Abstract
The invention is directed to a method for manually measuring a workpiece with a manually guided coordinate measuring apparatus. The apparatus includes a carrier for a probe which, in turn, carries a probe ball 12 on a deflectable probe pin 11. The carrier is movably journalled in several spatial directions. The probe ball 12 is brought into contact with the geometric element of the workpiece 30' to be measured and is guided therealong in continuous contact therewith. Signals (.phi., .psi., z) of coordinate measuring devices are generated with the movement of the probe. Signals (u, v, w) of a transducer of the probe are generated with a deflection of the probe pin 11. Control signals (80 to 84) are generated from the first signals and/or the second signals and these control signals characterize the start and the end of the measuring operation on the geometric element and the validity of the coordinate measurement values (X, Y, Z).
