CALIBRATING AND OPERATING ROTARY DEVICES, IN PARTICULAR FOR ROTATING PROBE HEADS AND/OR PROBES OF COORDINATE MEASURING DEVICES

摘要

The invention relates to a method for calibrating a measuring arrangement (74, 75) for determining rotational positions of a rotary device (51, 53) that has a first part (51) and a second part (53) which can be rotated relative to the first part (51) about a rotational axis (D), wherein: rotational positions of the first part (51) relative to the second part (53) and/or rotational positions of the second part (53) relative to the first part (51) are detected using a plurality of sensors (74) distributed about the rotational axis (D). A respective measurement signal corresponding to each detected rotational position is generated such that redundant information on the rotational positions of the first part (51) and the second part (53) relative to each other is provided. The redundant information on the rotational position(s) are analyzed such that effects of a translational movement of the first (51) and the second (53) part relative to each other are corrected, the translational movement running transverse to the extension of the rotational axis (D).
