    摘要: A cutting insert having a chipbreaking configuration for effectively embrittling and breaking thin, foil-like chips produced by drilling or other fine-cutting operations is provided. The cutting insert includes a polygonal insert body having a top surface, a side relief surface, and a cutting edge defined therebetween, and a chipbreaker formed by an elongated groove disposed on the top surface behind the cutting edge in combination with a plurality of recesses disposed over the groove having opposing side edges. The back wall of the groove applies curling forces to the chips, while the opposing side edges of the recesses engage and corrugate the chips thereby embrittling them by work-hardening. The corrugated chips are broken by the curling forces applied by the back and rear walls of the groove and the recesses into small pieces that are easily expelled from the vicinity of the cutting operation.

    摘要: A metal cutting tool assembly (1) having an automatically adjustable chipbreaker (23) is provided that comprises a cutting insert (11) for cutting a relatively rotating workpiece, a holder (3) for holding the insert (11), an insert driver (5) for applying a cutting force between the insert (11) and the workpiece, a chipbreaker (23) having a surface (27) that is effective in breaking chips (55, 56) of different thicknesses when positioned at different distances from the cutting edge (19) of the insert (11), and a mounting mechanism (30) for movably mounting the chipbreaker (23) onto the holder (3). The mounting mechanism (30) includes a spring (50) for automatically adjusting the distance between the chipbreaking surface (27) of the chipbreaker (23) and the cutting edge (19) of the insert (11) in response to the forces applied to the chipbreaker (23) by the metal chips (55, 56) that result from the cutting operation. The mounting mechanism (30) may allow the chipbreaker (23) to either slidably reciprocate on the holder (3) toward and away from the cutting edge (19), or to pivotally move with respect to the cutting edge (19). In both cases, the deflection of the spring (50) is proportional to the thickness of the metal chips (55, 56) engaging the chipbreaking surface (27), which in turn automatically provides the appropriate chipbreaking geometry. The inventive tool assembly allows the same chipbreaker (23) to effectively break chips (55, 56) of widely varying thicknesses which are created when the cutting insert (11) is used to make a variety of different types of cuts in a machining operation.

    摘要: An improved cutting insert with chip control features having an insert body having wall regions, sides and top and bottom walls adapted for mounting in a pocket in a holder. The insert body has cutting edges and a diagonal notch or the like in the top and bottom sides. A land region extends rearwardly from the end wall region toward the respective top or bottom wall and defines a surface region of a predetermined width. An ascending wall or back ramp initiates in a portion of the land and terminates at the respective top or bottom wall. A chipbreaker depression initiates in a forward portion of the land proximate the cutting edge and extends into and bisects the back ramp.

    摘要: A round cutting insert includes a bottom surface, a clearance side surface and a top surface. The top surface includes a chip control feature in the form of a continuous, circumferential depression formed by a substantially planar bottom surface and a pair of upward sloping substantially planar side walls that form an angle with respect to the top surface. The chip control feature may also include a plurality of radially offset bumps located in the depression. The bumps may have the same size and shape, or may have a different size and shape. The top surface also includes an elevated island having one or more indexing marks for easy indexing of the cutting insert.

    摘要: A cutting insert having a generally polygonal insert body having a top face, a bottom face and a plurality of side walls extending therebetween. The juncture of each side wall with the top face defines a peripheral cutting edge. A chip breaking groove is formed in the top face and extends alongside the cutting edges. The chip breaking groove includes a descending wall which inclines downwardly from the cutting edges and a back wall which inclines upwardly from the rearward edge of the outside wall. The back wall includes a nose portion adjacent the cutting corner of the insert. The nose portion includes a tip and a pair of side edges which are disposed at an angle relative to the adjacent cutting edges of the insert body such that the width of the chip groove increases as it extends away from the cutting corner. A pair of shoulders are disposed on opposite sides of the nose portion and are disposed at an angle relative to the cutting edges of the insert body such that the width of the chip groove decreases as it extends from the cutting corner. In a preferred embodiment, the angle of inclination of the back wall relative to the top surface of the insert body increases as the back wall extends away from the cutting corner.
