A process for separating machine a workpiece

The invention relates to a method of separating processing of a plate-shaped or tubular workpiece to be cut workpiece parts, comprising the steps of: (I) determining safety zones for the cutting contours, wherein the safety zone of a cutting contour indicates a range in which occur a collision between the positioned in the cutting height of the cutting head and the associated tilted workpiece part; (II) determining the holding parts for the cutting contours of the workpiece parts, such that the cutting contour of a workpiece part in a one or more holding webs having, holding member, and a one or more early webs having early part is divided or the retaining part is given by the complete cutting contour, wherein at least one holding part is determined for each cutting contour; (III) selecting a single holding part or at least one holding web for each cutting contour, such that there is at least one processing sequence for cutting the cutting contours, in which the early part of a cutting contour is cut in front of the retaining portion of the cutting contour, wherein prior to the cutting of the holding part of the cutting contour one or more spring webs is at least partially located in the safety zone of the cutting contour and / or one or more holding webs is at least partially located in the safety zone of the cutting contour and / or at least one of the holding part corresponding to at least partially located in the safety zone of the cutting contour cutting contour, a or more further cutting contours (A, C, D) are cut; (IV) determining a defined in step (III) processing sequence for cutting the early and holding parts; and (V) Durchfuhren of Schneidprozesses for Werkstuckteile, the early and Halteteile the Schneidkonturen in the step (IV) determined Bearbeitungsreihenfolge be cut. Furthermore, it relates to a device for separating processing, which is suitable adapted to perform the method.
