A numerically controlled machine tool and method for controlling an automatic rotational alignment operation of a gear wheel on the machine tool

摘要

The present invention relates to a numerically controlled machine tool 100 with at least 5 - axes to the machining of a on a gripping means of the machine tool 100 200 by means of a workpiece clamped on a work spindle 111 of the machine tool 100 accommodated tool, comprising a numerical machine control means 150, which is adapted to the on the work spindle 111 of the machine tool 100 relative to the tool accommodated on the gripping means 130 of the machine tool clamped workpiece 200 on the basis of numerical control data, and wherein said machine controller 150 is further adapted, an automatic rotational alignment process for determining a rotational offset of a finishing a on the gripping means 130 clamped gear 200, and a method for controlling such automatic rotational alignment process, on the machine tool 100.
