The role of the tool angle
Regardless of the type of machining used, the tool has three main angles: the rake angle, the plunging angle, and the relief angle. Its role is as follows: 1 front angle: affect cutting force, cutting edge strength and chip flow characteristics; 2 cutting angle: control the direction of cutting force, effectively reduce the chip, protect the weakest part of the cutting edge; 3 back angle: ensure tool cutting It does not rub against the workpiece.
By comprehensively optimizing the three angles of the tool, the cutting edge can be strengthened, and the workpiece material can freely flow out from the cutting zone, thereby reducing the cutting force and prolonging the tool life.
