MACHINE TOOL AND METHOD FOR PRODUCING GEARING

摘要

The invention concerns a machine-tool, in particular a milling machine Including a machine frame; a tool carrier mounted on the machine frame for receiving a tool; a drive device for rotationally driving the tool in the tool carrier about a tool axis; a receiving device (6) mounted on the machine frame (1), for receiving a workpiece (7); a first rotary drive device for generating a first relative angular movement between the tool carrier and the receiving device and a second rotary drive device for generating a second relative angular movement between the tool carrier and the receiving device; a translational drive device for generating a relative translation movement between the tool carrier and the receiving device along three axes; a control device, which is designed in such a way that it enables to control the relative rectilinear movements between the tool carrier and the receiving device and the relative angular movement between the tool carrier and the receiving device substantially at the same time; wherein the tool is designed as a face or face circumference milling cutter and contains blades, which exhibit at least one partial contour of a gearing to be milled in the workpiece; wherein the external diameter of the blades is greater than the distance of two adjoining tooth flanks—tooth gap; The invention is characterised in that the control device is designed, to move the tool in such a way through the region of the gearing to be produced that it is displaced globally along the tooth flank to be machined with equal or substantially equal distance with respect to the tooth gap base and/or with respect to the tooth tip of the gearing to be produced.
