A device for producing relative motion with two translational degrees of freedom between a spindle means (95, 195, 295, 395) with a spindle which bears the first part of a first pair of parts formed from a workpiece and a tool, and a retaining element for holding the second part of the first pair of parts, has a first base part to which a first part of a second pair of parts which is formed from the spindle means (95, 195, 295, 395) and the retaining element is attached. The movement device furthermore comprises a second base part, and at least one of the two base parts can be moved in a straight line with respect to the other along a linear guide with a first translational degree of freedom. A support for bearing the second part of the second pair of parts is coupled to the second base part to be able to swivel by means of a swivel joint around a swivel axis which is located at right angles to the linear guide such that the second part of the second pair of parts can be moved by actuating the swivel joint with a second translational degree of freedom on a circular path. The reaction forces and moments which are formed in the machining of the workpiece with the tool are accommodated by the swivel joint which is made stiff; this makes it possible to make the drive means for actuating the swivel joint lightweight. The movement device as claimed in the invention is relatively simple to produce, dynamic and moreover has a high ratio of useful working space to the required construction space.
Device for producing relative motion with two translational degrees of freedom between a spindle means and a retaining element, said spindle means having a spindle which bears a tool and is attached to a second base part, said retaining element for holding a workpiece and is attached to a first base part, at least one of the two base parts is movable in a straight line with respect to the other along a linear guide with a first translational degree of freedom;
