The installation position of the cemented carbide cutting tools, cutting Synthesis of the direction of movement changes, will cause a change in angle of the tungsten carbide cutting tools. Thus research during the cutting process the tool angle, the relative position of the tungsten carbide cutting tools with the workpiece, the relative movement to create a reference system on the basis of this reference system, said reference system. The tool perspective - that of the work reference system defined angle.

Department of tungsten carbide cutting tools work reference
Cemented carbide cutting tools work reference system can be found in the following figure. It is defined as follows:

Department of Cemented Carbide Cutting Tools Work Reference

(1)Working base surface of a pre selected point through the cutting edge perpendicular to the plane of the cutting rate in the synthesis direction.

(2)The work cutting plane PSE selected points through the cutting edge and the tangent to the cutting edge, and a plane perpendicular to the surface of working base. The plane contains synthetic cutting speed direction.

(3)Work the orthogonal plane POE through the cutting edge to the selected point, while the plane perpendicular to the plane of the operative cutting working base surface.

Tungsten carbide cutting tools working angles

Tungsten carbide cutting tools angles defined and marked angle, it is the former, behind the angles between the work plane reference systems. The tool angles marked symbols is: γoe, ɑoe, Kre, λse, γfe, ɑfe, γpe, ɑpe.

The impact to tool working angles in tungsten carbide cutting tools installation

1．Shank deflection of the main and vice declination

As shown in the following figure, turning counterclockwise with the Quartet turret rotation ? angle, the main angle increases, work vice declination will reduce. For example, fine car adjustable ? = k'r Cutters work the Vice the declination k're on equal 0 °.

2．The impact of the cutting blade mounting level of the front, rear corner

As shown below, turning tool cutting edge selected point A above the center of the workpiece h will cause work before and after the changes in the angle. Caused either because the tungstencarbide cutting tools installation, or caused due to edge inclination, as long as the cutting edges of the selected point is not in the direction of the height of the center of the workpiece.The cutting speed of the point A is not perpendicular to the bottom surface of the shank. The working reference plane pse, pre rotation ε corner angle increases ε working after angle decreases ε. Similarly, the cutting edge is below the center of the workpiece when the selected point A, the H-value and ε angle is negative, will cause the angle decreases in the work before, after working angle increased. Machining the inner surface of, and processing of the outer surface of the opposite.

Feed motion's impact on tool angles

1．Into workpiece rotation axis is not parallel to the direction of motion of the work of tungsten carbide cutting tools the main, vice declination

The following figure shows the situation for flipping the a small pallet truck outside the cone. The tool to the direction of the workpiece axis deflection the μ angle (cone half-angle), which led to the work of the main angle decreases, the work vice declination increase.

Feed Motion's Impact on Tool Angles

2．vertical feed motion of cemented carbide cutting tools work before and after angle.

Cutting synthetic movement in the vertical feed cars cylindrical machined surface is the Archimedes spiral, as shown above. Selected on the point A through the main cutting edge machining surface helix angle is η.

Pf profile pf profiles machined surface tilt η angle after angle decreases η angle, rake angle η angle.

The tungsten carbide cutting tools working angles discussed above are considered separately the influence of a factor, tungsten carbide cutting tools in the actual workpiece may skew or the level of both the installation, another feed movement. At this time should be comprehensive consideration of the impact of the results of the various superimposed.
