    摘要： A method that eliminates or reduces chatter when plunge cutting with boring cutters at different diameters, different tool geometries, different chip loads and different cutting depths, by computing optimal cutting insert locations and relocating such inserts to such optimal cutting locations with different phase angles therebetween; this minimizes the resultant radial force of the combined cutters. The method comprises (a) circumferentially stationing the cutters on the tool at different diameters and depths, but at first phase angle locations; (b) measuring or predicting the maximum radial and tangential cutting forces and chip loads imposed upon each cutter for each revolution of the tool, and repeating such calculation for all revolutions of the tool to acquire force information; (c) computing the different resultant radial forces that result from different phase angle positions for the inserts based on the force information; and (d) selecting the best combination of phase angles that produces a minimal/maximal resultant radial force and relocating the cutters according to such newly selected phase angles for completing plunge cutting.

    摘要： A method of forming deep holes and a gundrill therefore is disclosed. The gundrill has an elongate tubular shank and a cutting tip, each provided with a tubular central region supplying pressurized drilling fluid and a non-circular fluid cross-section defining a drilling fluid return path in conjunction with the hole being formed. The cutting tip flute defines a primary rake surface terminating in an offset point, and a secondary flank surface for forming an outlet with the hole being drilled, sized to maintain fluid pressure in the bottom end space to cool the cutting surfaces and to effectively remove chips as they are formed. A localized relief passage, sized relative to the outlet passage to cause a significant amount of drilling fluid to flow therethrough, is formed behind a peripheral rake edge of the primary rake surface for drilling fluid to exit the end space and cool the tip.

The drilling fluid exiting an orifice of the cutting tip, forms a maximum angle β relative to the hole axis when viewed radially, which is greater than sixty-six degrees in order to minimize drilling fluid stagnation in an elongate fluid return path.

    摘要： An indexable cutting insert of the type having a corner radius and a corner angle adapted for finishing operations comprises a pair of substantially parallel spaced apart faces and at least one peripheral side surface being substantially normal to said faces. A pair of straight cutting edge extend away from the corner at the juncture of the peripheral side surface and a plane positioned closely adjacent and below the juncture of a respective face. To break the chips formed during cutting, a chip breaker recess extents rearwardly and along the cutting edges. The chip breaker recess includes a descending control surface leading to the bottom of the recess followed by an ascending control surface. The descending control surface comprises a first and second planar descending control surface with the first surface being at a shallow angle and the second surface being at a steep angle. The ascending surface directs the chip upwardly toward a central island formed within the plane of a respective face and away from the insert and the cutting edge. The chip breaker recess incorporates an additional shallow chip control recess formed by a raised land extending outwardly toward a corner from the central island along a bisector of a respective corner and a raised bottom surface extending above the bottom of the main chip breaker recess and around the corner. The additional chip control surfaces forming the shallow recess include an ascending corner chip control surface extending upwardly from the raised corner bottom control surface at a relatively steep angle. The recess is configured to change the curling motion of the chip at various depths of cut to enhance the chip breaking forces.

    摘要： In a ceramic indexable cutting insert, an edge strengthening land extends rearwardly of a beveled cutting edge at an angle of from about 80 to about 100 degrees with respect to the peripheral side surface, and a grooved recess extents rearwardly and along the edge strengthening land to direct chips upwardly and outwardly away from the insert and the cutting edge. In one embodiment of the present invention intended for conditions of heavy depth of cut, enhanced edge strength is sacrificed and an edge strengthened land is not provided.

    摘要： A method of designing a cutting tool uses finite element numerical models to predict a response of the tool during a simulated cutting operation on a workpiece, and to simulate a chip-flow phenomenon occurring during the cutting operation. The chip-flow model incorporates representations of a fracture mechanism describing a chip separation phenomenon, a heat-generating mechanism describing a thermal coupling phenomenon, and a shear localization mechanism describing a shearing phenomenon wherein these phenomena occur during the cutting operation. The predicted tool response and the chip-flow simulation are evaluated by an artificial intelligence system to render rule-based judgments which are embodied in recommendations for continuously modifying the models and input design variables until the simulation and response converge to an optimal result.
