Abstract

Zum Ausschneiden von Zuschnitten aus unregelmäßigen Werkstücken (W) werden die Umrißform (U) und die Fehlerstellen (F) der auf einer Auflagefläche (2) aufgebreiteten Werkstücke (W) optisch erfaßt und einem Rechner (10) eingegeben, dann wird durch den Rechner (10) für jedes Werkstück (W) auf Grund dieser Daten und der dem Rechner (10) eingespeicherten Daten über die Zuschnitte (Z) ein Schnittmuster (M) erstellt und in Zuordnung zum jeweiligen Werkstück (W) abgespeichert, worauf die Werkstücke (W) mit einer vom Rechner (10) nach einem die zugehörenden Schnittmuster (M) berücksichtigenden Steuerprogramm ansteuerbaren Schneideinrichtung (5) zerschnitten werden.
Um das Ausschneiden bei Optimierung des Nestens zu rationalisieren, werden die Fehlerstellen (F) und vorzugsweise andere werkstückeigene Merkmale der Werkstücke (W) händisch markiert und die Markierungen gemeinsam mit der Umrißform samt einem Werkstückkennzeichen optisch erfaßt, wird das Kennzeichen als Werkstückkennung für die Zuordnung des errechneten Schnittmusters (M) herangezogen und werden zum Schneiden eines Werkstückes (W) wiederum die Umrißform (U) und/oder Markierung samt Kennzeichen des auf die Arbeitsfläche (6) einer Schneideinrichtung (5) aufgelegten Werkstückes (W) und zusätzlich deren Istlage (I) auf der Arbeitsfläche (6) optisch erfaßt und dem Rechner (10) eingegeben, der einerseits die Istlage (I) in einem die Arbeitsfläche (6) repräsentierenden Koordinatensystem (X, Y) festlegt und anderseits aus den gespeicherten Schnittmustern das zugehörende Schnittmuster (M) heraussucht und es in einer auf die ermittelte Koordinatenlage der Umrißform (U) und/oder Markierung abgestimmten Relativlage für das Steuerprogramm zum Ansteuern der Schneideinrichtung (5) bereitstellt. Unabhängig davon lassen sich bei einer Schneideinrichtung (5) mit unterdruckbeaufschlagbarer Arbeitsfläche (6) über den Rechner (10) in Abhängigkeit von der optischen Erfassung der Umrißform (U) des Werkstückes (W) nur die im Auflagebereich des Werkstückes (W) sich befindenden Saugzonen (602) unterdruckbeaufschlagen.
