    Abstract: A cutting insert is provided with at least a circular-arc blade cutting edge as a cutting edge in the form of a substantially quarter circular arc, at an intersection between a rake face and a flank face, and an outer cutting edge extending from one end portion of the circular-arc cutting edge. The rake face is formed so as to be convex in a direction of rotation when the cutting insert is mounted on a tool body. On a section perpendicular to the cutting edge, the rake face is inclined so as to become gentler with distance from the circular-arc cutting edge or outer cutting edge. The circular-arc cutting edge is formed to be convex in the direction of rotation. The outer cutting edge is formed so that its edge ridge line is substantially parallel to the axis of the tool body.

    Abstract: The disclosure relates to surface roughening methods in which a cutting tool having a radial cutting blade with first and second cutting edges is fed along a longitudinal axis of an article while rotating the cutting tool about the axis. The first cutting edge forms a first machined pattern of peaks and valleys on a surface of the article, and the second cutting edge removes at least a portion of the peaks to form roughened fracture surfaces in a second machined pattern defining an arrangement of grooves, corresponding to the valleys, separated by lands, corresponding to the roughened fracture surfaces. The cross section of the grooves is substantially asymmetrical, and each groove may further include a notch. The disclosure also provides cutting tools useful in practicing the surface roughening methods. The disclosure further describes cylindrical articles having interior or exterior surfaces roughened using the methods. The methods, cutting tools and articles have applications including fabrication of cylinder blocks for internal combustion engines.

    Abstract: Machining of aluminum workpieces with diamond or diamond-like carbon-surface coated tools may be conducted in an atmosphere containing hydrogen gas at a partial pressure effective for hydrogen to react with carbon atoms at the surface to form C—H bonds that resist adherence of aluminum to the tool surface. Suitably, hydrogen or a hydrogen-containing gas mixture is confined at the interface of tool and workpieces at the machining site. Hydrogen partial pressure may be determined for a tool-workpiece-machining temperature combination by calculation or experiment.

    Abstract: A tool holder assembly that includes a tool holder member adapted to be secured to a machine tool and a cutting insert support/clamp for clamping and supporting a cutting insert. The support/clamp member includes a plurality of serrations that are engageable with complementally formed serrations on the tool holder whereby a tight fitting engagement is achieved using removable fasteners. The support/clamp includes a clamping arm elastically movable towards and away from a support base and a clamping block connected to the connecting arm adapted to receive clamping forces from a threaded clamping bolt. The clamping bolt defines a force applying surface located in a first plane whereas the clamping block defines a force receiving surface located in a second plane, the first and second planes located at a diverging angle with respect to each other. The clamping block includes an edge portion engageable with a step on the tool holder that is spaced from the clamping arm. The diverging planes and the engagement of the clamping block with the stepped portion increases the force applied by the clamping arm to the cutting insert for a given adjustment of the clamping bolt and resists rollover of the insert.
