Cemented Carbide Tools Cutting Parameters

Cemented carbide tools cutting parameters is the general term of cutting speed, feed rate and cutting depth (depth of cut) in cutting motion cutting process. It said the main motion and the feed physical activity, is used to adjust the machine technology parameters.

1.Cutting speed Vc

Selected point relative to the workpiece instantaneous velocity of the main movement, refers to the cutting edge Vc in m / s or m / min.

Turning cutting speed is calculated as:

V c==

Wherein n - workpiece cemented carbide cutting tools rotational speed, in units of r / min;

d - Upper member selected point rotational diameter carbide cutting tools, the unit is mm.

2.Feed rate ƒ

Feed amount cemented carbide cutting tools in the feed amount of displacement of the direction of movement relative to the workpiece, the available workpiece per revolution (stroke) of the amount of displacement is measured, in units of mm / r.

May also use the feed rate Vf: Vf means the selected point relative to the workpiece cutting edge to feed the instantaneous speed of the movement, in mm / s or m / min feed rate. Turning when the feed motion of speed:
Vf = n f

3.Cutting depth ap (depth of cut)

ap refers to the perpendicular to the feed speed measured in the direction of the largest dimension of the cutting layer, and the unit is mm. Figure known cars cylindrical:
ap=

Dw - where the surface to be machined in diameter;
dm - machined surface diameter.

The synthetic cutting motion with synthetic cutting speed of cemented carbide cutting tools

The main motion and feed motion synthesis the movement known as synthetic cutting motion. Cutting edge selected point relative to the workpiece synthetic cutting instantaneous velocity of the movement known as synthetic cutting speed.
