The tip of the blade is also referred to as the transitional cutting edge, which is a cutting edge between the main and the side angles. Transition cutting edge effect is to enhance the intensity of blade, reduce the point of cutting thickness, make the finished surface is formed under the small cutting thickness, is conducive to improve the surface finish of workpiece, improve the point of the cooling conditions, reduce wear and tear.
The cutting edge of the tool is the main cutting edge and the cutting edge of the cutting edge, with circular and straight lines. Because the tip of the blade is the closest and the surface has been made, the reasonable tip (size, shape) of the blade has a good light effect on the surface of the workpiece.
The tip of the blade determines the smooth finish of the cutting workpiece, and the tip of the blade has different functions, and it is necessary to grind a small circular arc to the tip of the blade.
