What is the difference between the front angle of the turning tool and the inclination angle of the

1. The selection principle of the rake angle and the inclination angle of the turning tool is different.

The principle of selecting the rake angle of the turning tool: when the strength and hardness of the workpiece material are low and the plasticity is good, a large rake angle should be taken; Otherwise, a smaller rake angle should be taken; Machining of extra-hard materials (such as hardened steel, chilled cast iron, etc.) can even take negative rake angles; When the bending strength and toughness of the tool material are high, a large rake angle can be taken;

When intermittent cutting or fine work, a smaller rake angle should be taken, but if there is a large auxiliary edge inclination angle at this time, a larger rake angle can still be taken to reduce the radial cutting force; When cutting at high speed, the influence of the rake angle on chip deformation and cutting force is small, and a smaller rake angle can be taken; When the rigidity of the process system is poor, a large rake angle should be taken.

The selection principle of the blade inclination angle: the cutting edge inclination angle should be taken as a positive value during finishing, so that the chips flow to the surface to be worked towards, so as not to scratch the machined surface; For intermittent cutting with large impact load, a large negative edge inclination angle should be taken to protect the cutting edge and improve cutting stability.

When processing high-hardness materials, negative inclination angles can be taken to improve the strength of the tool; Finishing tools for micro cutting can have particularly large inclination angles; The inclination direction of the cutting edge of the hole making tool (such as boring cutter and reamer) should be determined according to the nature of the hole.

When machining through holes, the positive edge inclination angle should be taken so that the chips are discharged from the front of the hole to avoid scratching the hole wall; When machining blind holes, a negative edge inclination angle should be taken to make the chips drain backwards.

2. The angle definition of the front angle of the turning tool and the inclination angle of the cutting tool is different.

The inclination angle of the turning tool is: the angle between the cutting edge and the base surface. The rake angle of the turning tool: is the angle between the rake face and the base surface. The inclination angle of the turning tool is the angle between the main cutting edge and the base surface in the cutting plane, and its main function is to control the chip flow direction and determine the strength of the cutter head;

The rake angle of the turning tool is the angle between the front of the turning tool and the base surface, and its main function is to make the cutting edge of the turning tool sharp, reduce the cutting deformation, make the cutting labor-saving, and the chips are easy to discharge.

3. The front angle of the turning tool and the inclination angle of the cutting tool have different functions.

Rake angle effect: the angle between rake face and base surface, and the rake angle is measured in the main section. Enlarge the rake angle, the tool is sharp, the deformation of the cutting layer and the friction resistance of the front chip are small, the cutting force and cutting temperature can be reduced, and the built-up edge can be inhibited or eliminated, but the rake angle is too large and the tool tip is strong.

Tip inclination: The angle between the main cutting edge and the base surface, measured in the main cutting plane. The direction of chip outflow can be controlled; Appropriate cutting angle can make the cutting edge gradually cut in and out of the gongbo, so that the cutting force is uniform and the cutting process is balanced; A negative inclination increases the impact resistance of the cutting edge, but an excessively large negative inclination increases the radial cutting force significantly.

The rake angle is the angle between the cutting edge and the cutting surface, which plays the cutting arrangement.

role. Blade inclination.

is the angle of the back to the cutting edge.

Decide on the knife. Is it virtual or blunt. It is sharp and fast, but easy to fight.

Blunt knife resistance.

It doesn't matter if the lathe tool holder is stable and a little bit empty.

The boring cutter is empty.

The blade shuddered and fell off.

The rake angle is not the same angle as the inclination angle of the cutting edge, which is the angle between the front of the tool and the base surface. The inclination angle is the angle between the main cutting edge and the base surface, which is measured in the main cutting plane. The rake angle is the angle formed between the faces, and the edge inclination angle is the angle formed between the lines and the faces.

These are two different angles, the rake angle is an angle of the knife warp, and the inclination angle is the angle of the blade.

The rake angle of the turning tool is the angle between the base surface and the surface where the tool is in contact with the chip when the chip flows out during cutting; The inclination angle is the angle between the main cutting edge and the base surface in the cutting plane, which affects the direction of chip outflow and the strength of the cutting edge. That is to say, the front angle of the turning tool is generally a positive rake angle, but this positive rake angle has an inclined angle; When the tip position is the lowest on the cutting edge, the inclination angle of the edge is positive, which is represented by 0, and the outflow direction of the chip is the machined surface; When the position of the cutting edge is at the highest point of the cutting edge, the inclination angle of the cutting edge is negative, which is represented by 0, and the direction of the chip flow out is the surface to be machined; When the inclination angle of the blade is 0, the direction of chip outflow is perpendicular to the cutting edge, and it is directly coiled into a coil. When the tool is cut into the workpiece, it is the cutting edge and not the tip that comes into contact with the workpiece first, which protects the tip from impact or less impact.

To put it simply, one is a longitudinal angle and the other is a transverse angle with an angle.

The main function of the inclination angle of the turning tool is to control the direction of chip flow and affect the strength of the cutter head.

When the inclination angle of the edge is negative, the cutting edge is located at the lowest point of the main cutting edge: when cutting, the chips flow to the machined surface of the workpiece, and it is easy to scratch the machined surface, so that the surface roughness value of the machined surface increases: but the strength of the cutting edge is higher, which is suitable for roughing tools.

When the inclination angle of the cutting edge is positive, the tip of the tool is located at the highest point of the main cutting edge: when cutting, the chips flow to the surface to be machined, which is not easy to scratch the machined surface, and can make the machined parts obtain a small surface roughness value: but the tool strength is poor, and the non-cracking Hui can withstand the impact, which cannot be applied to turning the workpiece that is not rounded, but it is suitable for fine turning tools.

When the edge inclination is zero, the main turning edge is parallel to the base surface: when cutting, the chips are discharged in the direction perpendicular to the main cutting edge.

The front angle of the base shirt of the turning tool is the angle between the base surface and the surface of the surface in contact with the chips when the chips flow out during cutting; The inclination angle is the angle between the main cutting edge and the base surface in the cutting plane, which affects the direction of chip outflow and the strength of the cutting edge.

That is to say, the front angle of the turning tool is generally a positive rake angle, but this positive rake angle has an inclined angle; When the tip position is the lowest on the cutting edge, the inclination angle of the edge is positive, which is represented by 0, and the outflow direction of the chip is the machined surface; When the position of the cutting edge is at the highest point of the cutting edge, the inclination angle of the cutting edge is negative, which is represented by 0, and the direction of the chip flow out is the surface to be machined; When the inclination angle of the blade is 0, the direction of chip outflow is perpendicular to the cutting edge, and it is directly coiled into a coil.

When the inclination angle of the blade is 0, when the tool cuts into the workpiece, the first contact between the blade and the workpiece is the cutting edge and not the cutting edge, which protects the cutting edge from impact or less impact.

The inclination angle is the angle between the main cutting edge and the base surface made by the cutting edge measured in the cutting plane.

The inclination angle is the angle between the main cutting edge and the base surface. When the cutting edge coincides with the base surface, the inclination angle of the blade is zero; When the cutting edge is the highest point of the cutting edge, the inclination angle of the cutting edge is positive; When the cutting edge is the lowest point of the cutting edge, the inclination angle is negative.

The purpose of the blade inclination angle is to control the direction in which the chips flow out.

It controls the direction of cutting outflow and affects the strength of the cutter head.

The inclination angle is measured in the cutting plane to the main cutting edge and the cutting edge.

The angle between the base surfaces made. The attached picture hopes to help you
