Abstract:
1. In a sheet metal working center having at least one moving carriage arrangement, a method of machining a sheet comprising the steps of: transferring the sheet secured to a mounting member of the at least one moving carriage arrangement in accordance with a predetermined program for machining of the sheet, the sheet being transferred substantially in XY orthogonal coordinates along the main plane of the sheet; machining the sheet by means of machining units, at least two of the machining units performing different machinings of the sheet, said at least two machining units being positioned in the sheet metal working center having separate XY orthogonal coordinates; combining directions X of said separate XY orthogonal coordinates into a common direction X of said sheet metal working center; transferring the at least one moving carriage arrangement and the sheet secured to the mounting member thereof in said common direction X in accordance with the predetermined program between machinings and/or during machinings performed by said at least two machining units; and providing a control algorithm in a control unit in connection with the sheet metal working center for identifying respective origin points of said separate XY orthogonal coordinates of said at least two machining units, said respective origin points being located in the common direction X.
