MILLING CUTTER TIP Russian patent published in 1999 - IPC

FIELD: machine engineering. SUBSTANCE: milling cutter tip includes upper face, base face and lateral surfaces connecting said faces. Each working cutting edge angle has protrusion embedded relative to adjacent main cutting edge and relative to angular cutting edge. There is trimming edge on frontal upper edge of protrusion, said edge works surface of part to be milled. Due to positive inclination of cutting tip and its negative inclination along radius, horizontal trimming edge may be inclined forwards until contact with part and vertically arranged trimming edge may be inclined backwards as it does not reach part. EFFECT: enhanced axial gap, elimination of undesirable grooves on surface of milled part that may be formed by means of vertically arranged trimming edge. 10 cl, 13 dwg
