Abstract
The present invention is to enable the locus of a tool or the like to be drawn on a display screen (25) based on an NC command program on an optimum scale and as quickly as possible. A microcomputer (10) obtains a magnification for image drawing and center coordinates of an image drawing space such that maximum and minimum coordinate values entered through a key input means (15) will be put in the display screen (25). Based upon such a magnification and center coordinates, the locus of a tool or the like is drawn on the display screen (25). In parallel with the above drawing process, the microcomputer (10) obtains maximum and minimum coordinate values of the NC command program. When a predetermined command is entered through the key input means (15) after completion of the above drawing process, the microcomputer (10) obtains such a magnification for image drawing and center coordinates of the image drawing space that the maximum and minimum coordinate values of the NC command program obtained in parallel with the above drawing process will be contained in the display screen (25). Based upon the thus obtained magnification and center coordinates, the locus of a tool or the like is …
