Tungsten Carbide Cutting Tool Machining Methods

Details: Category: Tungsten Information; Published on Wednesday, 05 November 2014 18:27

Tungsten carbide cutting tool when used in machining has four main machining methods to achieve shape precision, which are movement track method, rapid prototyping, form copying method and generating method.

I. Movement track method

Also known as tool nose movement track method, it achieves shape precision through the movement track of tool nose. When the tungsten carbide cutting tool moves around the workpiece, the surface geometry required will be obtained according to the movement track of the tool nose.

II. Rapid prototyping

It is a kind of machining method carried out by using formed tungsten carbide cutting tools. The cutting edge of formed cutting tools is the shape of workpieces. This method can simplified the machine tool and cutting movement and thus improve efficiency.

III. Form copying method

When form copying method is adopted, the cutting tool will conduct machining according to copying device. The shape precision achieved by adopting form copying method depends on the precision of the copying device and that of its forming movement.

IV. Generating method (generation method)

In this method, the workpiece and the tungsten carbide cutting tool do generating motion during machining. The surface gained by adopting generating method is enveloping surface formed by the generating motion done by the cutting edge and the workpiece. The cutting edge shape must be the conjugate curve of the surface being processed.
