Abstract

A "scanning" work-contact probe is deflectable with respect to a measuring-machine head which is driven by the three-coordinate drive system of the measuring machine. The arrangement is such that the probe continuously tracks (scans) a desired profile of a workpiece and, in doing so, measured probe increments (decrements) of deflection with respect to the head are so mathematically combined with head-position data that, in the further circumstance of holding path-velocity magnitude .vertline.V.sub.des. .vertline. of the measuring machine to a constant value, the orientation of the probe head with respect to the locally contacted slope of the workpiece can also be a constant.
