Abstract: A process and a cutting machine for working of lying work pieces, particularly plates, glass-sheets, etc. on a machine-tool by means of a cutting fluid-jet (3), particularly of a laser-jet or a high-pressure water-jet on a lattice-like support (9). At least one fixed work piece is cut by the fluid-jet (3), especially water jet exiting from at least one first nozzle (2), so that the work piece (1 a) is preferably separated by a cut gap (7) from a rest piece (1 b). The respective working position of the nozzle (2) relative the work piece (1 a) is controlled. For hindering a tilting of the work piece (1 a) and/or the rest piece (1 b) during the processing of the work piece (1 a), border-fixing and distance-holding elements (8) are associated with the cut gap (7) in such a manner, that the neighboring border-fixing and distance-holding elements (8) are arranged from each other in a distance depending on the outline of the work piece (1 a) and/or of a respective length of the cut gap (7).

Abstract: A cutting device (1) for cutting bone tissue (3), which is particularly intended for correcting malpositions, and which enables a segment of the bone tissue (3) to be cut along a predetermined cut surface (5). The cutting device (1) produces a high pressure fluid jet (2) which is guided by a control program stored in a control unit (4) to produce a cut surface (5) having a desired configuration, for example, a circular arc shape. The resulting bone parts (6, 7), created in this manner, can be fixed in a corrective position (8) with little effort and without significant loss of material. A collector (9), which is equipped with a supply line (14) for supplying a rinsing liquid and with a suction line (13), is provided for collecting the fluid from the fluid jet (2). Collector (9) simultaneously serves to reduce the energy remaining in the high-pressure fluid jet (2).
