CUTTING PLATE AND ASSEMBLY CUTTING TOOL, INCLUDING SUCH PLATE Russian patent published in 2024 - IPC B23B27/16 

FIELD: cutting tools.

SUBSTANCE: group of inventions relates to a cutting plate used for turning a machined part, and to an assembled cutting tool including such an insert. In compliance with one version, the cutting insert is capable of lengthwise turning and back turning at high feed rate: upper surface; lower surface opposite to upper surface in vertical direction; side portion configured to connect the upper surface to the lower surface; a mounting hole passing through the upper surface and the lower surface; and a plurality of cutting edges formed on the edges, where the upper surface meets the side portion, wherein the upper surface has one or more cutting corners, the plurality of cutting edges includes a major cutting edge and a minor cutting edge extending from the cutting angle, and the incline of the secondary cutting edge used for back turning with high feed is greater than the inclination of the main cutting edge used for longitudinal turning, relative to an imaginary reference plane perpendicular to the vertical direction.

EFFECT: enabling the possibility of longitudinal and reverse turning, unobstructed formation and removal of chips by means of efficient configuration of the shape of the chip shaper.
