Abstract
There is provided a machining assembly and cutting insert for machining metal or like workpieces, wherein the cutting insert body has a cutting end. The cutting end comprises at least one cutting edge and at least one cutting lip formed adjacent the at least one cutting edge. The at least one cutting lip includes at least one cutting protrusion and associated chip cutting edge to split the chip formed by the at least one cutting edge, for producing chips during machining which are of a width that is sufficiently reduced to allow proper evacuation or removal.
Claims20
An insert for machining workpieces comprising:
- a body having a cutting end with at least one cutting edge and at least one cutting lip, with the at least one cutting lip including at least one cutting protrusion with at least one chip cutting edge extending from a position adjacent the at least one cutting edge of the insert for cutting chips formed by the at least one cutting edge during machining.
A machining tool assembly comprising:
- a holder having first and second ends and a rotational axis, wherein the second end is adapted to be fixedly attached in a machining machine, and the first end having at least one cutting insert mounted thereon, the cutting insert having a body with a cutting end with at least one cutting edge and associated at least one cutting lip, the at least one cutting lip including at least one cutting protrusion with at least one chip cutting edge extending from a position adjacent the at least one cutting edge of the at least one insert for cutting chips formed by the at least one cutting edge during machining.
A cutting insert comprising:
- at least one cutting edge formed on an outer peripheral surface;
- with at least one cutting lip formed adjacent the at least one cutting edge, and at least one cutting protrusion formed in the at least one cutting lip with at least one chip cutting edge formed in association with the at least one cutting protrusion, wherein the at least one cutting protrusion has a width and a height, and wherein the at least one chip cutting edge extends in an orientation relative to the at least one cutting edge to engage a chip cut by the at least one cutting edge and split the formed chip.
