Abstract (en)

[origin: WO2013007285A1] The invention relates to an arrangement for measuring coordinates of a workpiece and/or for machining the workpiece. The arrangement has a first part (1) and a second part (3) that can be moved relative to the first part (1). The relative mobility of the parts (1, 3) is specified in addition to a possible mobility of a probe that is optionally additionally fixed to the arrangement, said mobility of the probe being specified by a deflection of the probe from a neutral position during a mechanical probing of the workpiece for the purpose of measuring the coordinates. A measuring body (K1, K2) is arranged on the first or second (3) part, and at least one sensor (s1...s5) is arranged on the other part, i.e. on the second or first (1) part, said sensor (s1...s5) being designed to generate a measurement signal corresponding to a position of the measuring body (K1, K2) an thus corresponding to the relative position of the first (1) and second (3) part.
