    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 a portion that is binder rich and which gradually or smoothly transitions to at least a second region. The multiple-region cermets are particularly useful in compressively loaded application wherein a tensile stress or fatigue limit might otherwise be excessive for monolithic articles. The cermets are manufactured by juxtaposing and densifying at least two powder blends having different properties (e.g., differential carbide grain size, differential carbide chemistry, differential binder content, differential binder chemistry, or any combination of the preceding). Preferably, a first region of the cermet comprises a first ceramic component and a prescribed binder content and a second region, juxtaposing or adjoining the first region, of the cermet comprises a second ceramic component and a second binder content less than the prescribed binder content. The multiple region cermets of the present invention may be used in materials processing technology including, for example, compression technology, extrusion, supercritical processing, chemical processing, materials processing, and ultrahigh pressure.

    Abstract: An excavation cutting tool holder retention system. The cutting tool holder retention system includes a cutting tool holder having a holder engagement surface and a support block having a tool holder bore into which the cutting tool holder is inserted. A pin having a pin engagement surface is movably mounted to the support block such that the pin engagement surface may be moved to engage the holder engagement surface. At least one of the holder and pin engagement surfaces defines an inclined surface such that when the pin engagement surface is moved to engage the holder engagement surface, the shank portion of the cutting tool holder will be drawn into the tool holder bore. In the preferred embodiment, at least one of the shank portion of the cutting tool holder and tool holder bore is tapered such that the shank portion of the cutting tool holder will be drawn and wedged into the tool holder bore of the support block when the pin engagement surface is moved to engage the holder engagement surface.

    Abstract: A rotary tapered tool holder (10) includes a body (12) and an adapter sleeve (14) disposed about a portion of the body. The body (12) and the adapter sleeve (14) have front and rear contact surfaces (12c, 12e) with different taper angles. The front contact surfaces (12c) are optimized for an interference fit and the rear contact surfaces (12e) provide an axial stop and support band when the tool holder (10) is assembled into a clamping receptacle (28). Face contact is achieved between a flange contact surface (12k) of the body (12) and a face contact surface (28a) of the clamping receptacle (28).

    Abstract: A toolholder (50) with a controllable critical angle, such as a lead, trailing, rake or clearance angles, includes a tool spindle (42a) for retaining the toolholder in a tool rest (42) of a machine tool. The machine tool (10) includes at least one linear axis, for example, three mutually perpendicular axes, a rotary axis and a rotation axis. The rotary axis and/or rotation axis is controllable to move to a specified position in synchronization with a movement of one of the linear axes. An adaptor (54) supports a cutting tool (56) that is retained in the adaptor by a clamp (58). The cutting tool (56) defines a critical angle, such as a lead angle, a trailing angle, a rake angle and a flank clearance angle, wherein the critical angle is corrected as a vector of movement of at least one of the linear axis is changed. In addition, the cutting tool (56) can be positioned on opposite side of a centerline of rotation of the workpiece to effectively double the life of the cutting tool. A method of controlling a toolholder (50) is also disclosed.
