NUMERISCH GESTEUERTES GERAET ZUR ANWENDUNG MIT EINEM WERKZEUG UND EIN WERKZEUG DAS MIT EINEM SOLCHEN GERAET AUSGERUESTET IST.

摘要

A numerical control device stores dimensional details of a workpiece, a chuck, and a tailstock as coordinate data items in a memory, computes the positions and shapes of the workpiece, the chuck, and the tailstock based on the coordinate data items, and displays the workpiece, the chuck, and the tailstock as graphic patterns on a display unit based on the computed results. The computation is simplified by using coordinates of a relative coordinate system as the coordinate data items for graphic display.
