Abstract:
An improved co-ordinate measuring instrument having a sensing head to measure a work piece; said sensing head being attached to a measuring arm that in turn is moveably guided on a cross slide mounted on a measuring table of the coordinate measuring instrument in a linear direction, the improvement comprising said cross slide being moveably guided on a component mounted movable on two guides, attached parallel to one another on the measuring table said component being mounted at one end on a component foot for movement on said two guides, wherein said component foot comprises an extension arm that is mounted movably with respect to said component by at least one joint and is supported on a first guide of said two guides, and wherein said component foot is rotatably mounted on a second guide of said two guides, such that on altering the distance between said two guides said component is rotated in a plane lying orthogonal to the direction of motion of said component on said two guides, so that alignment of said component changes.
