Position-measuring device

A position-measuring device for measuring a relative position of two relatively movable objects in a direction of feed and in other degrees of freedom, the position-measuring device comprising:

• a carrier body carrying measuring graduations and extending longitudinally in the direction of feed;
• and
• a scanning assembly which is movable relative to the carrier body and includes a plurality of scanning units for scanning the measuring graduations,
• wherein:
• at least three surfaces of the carrier body each carry a first measuring graduation and a second measuring graduation, each of the first measuring graduations and the second measuring graduations having a series of graduation lines, and the graduation lines of the first measuring graduation being inclined with respect to the graduation lines of the second measuring graduation;
• each of the first measuring graduations and each of the second measuring graduations is associated with at least one of the scanning units for scanning the respective measuring graduation at a scanning location such that, for each of the at least three surfaces, at least two of the scanning units are disposed for scanning the respective measuring graduations of the respective one of the surfaces, the at least two of the scanning units being disposed in each case in such a way, and the graduation lines of the two measuring graduations being inclined with respect to one another in each case in such a way, that two normal planes extending respectively in the direction of the respective graduation lines of the measuring graduations through the respective scanning locations of the at least two of the scanning units associated with a respective one of the surfaces have a common axis of intersection, whereby the three resulting axes of intersection extend through a common point.
