Abstract

PURPOSE:To assist the comprehension for the shape of a workpiece after the completion of work by installing, on a display, a means for graphically representing the workpiece through contour line on the CRT of the display, thus permitting the drawing of the shape of the workpiece during work or before work. CONSTITUTION:As for the X-Y-coordinate on the O-plane for the movement of a lower guide for a wire and the UV-coordinate on the Z4+Z3 plane for the movement of an upper guide, in the actual work by use of an electric discharge machine, when the position instruction of (X, U)=(Xo, Uo) is transmitted from a controller, each coordinate X1-X3, Y1-Y3, on the Z1+Z4 plane on the undersurface of a workpiece, Z4+Z5 plane on the uppersurface of the workpiece, and on the Z2+Z4 plane on the F-instruction plane is obtained. On a CRT, each shape of the Z5 plane on the uppersurface of the workpiece, Z plane on the undersurface of the workpiece, and the Z2 plane on the F-instruction plane is drawn through contour line graphic. Therefore, the N-program can be checked without carrying out working, and also the shape can be comprehended through intuition, and the preparation time before working can be reduced.
