Ccemented Carbide Cutting Tools Cutting Parameters

Cemented carbide cutting tool components:

Flank

Head - the cutting part of the blade

Tool tip - the main and secondary cutting edge Remit called the tool tip

Arbor - used for clamping

Cemented carbide cutting tool geometry parameters include the rake angle γ, declination and φ φ_1, after angle α, and the main edge bevel λ. It is reasonable or not directly affects the accuracy and surface finish, tool life and productivity of labor, as well as tool - parts - the machine tool system vibration resistance. Therefore, the selection of the most favorable geometry parameters is one of the important issues in the cutting. After the size of the angle, affect the frictional force between the rear workpiece. Friction is larger, the faster the tool wears. Tool flank wear after the angle is zero; friction and cutting temperature rise faster, the damage to the tool and more dramatic. Therefore, from the viewpoint of wear, it should choose the larger rear corner.

To choose feed and cutting speed

Machine power and rigidity and iron filings formed in the process of roughing often constraints. The most economical choice of cutting parameters, which is the maximum metal removal rate obtained is a combination of high feed and low cutting speed. It is subject to a number of factors need to consider. Such as the effective power of the machine is sometimes too low, which need to reduce the cutting speed to get the right power.

In the select finishing process feed, surface quality, tolerances and chip breaking requirements should be taken into account. Surface quality is jointly determined by the feed rate, tool nose radius, workpiece stability, clamping and machine overall condition. The chip breaker is determined by the choice of insert geometries. Finishing operations will affect feeding choice, in terms of the wiper trough is undoubtedly a very wise choice.
