Abstract: 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.

Abstract: 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.

Abstract: A procedure for the numerically controlled processing of a workpiece on a grinding machine having a workholder for the workpiece as well as a wheelhead equipped with a grinding wheel, the wheelhead being pivoted on a wheelslide and able to be shifted together with the wheelslide in relation to the workholder, including detecting positions of a set of points situated within a working range of the grinding machine, covering coordinates of the set of points into basic data for a processing program of the grinding machine, and taking the basic data of the coordinates of the set of points into account while the workpiece is processed.
