CHANGEABLE CUTTING TIP Russian patent published in 2004 - IPC

FIELD: working by cutting ductile metals and alloys, namely cutting tools with chip-curling members designed for controlling shape and motion direction of chips.

SUBSTANCE: cutting tip has chip-curling surface arranged along main cutting edge and adjoined to it. Cross sections of chip-curling surface are in the form of circle arcs with curvature changed along cutting edge. In order to enhance chips removal out of cutting zone due to additional curling of chip in plane of cross section of chip, radius values of cross sections of chip curling surface in main intersecting planes of tip are changed according to law inverse to arcsine.

EFFECT: improved design of tip.
