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). The border-fixing and distance-holding means (8) are attached to the cut gap (7) or are introduced into the cut gap (7). The material of the border-fixing and distance-holding elements (8) is selected …
