CUTTING PLATE Russian patent published in 1995 - IPC

FIELD: metal cutting. SUBSTANCE: cutting plate has curvilinear cutting edge, made in accordance with pattern curve, formed by smoothly conjugating parts of changeable radiuses and directions of curvature r₁ r₂ ... Figure, formed by cutting edge, is mirror reflected asymmetrical and has the form of two-dimensional enantiomorph. Conjugated to each other cutting plates are inscribed in circumference or symmetrical polygram form. Cutting plate has two or more holes and is made high in the form of small post. The form expands technological capabilities and improves terms of cutting. One cutting plate is used to fulfil different operations during turning operations, including simultaneous treatment of two different surfaces. Pattern curve of cutting edge provides wide range of cutting angles in plan - from 0 to 120 deg and choice of optimal mode to remove clearance of any value in allowed limits. EFFECT: cutting plate is used in metal cutting operations. 4 cl, 8 dwg
