    摘要： A method for machining round material and in particular tubes by the whirling process, in which the whirling tool is designed as an annular cutting tool having an internal tooth system. The center point of the whirling tool is guided from the start on a path or curve so that a tube wall, for example, is not cut through by a linear feed but by a curve-like feed. This curve is followed via a CNC system. Due to the whirling process, which starts immediately, the length of cut of the tool in the workpiece is given a virtually uniform value just after the start of machining so that the chip volume can be optimized. In this way, the radial and tangential forces on the tool can also be reduced, which leads to optimization of the tool.

    摘要： An apparatus for machining a workpiece such as a crankshaft provides a superior combination of low initial and rebuilding costs, high flexibility in tool changeover and alteration of configuration, yet minimizes floor space and noise level while allowing the combining of several machine operations in a single step. The apparatus also permits the use of optimum cutting speeds, cutting tool feeds, cutting tool composition and cutting tool dimensional tolerances. The apparatus includes a lathe bed to which the crankshaft is mounted and rotated at a variable rate of speed, as well as an arbor disposed parallel to the axis of rotation of the workpiece, rotatable in the same direction at a variable speed. At least one cutter disk is fixedly mounted to the arbor. The disk has a plurality of cutting tools disposed about part but not all of its circumfery, the tools being located at a generally increasing distance from the center of the disk in a stepwise fashion. The circumfery of the disk also includes a second cutout portion between the radially outermost and radially innermost tools. The disk is rotated to bring first the outermost and then the sequentially more inner tools into contact with the spinning workpiece, in order to machine it. The workpiece and disk are each rotated at programmed, varying rates in order to optimally match the tool feed rate and the workpiece surface linear speed for each machining operation, for example, rough cutting, finish cutting, and dimensioning.
