ABSTRACT:
With the method and apparatus for machining workpieces according to FIG. 2, the boundary contours of a workpiece (12) are ascertained with the aid of peripheral points (e2, e3; f2, f3; g2, g3; h2, h3), which are obtained by set theory intersection point observations. To this end, a network of auxiliary lines (e, f, g, h) is placed via an intersection line of the surface of the workpiece with a current layer (machining plane), which are linked with the contour of the intersection line (12) in accordance with so-called Boolean rules.
