A method for grinding the surface of non-round workpieces. The method includes the steps of clamping a workpiece within a machining unit; machining the workpiece; without unclamping the workpiece, contactlessly measuring the workpiece using an optical measuring device having a conoscopic holography sensor with a characteristic measuring range; and machining and measuring the workpiece in an alternating manner to iteratively approach the desired measurements of a specified form by adjusting the distance between the optical measuring device and the surface of the workpiece depending on there being a deviation of the surface from the specified form so that a respectively measured area of the surface of the workpiece remains within the measuring range of the optical sensor.

Method and device for machining workpieces

An apparatus and method for machining workpieces is provided, in particular, for grinding the surface of non-round workpieces. The workpiece is clamped within a machining unit and the surface of this workpiece is contactlessly measured by means of a measuring device while the workpiece is clamped within the machine.
