Claim 0:
1. An alignment device (100) for adjusting a workpiece on a machine table (300) of a numerically controlled machine tool (1000), said device comprising:
a lower plate (20), which defines a center, mountable on said machine table (300) of said machine tool (1000),
an upper plate (10) movably arranged on said lower plate (20), on the upper side of which a workpiece carrier is mountable,
an adjustment mechanism formed between said lower plate (20) and said upper plate (10) and including
a first pair of wedge-shaped elements (70, 80) located on first opposite sides of the center of said lower plate (20) and which, in response to the application of a mechanical force thereto, are displaced with respect to one another, and
a second pair of wedge-shaped elements (70, 90) located on second opposite sides of the center of said lower plate (20) and which, in response to the application of a mechanical force thereto, are displaced with respect to one another,
wherein displacement of the wedge-shaped elements (70, 80, 90) displaces said upper plate (10) with respect to said lower plate (20) and in parallel to a plane of said machine table (300) on which said lower plate (20) is mounted, wherein the upper plate (10) is displaceable in two mutually perpendicular directions with respect to said lower plate (20), and

a locking mechanism for securing the relative position of said upper plate (10) with respect to said lower plate (20).
