摘要： An improved laser-assisted machining process has special application to difficult-to-machine materials such as the titanium alloys and high temperature superalloys. A layer of material to be removed by a cutting tool is made weaker by drilling a series of holes using a pulse laser beam ahead of the cutting process so that the tool removes the rest of the weaker material with relative ease. There is a decrease of cutting forces, breakage of the chip to a manageable size, and reduced tool wear.

摘要： A cutting insert presents clearance and rake faces constructed and dimensionally interrelated to provide a plurality of adjacent offset, substantially parallel, non-coplanar cutting edges. The offset is in the range of from about 0.010 to 0.100 inch and the planes along the clearance face, which include the cutting edges, form part of a series of steps defined by intersecting planes. Each of the angles between these intersecting planes has a value of at least about 90 degrees.

摘要： A rotary machining system is presented which uses a housing, a combined spindle and cutting disk, a source of high pressure fluid, a hydraulic line, a needle valve, a carbide ball and a carbide socket to machine superalloys and other difficult-to-machine materials and alloys at high speeds. The hydraulic lines and fluid source provide high pressure fluid through an aperture of the carbide socket into the housing to float the spindle. This fluid acts as a hydrostatic thrust bearing as it separates the spindle from the walls of the housing. Since the spindle and cutting disk are a single unit which are not physically attached to a roller bearing mechanism, they may be quickly and easily inserted and removed to minimize the "down time"0 of the system when the cutting disk needs to be replaced or ground to a sharp edge.

摘要： An improved self-sharpening refractory metal cutting tool presenting an overhanging cutting element of width about equal to the depth of the cut to be taken and of maximum thickness equal to tolerable tool flank wear is provided with a plurality of grooves at least on the rake face of the over-hanging cutting portion, or cutting element, to guide the chip leaving the workpiece and to reduce the cutting forces. These chip-grooves are utilized in sequence as the cutting element is consumed lengthwise during the machining operation.

摘要： A method of polishing workpieces in a magnetic float polishing chamber comprising a lower chamber piece and an upper chamber piece which is removably receivable in the lower chamber piece and is connected to a powered spindle for rotating the upper chamber piece in the polishing operation. The method preferably comprises one or more of the steps of (a) geometrically aligning the upper chamber piece with the powered spindle by machining the upper chamber piece in-situ, (b) machining the contact surface of the upper chamber piece in-situ between various polishing runs, and (c) mounting the lower chamber piece in a manner effective for causing the lower piece to automatically self-align coaxially with the upper chamber piece.
