Abstract: A cutting tool employing negative cutting inserts providing both high volume stock removal and a fine surface finish. The insert utilizes negative radial and positive axial rake angles and incorporates a lead angle of between about 30.degree. degrees to about 90.degree. degrees.

Abstract: A face mill having one or more cartridges for adjustably supporting cutter inserts on the end face of the rotating tool body. Each cartridge has a convex arcuate surface seated against a concave arcuate seat surface formed on or in the milling tool body. A torsion bar is integrally extended from the cartridge parallel to the axis of the concave seat surface. Also, a manual adjustment screw is located perpendicular to the axis of rotation of the cartridge for applying an adjustment force to the cartridge in opposition to the action of the torsion leaf spring. The torsion bar applies a pre-load force to the cartridge. The manual adjustment screw exerts an opposing force that rotates the cartridge to a desired position for proper orientation of the associated cutter insert.

Abstract: An adjustable cartridge to be mounted in a boring bar, the cartridge including an anvil rotatably affixed to said boring bar, said anvil including a pocket into which a lay-down indexable insert is affixed. The anvil is secured in an axially oriented slot which includes an arcuate seating face. Rotation of the anvil within the slot effects radial adjustment of the insert.

Abstract: Precision parallel mechanical float for compliance automation gaging, parts handling, assembly and other operations involving a combination of tolerance misalignment. Parallel plates separated by three precision resiliently preloaded flat end rods provide resilient yield in a parallel plane as well as tilting under predetermined loading together with automatic recentering through restoring spring bias.

Abstract: An adjusting locator to adjust the axial position of a cutting insert in a cutting tool to eliminate cutting run out. The locator is comprised of a body, a flex flange substantially parallel to the body and spaced from the body by an adjusting groove. The flange is connected to the body by a bridge, which is defined between the adjusting groove and a flex groove whereby the flange flexes using the bridge as the fulcrum of the flex.

Abstract: Chip control insert having parallel face central aperture diamond configuration, cutting edges extending above a planar recess, annular and discrete corner island locating surfaces, each with radially outward pointed chip breaking projections extending from the annular locating surface toward the center of each cutting edge and from each of the islands toward its respective acute and obtuse corner. Islands at the acute corners are larger than islands at the obtuse corners.

Abstract: A lockout mechanism for holding a ball valve in a closed condition for prolonged periods, e.g. while machinery that is supplied with pressurized fluid through the valve is being subjected to maintenance operations. The lockout mechanism indirectly provides a safety feature for the workman while he is working on the machinery.

Abstract: A coupling system for selectively locking a tool to a toolholder, in which the locking mechanism carried by the toolholder has a cross-sectionally compact structure and provides release assist when the tool is being removed from the toolholder. The body of the toolholder has an axial drawbar bore in which a drawbar selectively slides. The forward end of the drawbar bore in combination with the forward end of the drawbar form a tool profile cavity which is contoured to seatably receive a tool profile of the tool. The drawbar is hollow and is provided with a pair of apertures. The locking mechanism within the drawbar comprises a pair of locking fingers which are pivotally mounted on a common pivot pin connected with the body. Each locking finger may rotate so as to be retracted within the drawbar or erupt out of the apertures in the drawbar. Rotation of the locking fingers is effected by interaction between the apertures and the locking fingers as the drawbar is axially moved in the drawbar bore.

Abstract: A cutting insert having a particular configuration for cutting tough metals such as encountered in the turning of railway wheels is provided with a specific chip breaker configuration which tends to strengthen the negative rake cutting land.

Abstract: A machining tool to be mounted upon a cutter body, the machining tool including a cartridge for mounting upon the cutter body and an anvil rotatably affixed to the cartridge, the anvil including a pocket into which is affixed a cutting insert for rotation with the anvil.

Abstract: A rotatable tool head for a machine tool includes a tool slide and a mass balancing counter slide which are radially displaceable in opposite directions. The counter slide is mounted in a central recess of the tool slide such that the mass centers of the tool slide and the counter slide move along substantially the same radial line during tool adjustments. In this manner unbalanced masses present in an arrangement where the slides are positioned in axial or radial adjacent relationship, are substantial eliminated.

Abstract: A machine tool that includes a rotary spindle having a radially movable cutter element. An axially movable drawbar within the spindle is used to move the cutter element to its retracted or extended position. A harmonic drive unit is carried on the spindle for imparting rotary movement to a cam element that has a driving connection with the drawbar. The harmonic drive unit can be controlled through a remotely-operated brake that is adapted to be selectively engaged with a reaction member that forms part of the harmonic drive unit.

Abstract: A densified composite comprises an aluminum oxide matrix reinforced with titanium carbide whiskers of a preferred structure which whiskers are produced according to a process by selecting particular reaction conditions.

Abstract: A method for making a compact for a densified cutting insert, an easily machinable material is cut to the desired form, a plastic molding material having specific properties is contacted with the shaped machinable material, hardened to form a mold, and the resulting mold is used to form a compact for a cutting insert having the desired configuration which compact may be subsequently densified.

Abstract: Piston wrist pin boring tool including semi-finish and finish inserts mounted in individual cartridges adjustably secured in cartridge pockets provided in the boring bar. A carbide shank is brazed to a body provided with a cartridge pocket, and a diamond tip for the finishing insert is provided with a closely controlled flat neutral rake cutting edge supplied with coolant from central passages through the bar.

Abstract: Various techniques are disclosed for controlling the operation of a workpiece inspection procedure using a battery operated probe to contact the workpiece and transmit information back to a controller in a machine tool system. In one embodiment, battery power is applied to the probe transmission circuitry in response to a flash of infrared radiation. In another embodiment, the probe is turned on by touching the probe against a reference surface. In both embodiments, a timer is provided to automatically disconnect the batteries after a predetermined time period. In such manner battery life is prolonged.

Abstract: A thread cutter milling tool that includes a cutter body having two sets of cutter teeth. The cutter body is reversibly mountable on a holder so that either set of teeth is presented to the work. Each set of teeth is formed in an edge of the cutter body that is recessed to form a cutter surface and a chip breaker surface. Each chip breaker surface has a dual action for breaking chips and also for locating the cutter body on the holder.
