Machine tool and process for machining a workpiece

A machine tool for machining a workpiece by means of one or more tools controlled by means of control data, the machine tool comprising:

• at least 5 simultaneously controllable axes,
• a clamping means for clamping a first workpiece, and
• a control means having a support means for supporting one of the one or more tools, and
• a control device suited to control the tool supported in the support means by means of the control data along a tool path to remove material from the workpiece clamped in the clamping means,
• wherein:
• the machine tool is suited to machine a first workpiece to provide the first workpiece with a first gearing, and the first workpiece is a counter piece to a second workpiece having a second gearing such that a first tooth flank of the first gearing forms a mating flank of a second tooth flank of the second gearing,
• the machine tool further comprises a test system suited to determine, after and/or during the machining of the first workpiece on the machine tool, whether a current geometry of the first gearing of the first workpiece differs from a target gearing geometry of the first gearing of the first workpiece,
• the same support means for supporting the one or more tools is also suited to support the second workpiece, and
• the machine tool is suited to control the second workpiece supported in the support means and the first workpiece clamped in the clamping means relative to each other such that the first gearing of the first workpiece and the second gearing of the second workpiece are in engagement and at least one first flank of the first gearing cooperates with at least one first mating flank of the second gearing.
