Abstract: A method and apparatus for forming cleanly defined holes through reinforced metal matrix material includes a drill bit with a shank portion and flutes on said shank portion, the drill bit capable of withstanding a chip load of at least about 0.008 inch/rev/flute, and preferably in the range of from about 0.008 inch/rev/flute to about 0.012 inch/rev/flute, achieved through turning the bit at a speed within the range of about 18 surface feet per minute ("sfpm") to about 20 sfpm, and advancing the bit at an aggressive rate through the metal matrix material at a rate of from about 3 inches per minute to about 6 inches per minute.

Abstract: A machine tool attachment which provides for material handling, positioning, and clamping during machining and also eliminates the need for custom tool fixtures is described. The machine tool attachment mechanically advances material to be machined through a tubular tail stock and into a head stock. Collets located in the tail stock and head stock automatically power clamp the material and a rotary indexer automatically rotates and indexes the material during the machining operation. Once machining is completed, the material between the head stock and tail stock is further clamped by the attachment and then cut by the machine tool. Remaining material can then be advanced by the attachment and the process repeated. The machine tool attachment interfaces with a numerically controlled machining center which transmits signals to control the functions of the attachment for proper coordination with the machine tool.
