly;
3) The feed rate fz for each blade must be set correctly.
Reasonable values can maximize the cutting efficiency of the tool, fully utilize the tool, and improve machining quality and efficiency; It will not affect the service life of the cutting tools, thus achieving cost savings and achieving the goal of truly high-speed machining.
(2) Processing testing
The testing tool used in this experiment to test its ability to cut S136 is as follows:
1) Diameter: 10mm
2) Blade count: 6
3) Front angle: -13 degree
4) Coating: TiAlN

1) When Vc increases from 150 to 250, the noise significantly improves;
2) Different Vc values have different iron chip colors, indicating different processing temperatures;
3) The change in Fz can also affect the cutting temperature.
