The performance of Tool wear
The performance of Tool wear

Abrasive wear: Although the hardness of chips and workpieces is lower than cutting tools, but they contain tiny hard particles with very high hardness, which can make grooves on the surface.
 
Adhesive wear: This phenomenon occurs when the friction surface between tool and workpiece material has the conditions of high temperature, high pressure and fresh surface, and the contact surface reaches the distance between circles in the cutting process.
 
Diffusion wear: When the cutting temperature is too high, the chemical elements of the chip, the workpiece and the tool diffuse in the solid state, which changes the original material composition and structure, and makes the tool vulnerable.
