ABSTRACT:
A method is provided for simulating to a workpiece contour by simulating a milling operation, whereby a blank workpiece is modeled by a family of straight lines in three-dimensional space and all straight lines are parallel to the z-axis. A workpiece contour is determined by intersecting the family of straight lines with a virtual milling edge FK according to a predetermined milling path in three-dimensional space, based on the intersecting points of the straight lines of all swept volumes. A surface grid is formed from the obtained set of intersecting points that describes the workpiece contour.
