The invention concerns a method of generating gear teeth, wherein a workpiece which is to receive a toothed profile and a cutting tool are advanced toward each other in a rolling feed motion until each tooth flank of the gear profile has been generated after several passes of the tool, wherein in each pass a cut surface containing at least one flank cut is generated on the workpiece, wherein an auxiliary motion is superimposed on the rolling motion, which has the effect that the flank cuts generated in at least two immediately consecutive passes will be connected to each other. In addition, the invention also concerns a gear-cutting machine with the requisite control features to perform the method.

Method of generating gear teeth, and a gear-cutting machine that is operable according to said method

A gear grinding machine, whose tool spindle () is supported on a first swivel-motion unit () seated on a first linear-motion unit (), has a second linear-motion unit () which is arranged on the first linear-motion unit () and carries a dressing spindle () that is capable of being driven in rotary movement.

The invention relates to a machine tool for machining a work piece having a main spindle unit with a preferably vertical spindle axis, and a machining spindle unit, particularly a hobbing spindle unit that is arranged next to the spindle axis in a direction crosswise to the spindle axis to accommodate a machining tool, with said machining spindle unit being displaceable along a first guiding direction, in particular vertically (Z) by means of a first guide and crosswise, preferably perpendicularly (X) or approximately perpendicularly displaceable to the first guiding direction, particularly the vertical, by means of a second guide, can advance to a work piece clamped in the main spindle unit, and can swivel around a swivel axis (B), preferably perpendicularly to the spindle axis (A) of the machining spindle unit, and with the machining tool having an arbitrary number of helically arranged machining elements, in particular a single- or multi-threaded generating means, adapted to execute generating teeth manufacturing methods.
