Patent ID: 8182313

Claim:
Carriage arrangement for a machine tool, said machine tool creating machining forces acting on the carriage arrangement during a machining process, said carriage arrangement comprising: a first carriage ( 1 ) having a horizontal upper surface and movably guided on a base ( 8 ) along a first trajectory in a first plane; a second carriage ( 2 ) movably guided on said first carriage along a second trajectory in a second plane; said second plane being horizontal and parallel to the upper surface of the first carriage and said first plane being tilted relative to said second plane; wherein, as defined in a plane orthogonal to said first and second planes, said second trajectory extends horizontally in the direction of said second plane and said first trajectory extends in the direction of the tilt of said first plane; said first trajectory thereby comprising a horizontal component of motion of said first carriage and a vertical component of motion of said first carriage, said horizontal component of motion of said first carriage being parallel to the horizontal motion of said second carriage along said second trajectory, whereby the horizontal movement of the second carriage is capable of being combined with movement of the first carriage along the first trajectory in a manner enabling the second carriage to be adjusted relative to the base in the horizontal and vertical directions without creating overhanging areas of the second carriage such that the second carriage maintains position over the base to prevent deformation due to said machining forces.
