摘要： This invention is a method and apparatus for cutting a workpiece which may have interruptions, with a cutting insert having a cutting edge, where the cutting insert is held in a tool holder and is optionally supported by a shim. Coolant, which may contain liquid nitrogen, is introduced through a passageway to a cooling passage located near the cutting edge. The cooling passage may be located either under, behind, or under and behind the cutting edge. Coolant impacts the wall surfaces of the cooling passage near the cutting edge where it is partly evaporated thereby cooling the cutting insert.

摘要： A method and apparatus for improving the surface finish and/or surface integrity of a workpiece formed or shaped with a tool increase the surface hardness of the workpiece during forming or shaping of the workpiece. A method and apparatus for forming or shaping a workpiece also increase the surface hardness of the workpiece during forming or shaping of the workpiece with a tool, as do a method and apparatus for manufacturing a finished part or product from a workpiece. In some embodiments, an expanding jet of cryogen may be jetted to a surface of a workpiece and a tool from a nozzle, wherein the cryogen is at least partially separated into a condensed phase portion and a vapor portion within a downstream portion of the nozzle.
