The difference between the Angle of the blade and the Angle of the blade
Simply put, one is the vertical Angle, one is the Angle in the horizontal direction.
This is two different angles, the front Angle is the Angle of the knife, the blade Angle is the Angle of the blade.
The front Angle is not the same Angle, the front Angle is the Angle between the tool and the base. The blade Angle is the Angle between the main cutting edge and the base surface, measured in the main cutting plane. The anterior Angle is the Angle formed between the surface and the surface, and the Angle of the blade is the Angle formed between the line and the surface.
The front Angle of the vehicle knife is the Angle of the surface of the cutter's contact with the cutting when the base and the cutting are out. The blade Angle is the Angle between the main blade and the base of the cutting plane, which affects the direction of the cutting and the strength of the tip. In other words, the front corner of the car knife is usually a front Angle, but the front corner has a tilted Angle; When the tip of the blade is at the lowest point on the cutting edge, the blade Angle lambda is positive, using lambda > 0, and the chip is in the direction of the processed surface. The tip of the blade is at the highest point of the blade, the tip of the blade is negative and lambda < 0 means that the chip is left in the direction of the processing surface. When the tip of the blade is zero, the chip will flow in the direction perpendicular to the cutting edge and turn directly into a roll. When the blade tip lambda > 0, when the tool cuts through the workpiece, the first contact with the workpiece is the blade instead of the tip, which protects the tip from shock or shock.
