    Abstract: A milling tool includes a body which is rotatable about a first axis. At least one cutting tooth mounted on the body having a cutting edge for cutting about the first axis. A wiper tooth extends from the mill body. The wiper tooth includes at least at a portion having a peripheral surface about the second axis and the peripheral surface intersects a face surface defining a cutting edge that is round about the second axis for cutting about the first axis. In some embodiments, the peripheral surface, the face surface and the cutting edge are formed on an insert that is mounted the mill body.

    Abstract: A face milling tool includes a body which is rotatable about an axis, at least one wiper tooth, and at least two primary cutting teeth mounted on the body having a cutting edge for cutting about the axis. The primary cutting teeth are staggered radially relative to each other by a radial shift so that a chip load variation during operation is less than 0.7 times a mean primary-tooth chip load. A method for determining the primary cutting tooth radial positions on a face milling tool body is provided such that a chip load variation during operation is less than 0.7 times a mean primary-tooth chip load.

    Abstract: The flow of heat energy from the cutting edge rim of a self-propelled round annular rotary cutting element (“insert”) to axial-load and radial-load bearings in a cartridge which rotatably supports the insert on a machine tool body is reduced by defining heat flow paths from the insert rim to cartridge components which engages the bearings to have low thermal conductance relative to heat flow paths from the insert rim to other parts of the cartridge. Control over heat flow path thermal conductance is obtained by selection of materials used between the insert rim and the mentioned cartridge components, by reductions in the cross-sectional areas of the critical heat flow paths, and by combinations of those two techniques. Protection of the bearings from heat enables the insert and the cartridge to be reduced in size. Improved mountings of insert-supportive cartridges to tool bodies are disclosed. The insert and the cartridge preferably are shaped to enable the insert to be positioned on a tool body so that the insert's rake face can have a positive rake orientation relative to a workpiece. Arrangements for controlling cuttings chip formation and for handling cuttings chips also are disclosed.
