ABSTRACT:
For accurately determining the position of a measuring head 14, a multicoordinate measuring machine has an additional measuring device, which essentially is formed by a scanning head 19 having a measuring probe 20, and inserted in a beam 16. The position of a cross arm 6 in a distance A is determined by means of the measuring probe 20 and is passed on over an amplifier 22 to a computer 25 for control and display purposes. The coordinate measuring machine operates with only one length scale 5. The cross arm 6 is supported at its ends and without play on carriages 11 and 12, which can be moved in the X direction in guiding systems 3 and 4, which are arranged parallel to each other.
