NUMERICALLY CONTROLLED MACHINE TOOL AND METHOD FOR CONTROLLING AN AUTOMATIC ROTATORY ALIGNING PROCESS OF A GEAR WHEEL ON THE MACHINE TOOL

摘要

The present invention relates to a numerically controlled machine tool (100) comprising at least 5 axes for machining a workpiece (200) clamped on a clamping means of the machine tool (100) by means of a tool mounted on a machining spindle (111) of the machine tool (100), comprising a numerical machine control device (150), which is set up to control the tool mounted on the machining spindle (111) of the machine tool (100) relative to the workpiece (200) clamped on the clamping means (130) of the machine tool on the basis of numerical control data, wherein the machine control device (150) is also set up to control an automatic rotatory aligning process for determining a rotatory zero point shift for a final machining of a gear wheel (200) clamped on the clamping means (130), and a method for controlling such an automatic rotatory aligning process on the machine tool (100).
