Abstract
Abstract An apparatus for measurable displacement of an object in a plurality of coordinates by means of guide systems, which comprises an object carrier which is measurably displaceable. Guiding systems for the object carrier are separated from each other. Measuring systems are coordinated to the guiding systems and defining axes, and the working point is disposed on the object always in the section of the axes.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
144 words
An apparatus for measurable displacement of an object in a plurality of coordinates by means of guide systems, comprising a measurably displaceable object carrier adapted to carry an object thereon, at least two guiding system means separated from each other for respectively guiding said object carrier, the latter operatively connected to said guiding system means, respectively, a measuring system means coupled to each of said guiding system means, respectively, and each defining a measuring axis, respectively, each of said measuring system means for indicating a displacement movement of its corresponding guiding system means and of said object carrier, each of said measUring system means including guiding means for moving said each of said measuring system means exclusively in its measuring axis, whereby each working point on said object always being disposed in the crossing point of said measuring axes of said measuring system means.
Claim 2
Independent Claim
144 words
An apparatus for measurable displacement of an object in a plurality of coordinates by means of guide systems, comprising a measurably displaceable object carrier adapted to carry an object thereon, at least two guiding system means separated from each other for respectively guiding said object carrier, the latter operatively connected to said guiding system means, respectively, a measuring system means coupled to each of said guiding system means, respectively, and each defining a measuring axis, respectively, each of said measuring system means for indicating a displacement movement of its corresponding guiding system means and of said object carrier, each of said measUring system means including guiding means for moving said each of said measuring system means exclusively in its measuring axis, whereby each working point on said object always being disposed in the crossing point of said measuring axes of said measuring system means.
Claim 3
Dependent Claim
30 words
