The invention relates to a method for machining workpieces with a non-round or inconstant contour on usual commercial programmable turning machines. According to the invention, the application and combination of a programming , consisting of threading cycles and rising and falling values for the diametr al and longitudinal axis or of the gradient, of a pilger step technique and of interlaced machining sequences, have almost unlimited possibilities. Preferr ed applications of the inventive method include the production of special screw threads on screw-in bodies e.g., on plastic hip cups or bone screws, e.g. wi th neutral angles or almost any clamping angles or clearance angles of the thre ad flanks, as well as the production of e.g., inner and outer contours on workpieces for so-called circular wedgings. |
