Abstract
A process and apparatus for finish grinding splines or teeth on workpieces is disclosed which includes a device to check the cross-sectional shape of the grinding portion of the grinding wheel between grinding steps. When a grinding wheel is withdrawn from the workpiece, the cross-sectional contour of the grinding wheel is checked. The device for dressing or sharpening the grinding wheel is controlled by data generated by the checking of the cross-sectional contour of the grinding wheel so that the desired contour is maintained. After being withdrawn from the workpiece, the grinding wheel contacts a strip of metal foil to leave an impression of its contour. A checking head mounted on the device checks the contour of the impression left in the metal foil. The checking head is connected to a computer unit which, in turn, controls the operation of the sharpening or dressing device.
