A damping device for vibration damping of components of a coordinate measuring equipment has a damping component which is frictionally connected to the component to be damped. The characteristic frequency of the damping component deviates from the characteristic frequency of the component to be damped.

Damping device for a coordinate measuring equipment

The electronic system (20) of the probe head of a coordinate measuring machine permits the digital setting of parameters which determine the nature and manner of signal processing, such as trigger levels, the characteristic of frequency filters, and time intervals between several coherent probe signal pulses. Different parameter combinations are stored together in data files which can be called up in accordance with the selected measurement task or in accordance with the probe configuration which has been installed in probe head.

A computer-operated coordinate-measurement machine has two length-measurement systems arranged in parallel for measuring the longitudinal displacement of a probe carried by the portal (3-5) of the machine, and these two length-measurement systems (13, 14) may belong to different precision classes. A computer-associated device (16) forms an absolute position-measurement value (Ym) from length-measurement signals of the more precise measurement system (13) and said device forms a dynamic measurement or instantaneous deviation value (Ys-Ym) from the difference between length-measurement signals of the respective systems (13, 14). The computer of the machine calculates the effective instantaneous position (Ym+.DELTA.y) of the probe (9a, b, c) borne by the portal (3-5), using the instantaneous value of the transverse position of the probe on the portal, in conjunction with the absolute measurement value (Ym) and the dynamic measurement value (Ys-Ym).
