Abstract: The present invention provides a telematics control system for use in a vehicle for determining whether to transmit vehicle data to off-board the vehicle, the vehicle including a vehicle battery and one or more vehicle sensors. The system includes an input arranged to receive vehicle data from at least one of the one or more on-board vehicle sensors, a processor arranged to determine whether the vehicle battery is operably connected to the system, and an output arranged to transmit a wireless communications message indicative of the received vehicle data to off-board the vehicle. The system further includes a logistics activated mode in which it is operable to transmit communications messages and a logistics quiet mode in which it draws no power from the vehicle battery.

Abstract: A chip control insert is disclosed having positive, concave radiused chip breaker entry surfaces, and a locating surface which is equipped with a planar sealing surface and inclined, convex, radiused chip breaker ramp surfaces which undulate along the length of the insert. The intersection of the back ramp surface and the entry surface defines a chip groove. The locating surface has radial nose projections and radius bulges intermediate the length of the polygon sides of the insert.

Abstract: A two cutting edge, indexable insert with integral pressed-in chip breaker wherein the cutting edges are symmetrically inverted relative to each other to thereby provide indexing therebetween. Each cutting edge is provided with a plurality of noses and gullets. The shape of the noses and gullets is predetermined to provide a predetermined thread contour, such as a buttress thread form. Each pressed in chip breaker is spaced from the adjacent cutting edge by a land and is in the form of a raised island having an incident face contour corresponding to the nose-and-gullet shape of the adjacent cutting edge. Each land is angled such that when the insert is mounted for use with an intended inclination, portions of the land are at neutral rake when engaging a workpiece.

Abstract: A cutting insert for metal cutting includes a body portion of a generally polygonal shape having a cutting end including a front end wall, sides, and top and bottom surfaces. The intersection of the top surface, end wall and sides forming a cutting edge. The top surface includes a cutting land of a generally concave shape about an axis longitudinally extending between the sides and sloping downwardly and inwardly from the cutting edge, a chipgroove area adjoining the cutting land and extending inwardly therefrom and disposed at a lower elevation than the cutting edge, and an upsloping chipbreaker portion adjoining the chipgroove area and the cutting land and leading to a plateau disposed at a higher elevation than the cutting edge and chipgroove area. The chipbreaker portion is configured symmetrically about the axis and includes a forwardly extending fingerlike projection on either side of and continuous with a rearwardly recessed region bisected by the axis.

Abstract: A polygonal indexable cutting insert with improved chip control design having a radiused chip groove and discontinuous chip breaker pads for fine finishing in turning and boring operations.

Abstract: An indexable cutting insert having a polygonal body including top and bottom surfaces connected by a peripheral wall having sides and corners. In a generally diamond shaped embodiment, opposite acutely angled corners and the adjacent sides form cutting edges at their junctures with the top surface, forming noses at the corners. A narrow cutting land extends inward from each cutting edge and slopes downward from the nose along both adjacent sides. A chip groove includes a pair of wedge faces, sloping downwardly from the cutting land to a flat floor and a radius blend juncture aligned with the nose and bisecting the adjacent sides. A pair of chipbreaker faces slope upward from the flat floor and backward from a ridge that connects the chipbreaker faces and is upwardly aligned with the juncture of the cutting faces. Various additional features are also disclosed.

Abstract: A flat disk-like tool insert has a plurality of arcuate cutter tips for machining the side surface of a rotating work piece, and a plurality of linear cutting edges for machining a chamfer on the end of the work piece. An endless land surface is contiguous with the cutter tips and the linear cutting edges so as to deflect metal chips away from the machined surfaces. Each tool tip is aligned with two chip breaker ledges that are arranged in a step configuration, such that chips of varying thickness can be effectively and cleanly broken without interference with the machining process. A third chip breaker ledge is set back from each linear cutting edge for breaking chips generated during a chamfering operation.

Abstract: An indexable cutting insert of the type having a corner radius and a corner angle adapted for finishing operations comprises a pair of substantially parallel spaced apart faces and at least one peripheral side surface being substantially normal to said faces. A pair of straight cutting edge extend away from the corner at the juncture of the peripheral side surface and a plane positioned closely adjacent and below the juncture of a respective face. To break the chips formed during cutting, a chip breaker recess extents rearwardly and along the cutting edges. The chip breaker recess includes a descending control surface leading to the bottom of the recess followed by an ascending control surface. The descending control surface comprises a first and second planar descending control surface with the first surface being at a shallow angle and the second surface being at a steep angle.

Abstract: A polygonal indexable cutting insert for cutting aluminum metal comprises rounded cutting corners with adjacent side surfaces joined at an angle of from about 33 to about 35 degress. Grooved recesses extending along each cutting edge have a particular geometry which includes a shallow descending surface followed by a steeply descending surface leading to the bottom of the grooved recess. An ascending surface directs the chip upwardly toward the top face and away from the insert and the cutting edge.

Abstract: In a thread-cutting insert of the type having a plurality of teeth, each of the respective teeth of the insert includes a pair of scallops which intersect closely adjacent to the forward cutting edge of each tooth to form a ridge which tends to split a chip.
