Patent ID: 7925372

Claim:
A multiaxis machine tool for producing workpieces having a helicoidal generated surface, comprising: a workpiece holder for receiving a workpiece; a tool; at least five activatable mechanical axes for machining the workpiece or for positioning the workpiece and the tool in relation to each other; and a control device for activating the mechanical axes, wherein there is provided at least one virtual axis, which can be parameterized as a guiding axis for other axes and then serves only for the synchronization of these other axes wherein a grinding wheel is provided as the tool and, as mechanical axes, at least one positionable radial infeed axis (χ) is provided for the grinding wheel, a grinding slide (ζ) which can be positioned horizontally and orthogonally in relation to the radial infeed axis is provided for the positioning of the grinding wheel in the direction of displacement of the grinding slide, a positionable rotating axis (β) of a clamping head is provided for the rotation of the workpiece in the workpiece holder, a positionable pivoting axis (τ) is provided for the pivoting of the workpiece and the grinding wheel with respect to each other by means of a rotation of the grinding wheel axis or its parallel projection in a vertical plane (B), and a rotating axis (ω) is provided for the driving of the grinding wheel.
