Abstract

In a method for simulating the machining of workpieces on lathes utilizing a data processor, the unmachined contour of the workpiece to be machined, the finished contour of the workpiece and the contour of the tool are shown two-dimensionally on the screen. The path of movement of a defined tool reference point according to a machining program is shown. The part of the cutting edge of the tool intended to do the cutting is defined. The area traversed by this part of the cutting edge during each machining feed is outlined and made recognisable by a pattern in such a way that lines and patterns that already exist remain visible.
