Coordinate measuring machine with non-contact position detection device and the calibration method

摘要

Coordinate measuring machine (10) with a sensor (14) for three-dimensional measurement of a workpiece (12), wherein the sensor (14) relative to a sensor head (16) is arranged, and with a three-dimensional non-contact position detection device (22) for detecting a position of a on the sensor head (16) arranged marking element (24) relative to at least one reference object (26), characterized in that the sensor head (16) and the at least one reference object (26), in each case, the coupling means (44, 51) for unambiguous mechanical coupling of the sensor head (16) with the reference object (26), and wherein at least the coupling means (51) on the sensor head (16) are designed in such a way that the sensor head (16) in three different layers can clearly be mechanically to the reference object (26) is arranged to be coupled, wherein the marking element (24) in each position, an other known position relative to the reference object (26) assumes.
