Abstract: A process for making a diamond-coated tool and the tool made thereby. The process includes a sintering step. In that step, the tool substrate is sintered in an atmosphere and for a time and at a temperature so that superficial, exaggerated grain growth is promoted that imparts a surface roughness which may serve as anchoring sites during a subsequent diamond coating step which is performed by a vapor deposition technique. The diamond-coated tool prepared by the process includes a large grain substrate surface, and an high bond strength between the diamond coating and the substrate surface.

Abstract: A cutting tool has a compressing segment for imparting a compressive force to produce a non-porous surface layer on a workpiece of porous material. The cutting tool also has a cutting segment to machine the non-porous surface layer for a desired surface finish. Furthermore, a method for machining a workpiece using such a cutting tool may be implemented to produce a non-porous surface layer on a workpiece of porous material and then to produce a desired surface finish.

Abstract: A reciprocating assembly for moving an abrasive element over a workpiece. The reciprocating assembly utilizes a piston arrangement operated by pressurized fluid wherein the abrasive element is extended over the workpiece at one rate and is retracted along the workpiece at another rate.

Abstract: A holder for an abrasive element used to abrade the surface of a workpiece. The holder is made of an abrasive pad resiliently mounted upon a holder in a manner providing to the pad multiple degrees of freedom of motion.

Abstract: A cutting insert with improved chip control and metal cutting capabilities and a toolholder with an improved clamping arrangement for use in combination therewith. The insert includes a first notch disposed in the insert body extending from the cutting end to the mounting end thereof. A top wall of the insert body has a forward section with a cutting edge, a middle section with a second notch extending across substantially the entire insert body and a rearward section. In one embodiment, the forward section of the insert body includes a chipbreaker. In another embodiment, the forward portion includes an advanced cutting material which defines a cutting edge. In yet another embodiment of the insert, the insert body top wall forward section defines the cutting edge and the insert body does not include a chipbreaker.

Abstract: Customized instructions for installation of a device having multiple variable components is described, and are generated by an instruction generator program. A device description file lists a desired set of components for the device. Each of the components is broken down into one or more installation tasks, and the tasks are sequenced in a desired order for installation of the device. Text and graphic modules for inclusion in the instructions are varied based on the physical characteristics of the components, and their interconnection. Scaled line drawings are also generated based on information about each component and its placement in the device.

Abstract: An improved metalcutting insert which incorporates a polycrystalline diamond or a polycrystalline cubic boron nitride material therein as a cutting edge material. The insert substrate includes integral chip control features which eliminate the need for the use of separately attached mechanical chipbreakers.

Abstract: A milling cutter is disclosed that comprises a rotatable adapter plate having a central protrusion on one side of the plate. A cutter ring, having recesses for mounting inserts therein, is provided with bayonet slots and a central opening so it can be fitted with and bolted to the adapter plate. The central protrusion is tapered and a conical grind is put on one of the mating surfaces between the adapter and the cutter plate to aid in disassembly after use of the milling cutter.
