    Abstract: The present invention entails a collet tool (10) for removing a collet (12) from a circumferential retainer or nose piece (14) and for inserting that collet or another collet into a retainer or nose piece (14). Specifically, the tool includes an elongated sleeve (40) having a collet receiving section (42) formed about one end and a plunger reciprocally mounted within the opposite end of the sleeve. To remove a collet from a retainer (14), the free end of the collet is inserted into the collet receiving section (44) and the sleeve (40) is pressed onto the collet (12) causing the collet (12) to be radially compressed and released from its associated retainer (14). To then eject the collet (12) from the sleeve, the plunger (50) is moved into engagement with the collet (12) and the collet (12) is pushed from the sleeve (40). Then, with the tool being free of any collet (12), another collet may be readied for insertion into a retainer (14) by inserting the rear portion of the collet (12) into the collet receiving section (44).

    Abstract: The present invention relates to a method and apparatus for measuring cutting forces associated with a machine tool (10). A force transducer plate (28) forms a part of a bolted joint within the machine tool structure and is positioned within a direct force path. Raised force shunting pads (38) are formed on both sides of the plate thereby limiting the load transfer area of the plate. At least one three-axis load cell (46) is mounted closely adjacent one force shunting pad and elevated relative to the pad such that an acceptable preload is maintained on the load cell. By strategically placing the load cell closely adjacent the force shunting pad and utilizing the force shunting pads to transfer the majority of loads through the plate, hysteresis is minimized, linearity optimized, and the load cell protected from overload.

    Abstract: A cartride-type milling cutter (1) is provided having a cartridge mounting mechanism (13) that resists the centrifugal load applied to the cartridges at high rotational speeds. The milling cutter includes a generally cylindrical cutter body (3), at least one replaceable tool cartridge (11) having a trailing face (21) and a leading face (19) having a cutting insert (31) for cutting a workpiece, and a mounting mechanism for detachably securing the tool cartridge (11) onto the cutter body (3). The mounting mechanism (13) includes a recess (40) in the cutter body (3) for receiving the cartridge (11) that includes a radially canted wall for providing dovetail-type resistance to radial movement of the cartridge (11) and at least one compressively loaded set screw (50) in the cutter body (3) for compressively engaging the leading face of the cartridge in order to seat and retain it within the recess (40). During the operation of the cutter, the centrifugal load is substantially borne by the combination of the radially canted wall and the set screw (50). The mounting mechanism preferably also includes a screw (64) optionally radially-oriented, that passes through a through bore (62) in the sides of the tool cartridge (11) for providing additional insurance against the loosening or breaking away of the cartridge (11) during high speed operation.

    Abstract: Methods for making, methods for using and articles comprising cermets, preferably cemented carbides and more preferably tungsten carbide, having at least two regions exhibiting at least one property that differs are discussed. Preferably, the cermets further exhibit uniform or controlled wear to impart a self-sharpening character to an article. The multiple-region cermets are particularly useful in wear applications. The cermets are manufactured by juxtaposing and densifying at least two powder blends having different properties (e.g., differential carbide grain size or differential carbide chemistry or differential binder content or differential binder chemistry or any combination of the preceding). Preferably, a first region of the cermet comprises a first ceramic component having a relatively coarse grain size and a prescribed binder content and a second region, juxtaposing or adjoining the first region, comprises a second ceramic component, preferably carbide(s), having a grain size less than the grain size of the first region, a second binder content greater than the binder content of the first region or both. These articles have an extended useful life relative to the useful life of monolithic cermets in such applications as, for example, wear. The multiple region cermets of the present invention may be used with articles comprising tools for materials manipulation or removal including, for example, mining, construction, agricultural, and metal removal applications.

    Abstract: A coupling device for high speed rotation applications comprised of a first member (112) about a longitudinal axis (114) having a collar (120) integrally attached to a solid base (122) and a second member (130) about a longitudinal axis (114) having a sleeve (136) which is receivable within the collar(120). When the first (112) and second (130) members are rotated, the sleeve (136) expands within the collar (120) to minimize or eliminate any clearance that may exist between the sleeve (136) and collar (120). The coupling device may, among other applications, be utilized for machine tools such as milling cutters.

    Abstract: A rotary tapered tool holder (10, 10') includes a body or shank (12) including a front contact portion and a rear contact portion (12d). An adapter sleeve (14, 14') is disposed about a portion of the shank (12). The adapter sleeve includes slits that allow radial expansion and contraction of the adapter sleeve. The adapter sleeve (14, 14') includes an inner surface (14b) formed at a first non-zero taper angle with respect to a longitudinal axis (22) of the shank (12), and an outer surface (14a) formed at a second non-zero taper angle with respect to the longitudinal axis (22) of the shank (12). The second taper angle is different than the first taper angle such that an interference fit between the shank (12) and the inner surface (14b) of the adapter sleeve (14, 14') forces the outer surface (14a) of the adapter sleeve into positive contact with a tapered bore (26) of a spindle (28) of the rotary tapered tool holder.
