<p>A method of drawing a locus of a tool, in which the movement of the tool for 3-dimensional machining can be easily recognized. In accordance with a work-shape data prepared on the basis of an input part program statement as a figure definition statement, for example, a cylindrical work figure (1) is drawn on a display (25a) in a shape of a perspective drawing with a YZ co-ordinate system. In accordance with NC data prepared on the basis of an input part program statement as a movement definition statement, the locus (7) of the tool cutting the peripheral surface of the work is drawn on the display. Simultaneously with this, another locus (8) of the tool obtained by developping the said locus of the tool on the YZ plane is drawn on the same display. An operator can easily recognize the movement of the tool, referring to both the locus (7) of the tool based on the working conditions and the locus (8) of the tool based on the drawing of the working. <IMAGE></p> |
