Method for scanning the surface of a workpiece

A is disposed on a surface of the detector is probe of the surface of the method, the probe is mounted on the surface of related nominal groove; the determined surface of the surface of the normal line at least one approximate, wherein the upper detection device for detecting surface surface, substantially along the surface of the normal line direction readjustment the face detecting device of the surface of the or force. The surface of the normal line is formed by at least part of the mathematical parametrization outline of determining.
