Abstract:
1. An assembly comprised of: a) a cutting insert having a central axis extending therethrough, wherein the insert is intended to machine a workpiece by rotation of the insert about the central axis and wherein the insert is comprised of a body having: b) a rotatable toolholder upon which the cutting insert is mounted, wherein the toolholder is adapted to rotate the insert about the central axis at a predetermined rotational speed and wherein the toolholder is adapted to urge the cutting edge to provide continuous contact against the workpiece during a machining operation; c) wherein the cutting insert is secured to the first end of the toolholder, the second end of the toolliolder is secured to a spindle rotated by a driver, and the toolholder is unsupported between the first end and the second end; and d) projections extending from the bottom surface of the cutting insert, wherein the projections are mateable with recesses within the toolholder to provide a positive coupling between the insert and the toolholder when the cutting insert is urged against the rotatable toolliolder for rotationally securing the cutting insert to the toolholder.
