Abstract: An indexable cutting insert includes at least two side edges each defining an indexable edge of the insert and at least two cutting teeth are on each indexable edge. The cutting insert includes locating means on a plane of the upper face and/or a plane of the lower face. When mounted on a material removal tool, the locating means cooperate with receivers on the working face of the material removal tool to constrain degrees of freedom of the cutting insert. Further, the mounted cutting inserts each locate the radial edge of the cutting teeth in the active position on a common circumference of a circle centered on an axis of rotation of the material removal tool. A mounting system per see is also disclosed as well as a method of removing material from a workpiece with the material removal tool.

Abstract: A cutting tool is provided and includes a plurality of cutting inserts located in respective insert pockets. The cutting inserts each include a top cutting plane with at least one cutting edge and a bottom support plane. The top cutting plane includes an engagement portion for mating with a respective engagement portion located in the respective insert pocket. A clamping wedge clamps the cutting insert against the respective insert pocket. A shear resistance created between the engagement portions of the cutting insert and the respective insert pocket during operation of the tool is greater than a centrifugal force created during operation of the cutting tool. In an exemplary embodiment, the engagement portions are shown as a plurality of serrations. The cutting tool is particularly useful in high speed milling operations.

Abstract: An indexable insert has one or more recesses formed in a frontside or backside surface which receives a surface of the head of a locking screw. When mounted, the insert is forced against respective support surfaces of an insert pocket. The locking screw is threaded into a counterbored tap hole to engage the insert and provide side locating forces and clamping forces to secure the indexable insert in the insert pocket. More particularly, the indexable insert has a shaped surface recess that mates to a complimentarily-shaped surface on the head of a locking screw and secures the indexable insert in multiple dimensions to a seating surface. A material removal tool and a method of mounting the indexable insert are also disclosed.

Abstract: Mechanical fine adjust boring head including an adjustment drive train through a worm wheel drive of an eccentric cam orbiting a drive key engaging a slide to effect linear radial adjustment. Anti-friction bearings for the cam and orbital drive connection between the cam and drive key provide for smooth nonbinding adjustment.

Abstract: An adjustable tool holder for cutting tools in boring machines having an internal drawbar includes a housing pivotally connected to a rotary spindle and a forwardly disposed cutting tool. A wedged camming surface is positioned forwardly on the drawbar for contact against an internal drive lever axially disposed for pivotal contact against the housing. Upon actuation of the drawbar the housing is stressed to a canted position causing pivotal adjustment of the cutting tool.
