The effect of the Angle on cutting machining.
Effect of roughness and tip strength of machined surface. Decrease kappa r ? predominate, reduce the surface roughness value, but also increased the strength of the cutting tool, to improve the cooling conditions. Is too small, can make the vice cutting blade and the machining surface friction increase, cause shock, lower surface quality and tool life. The size of the auxiliary deflection is based on the requirement of roughness and the strength of the tool, not causing the vibration, and trying to get the small value.
The main deflection affects the shape of the cutting layer, the length of the cutting edge and the load on the unit cutting edge. Decrease kappa r predominate, the main cutting edge load per unit length decreases, tool wear is small, improved durability, make machined surface roughness decrease. Smaller main Angle is easy to form long and continuous spiral crumbs, does not favor the chip breaker, so automated processing of chip control strictly, YiQu larger primary Angle. The influence and selection of the auxiliary Angle on processing
The front Angle is big, the blade is sharp, the chip is small, the cutting force is small, the cutting is light. The posterior horn is mainly used to reduce the friction between the posterior surface and the transition surface. The Angle can reduce friction, improve the surface quality and service life, and make the cutting edge sharp. But the rear Angle is too big, the wedge Angle decreases, reduces the strength of cutting edge, reduces the heat dissipation volume, the wear increases, reduces the durability of the tool.
