INFLUENCE OF CUTTING SCHEME AND METHOD OF FORMATION ON THE DESIGN OF THE EDGE TOOL

Abstract

In the process of cutting two problems are solved - removal of the lowering and forming of the surface of the part with the necessary quality parameters. This requires the definition of the cutting scheme and the method of forming the surface of the part. At this time in the literature there is no definite definition of these concepts. In the work, first of all, attention is paid to this problem. It is also shown that the original tool surface may be a real surface that restricts the calibration part of the tool and which is shaping cutting edges or their parts that come in contact with the surface of the part. And it can be formed by the movements of the cutting edges in space, that is, kinematically. The allowance can be divided into layers by surfaces that cover the surface of the part with the subsequent shredding of each such layer, or surfaces that cross the surface of the part, then dividing them into chips. Methods of shaping a blade tool can also be two. This is either a linear contact, or a point. Schemes of cutting and methods of forming together with the relative movements of the tool and the details and imagination of the design engineer create wide opportunities for the formation of different types and types of cutting tools.
