Abstract

PURPOSE: To improve the discharge of a chip and the diffusion of heat of cutting, by starting initial cutting with a point, enlarging the region of cutting by a cutting edge with the rotation and proceeding of a tool and shaping the its cutting tip so that the chip is not compressed but spread outward.
CONSTITUTION: A circular throw-away tip 1 made of very hard alloy is a positive tip comprising a pair of parallel flat reference facets, which are the obverse facet 10 and the reverse facet 11, and a flank 12 which has a major diameter D, a width equal to the thickness T of the tip and an angle θ with regard to the obverse facet 10. The tip 1 is provided with a spherical rake facet 13 extending from the flank 12 to a circumference located on the obverse facet 10 and defined by the line of connection of the obverse facet 10 with a plane extending at the same level as the obverse facet and containing the line of intersection of productions of the flank 12 and the obverse facet 10. According to this constitution, the discharge of the chip and the diffusion of heat of cutting are improved.
