Factors Affecting the Life of Tungsten Carbide Cutting Tools

Factors that affect the life of tungsten carbide cutting tools includes the following:

Cutting speed Vc: increase the cutting speed Vc, the cutting temperature increased, wear and tear, so that the tool life T is reduced.

Feed back to eat with a knife amount αp: ƒ and αp increases the tool life are reduced, but after ƒ increases, cutting temperature more, so a greater impact on T; αp increases, improved heat dissipation conditions, it is less temperature rise of the cutting, and therefore has little effect on tool life.

Impact of tool geometry parameters: the tool geometry parameters affect tool life are: the front corner, the main angle, angle and nose radius deputy. Reduce the main angle, angle and increased Vice corner radius, can play to improve strength and reduce the cutting tool temperature effects, are conducive to improving tool life.

Workpiece material: the strength of materials processing, higher hardness and toughness, cutting both make cutting temperature, reduced tool life.

Tool material: tool material is an important factor affecting tool life, tool material such as thermal conductivity, higher wear resistance, longer cutting tool life, therefore, the choice of high-performance coated tool and tool material, is to improve the tool life effective way.
