The geometric Angle of the cutter

The most direct and effective way to reduce machining costs is to effectively apply different parts of a turning tool. Therefore, in order to select the most suitable cutting tools, in addition to the selection of suitable cutting materials, it is necessary to understand the characteristics of cutting geometry. However, because of the wide range of cutting geometry involved, the focus is now on the application of the front Angle, the back Angle, which is most commonly used, and the effect of both on the cutting process.

Generally speaking, the front Angle has a great influence on cutting force, chip discharge and tool durability.

 

Front Angle influence

 

1) large front Angle and sharp cutting edge;

 

2) for every 1 degree increase of front Angle, cutting power decreases 1%;

 

3) the forward Angle is too large, and the blade strength drops; If the negative front Angle is too large, the cutting force increases.

 

Big negative front Angle

 

1) cutting hard materials;

 

2) large cutting edge strength is required to adapt to intermittent cutting and processing conditions of cutting surface with black skin.

 

Large front Angle is used

 

1) cutting soft materials;

 

2) free cutting materials;

 

3) when the rigidity of the processed material and machine tool is poor.

 

Benefits of using front - Angle cutting

 

1) the cutting efficiency can be improved as the front Angle can reduce the resistance encountered in cutting.

 

2) reduce the temperature and vibration generated during cutting and improve the cutting accuracy;

 

3) reduce the tool loss and prolong the tool life;

 

4) when choosing the correct tool material and cutting Angle, the front Angle can reduce the tool wear and enhance the reliability of the blade
