Abstract

Die Erfindung betrifft den Bereich der Werkstückbearbeitung und des Werkstückaufbaus angesiedelt. Sie betrifft insbesondere ein Verfahren zur Festlegung einer Bewegungsbahn (90, 190, 290) eines additiv oder subtraktiv wirkenden Werkzeugs oder eines als Werkzeug verwendeten Laserstrahls. Hierzu wird vorgeschlagen, dass das Verfahren eine Bewegungsbahn (90, 190, 290) festlegt, die in mindestens einem Teilbereich (80, 180, 280) auf der Bearbeitungsebene (22) eine Schraffur aus zueinander parallelen und geradlinigen Bahnabschnitten aufweist, die um einen Schraffurwinkel (A, B, C) gegenüber einer Referenzrichtung (33) geneigt sind. Das erfindungsgemäße Verfahren dient der Festlegung dieser Schraffurwinkel (A, B, C) unter Nutzung einer Radon-Transformation.
