Abstract
A multiple-coordinate measurement sensor has an improved, high degree of precision of measurement, even at higher measurement speeds. Three multiple-axis guide systems (7,13,19; 8,14,20; 9,15,21) are arranged in parallel to each other. Length-measuring devices (6) and zero-point and contact-force generators (5) of each system are fastened to the reference base (1), and the devices (5,6) detect the positions of the guides (7,8,9) which are closest to the reference base (1).
