摘要： A cutting tool (110) for forming a hole by means of orbital drilling is provided. The cutting tool includes a body (112) having a first portion (118), which has a first diameter and a first radial rake angle (124: Fig. 2), and a second portion (120) adjacent the first portion (118), the second portion (120) having a second diameter and a second radial rake angle (126: Fig. 3). The second diameter is different from the first diameter and the second radial rake angle (128) is different from than the first radial rake angle (124). In preferred embodiments the second diameter is larger than the first diameter and the first radial rake angle (124) is positive, whilst the second radial rake angle (128) is negative, such that residual stresses may be imparted to the wall of the orbitally drilled hole. A system (110: Fig. 7) for, and a method (300: Fig. 9) of, orbitally drilling a hole are also provided, wherein the system includes the cutting tool (110).

摘要： A method for designing a cutting edge of a cutting element configured for removing material from a workpiece to leave therein a desired end profile (B22,B24,B26). The method comprises the steps of modeling a desired end profile (B22,B24,B26) of the workpiece, the profile having a longitudinal axis and being defined by a bottom surface (B12), a side surface (B16) and an adjustment surface (B14) extending therebetween; defining a lead profile plane (RP1) and an trail profile plane (RPT) spaced therefrom, each of the planes being oriented perpendicular to the longitudinal axis; determining a profile contour defined by the intersection line between the end profile (B22,B24,B26) and the lead profile plane (RPL). The contour profile includes a bottom contour, an adjoining contour and a side contour defined as the intersection lines between the lead profile plane (RPL) and the bottom surface (B12), the adjustment surface (B14) and the side surface (B16) respectively; designing a rake surface and a relief surface, the intersection line between which defines a cutting edge lying in the adjoining surface (B14) and spanning between the lead profile plane (RPL) and the trail profile plane (RPT). The cutting edge is designed such that in any reference plane (RP; FIG. 6A) oriented perpendicularly to the cutting edge, the intersection between each of the rake surface and the relief surface with the reference plane (RP) defines a respective rake line (RK; FIG. 7) and relief line (RF; FIG. 7), the angle (&thetas;B) between the lines RK,RF) being equal to or smaller than a similar angle (&thetas;B) taken along each of a plurality of similar reference planes (RP) disposed between the reference plane (RPn) and the lead profile plane (RPL)

摘要： Provided is a ball end mill that does not interfere with the defect resistance of a cutting edge of which a rotational track forms a convex hemispherical shape. In the ball end mill, a gash 4 is formed at a front end portion of a main end mill body 1 rotated about an axis O and a cutting edge 5 of which a rotational track around the axis 0 forms a convex hemispherical shape having a center C on the axis O is formed at a peripheral edge portion of a wall surface 4A of the gash 4 facing an end mill rotation direction T. A difference between an included angle, which is formed between a straight line connecting a position which is present on the cutting edge 5 and at which a depth of the gash 4 is maximal in a cross-section orthogonal to the cutting edge 5 with the center C and the axis O, and an included angle, which is formed between a straight line connecting a position which is present on the cutting edge 5 and at which a rake angle of the cutting edge 5 is maximal on a positive angle side in the cross-section orthogonal to the cutting edge 5 with the center C and the axis O, is within ±7°.

摘要： It is the object of the present disclosure to provide an improved end mill that can be easily manufactured, reduces cutting forces on the driving tool, limits chatter at high rotation speeds, has better stability, produces smoother cutting surfaces, and has less natural resonating frequencies while in use to permit operation of the end mill over a wider range of operating conditions. The end mill is equipped with a series of sinusoidal cutting edges with a single long pitch arranged regularly or irregularly along the circumferential cutting surface. In another embodiment, the pitch, the cutting angle of the datum line of the sinusoidal cutting edges and the amplitude of the sinusoidal function can be varied.

摘要： Es wird ein Verfahren zur Behandlung und Bearbeitung von Werkzeugen zur spanabhebenden Bearbeitung von Werkstücken, insbesondere Fräswerkzeuge, beschrieben. Diese Werkzeuge bestehen aus einem hochfesten Stahl, Hartmetall oder Keramik und sind mit mindestens einer Schneidflanke und einer Spannut versehen, welche Schneidflanke auf der Schneidseite mit einer Schneidkante ausgestattet ist. Das Werkzeug wird in einer Beschichtungsanlage mit einer ersten Schicht versehen, welche verschleissfest ist gegen Abrasion. Danach wird an den Schneidkanten jeweils eine Fase angeschliffen. Auf die angeschliffene Fase wird in einer Beschichtungsanlage eine zweite Schicht aufgebracht, die widerstandsfähig ist gegen Kolkverschleiss. Dadurch werden Werkzeuge erhalten, die sich durch eine grosse Abrasionsbeständigkeit und eine gute Verschleissfestigkeit auszeichnen, insbesondere beim Bearbeiten von schwierigen Materialien mit hoher Schnittgeschwindigkeit.

摘要： The invention concerns a machining tool, in particular a face cutter for machining fibre-reinforced materials such as carbon-fibre-reinforced plastics, glass-fibre-reinforced plastics or plastics reinforced with polyester threads. The machining tool comprises a plurality of main flutes (1, 2, 3, 4, 5, 6) which form with a trailing premachining land in each case a cutting wedge with a premachining cutting edge (13, 14, 15, 16, 17, 18), and a plurality of auxiliary flutes (7, 8, 9, 10, 11, 12), which correspond to the plurality of main flutes (1, 2, 3, 4, 5, 6), each trail one of the main flutes (1, 2, 3, 4, 5, 6) in the peripheral sense, each distance in the peripheral sense a postmachining land from the premachining land leading in the peripheral sense, and form with the postmachining land a cutting wedge with a postmachining cutting edge (19, 20, 21, 22, 23, 24). The invention is characterized in that the premachining cutting edges (13, 14, 15, 16, 17, 18) extend alternately with right-hand twist about and untwisted along the tool axis, the postmachining cutting edges (19, 21, 23) trailing the right-hand twisted premachining cutting edges (13, 15, 17) extending untwisted along the tool axis, and the postmachining cutting edges (20, 22, 24) trailing the untwisted premachining cutting edges (14, 16, 18) extending with a right-hand twist about the tool axis.
