    摘要： A method for producing conical holes (h) in a workpiece (18) by using a substan-tially cylindrical cutting tool (24) having a cutting head diameter essentially smaller than the top and bottom diameter of the hole to be formed. The method comprises the step of positioning the longitudinal center axis (26) of the cutting tool at an an-gle (a), which is offset from a normal to a flat surface of the workpiece such that the inclination of the longitudinal axis of the cutting tool substantially corresponds to the desired inclination of the wall of the conical hole to be formed, while rotating the cutting tool and moving it in a circular path about a principal axis and feeding the tool axially. For making holes having a curved wall section the angle of inclina-tion of the longitudinal center axis of the cutting tool is varied during the machining operation. The apparatus for making such holes comprises a mechanism configured for adjusting an angle of inclination of the longitudinal axis of the cutting tool rela-tive to the principal axis.

    摘要： A fastener assembly is inserted into a throughhole of a composite laminate (20) to thereby fasten the composite laminate together. The throughhole has a length extending from a first outer surface (38) of the composite laminate (20) to a second outer surface (40) of the composite laminate. The throughhole has a first width at the first outer surface, a second width at the second outer surface, and a third width at a point along the length of the throughhole between the first outer surface and the second outer surface. The third width is less than each of the first width and the second width. The fastener assembly includes a substantially annular fastener device (42) having an axial opening (44) and a peripheral surface substantially conforming to the inner surface (61) of the throughhole. An elongate element is tightly received within the axial opening (44) of the fastener device and biases the peripheral surface of the fastener device against the inner surface (61) of the throughhole such that both the fastener device and the elongate element are substantially entirely disposed between the first outer surface (38) and the second outer surface (40) of the composite laminate (20).

    摘要： An orbital drilling tool unit (10) configured to be detachably mounted to a rotatable spindle of a stationary machine tool. The tool unit (10) comprises an outer eccentric body (14) having an eccentric, longitudinally extending cylindrical hole (16), an inner eccentric body (18) rotatably supported in the eccentric hole (16) of the outer eccentric body (14) and having likewise an eccentric, longitudinally extending cylindrical hole (25), a spindle motor (22) for detachably supporting a cutting tool (24) and rotatably supported in the eccentric hole (25) of the inner eccentric body (18). The machine tool end of the outer eccentric body (14) is configured to be concentrically mounted to a tool holder (12) attached to the machine tool spindle for rotating the outer eccentric body (14). A radial offset adjusting means (26, 30) is configured for rotating the inner eccentric body (18) relative to the outer eccentric body (14) for adjusting the radial offset of the spindle motor center axis relative to the center axis of the machine tool spindle, and a means (38) is provided for transferring power to the spindle motor (22) for rotating the cutting tool (24).
