Abstract
A process of and an apparatus for the automatic measuring of a workpiece. The workpiece is carried on a coordinate table which is mounted for movement relative to a scanning head in two mutually orthogonal directions. A control device moves the workpiece relative to the scanning head at a constant rate in one direction and at a rate in the other direction so as to maintain a constant pressure of the scanner head on said workpiece. The rates of movement in both directions are periodically compared and when equality is reached reversal occurs wherein control of the constant rate is switched to the scanning head and control from the scanning head is switched to a constant rate. This reversal permits uninterrupted measuring in an automatic mode.
