Functions of Cutting Tool Bit
Functions of Cutting Tool Bit
No matter used for what processing, cutting tool bit has 3 main angles.
The respective function of cutting tools angle is as below:
1. Rake -
Decide sharpness and strength of cutting edge.
(1) Its size has big influence on chip removal and breaking performance of cnc tools, surface roughness, and machining difficulty level.
(2) If increase rake:
① Advantages:
Make blade sharper and processing easier, reduce chip deformation, cutting force and power.
② Disadvantages:
Decrease intensity, decline radiation volume of cnc router machine bit, affecting tool lifetime.
2. Relief angle -
Make sure there's no friction between wood router bits and work piece.
It has big effect on durability of cutting tool bit and finished surface quality.
Reasonable size depends on nominal thickness of cut level, also related to work piece materials and manufacturing system.
Usually, the larger nominal thickness, the smaller merocerite is; the greater plasticity, the bigger merocerite is.
While the rigidity is worse, or have higher demand to dimensional accuracy, should be with smaller merocerite.
3. Entrance angle -
Control manufacturing direction, thin chippings effectively, protect the weakest parts of blade.
It should be pointed out that, all degrees are correlative to each other. Select in isolation cannot get reasonable value you want.
We can strengthen edge by integrated optimization; and make a free outflow of machining materials from working area, to reduce chip load and prolong flute cutter life.
