CUTTING PLATE Russian patent published in 2011 - IPC B23B27/16 

FIELD: technological processes.

SUBSTANCE: cutting plate has a support surface (11), a front surface arranged at the distance from it and at least one rear surface (12) arranged at the positive back angle, which form a circumferential round or polygonal cutting edge, and at least one point (13) of the cutting edge with the maximum distance from the plane, in which the support surface (11) lies, and also at least one point (16, 17) of the cutting edge with the minimum distance from the specified plane. The geometric area of every point of the cutting edge, at least a point (16, 17) of the cutting edge with minimum distance and nearby points is made in the form of a crossing point of a vertical enveloping surface with a plane parallel to the support surface (11), besides, the vertical enveloping surface is arranged perpendicularly to the support surface (11) and is formed by a family of parallel vertical lines (18, 19), which forms an ideal theoretically round or polygonal curvilinear configuration of cutting edges in the plane parallel to the support surface (11) - besides, in this plane there is a point (13) with maximum distance from the plane of the support surface (11).

EFFECT: higher quality of processed surface.
