PURPOSE:To make a visual check quickly and properly as to whether a non- movable code can be executed as intended by displaying the code at an execution position in drawing and checking the locus of motion of an NC program on a CRT display device. CONSTITUTION:In checking an NC program, the locus of motion is drawn and displayed on a CRT display device in the order of a machining start point 13, an optimum feed machining start point 14, a machining completion point 15 and an NC program end point 16. And M-code instructions and comments are displayed at the points of execution in such a way that M80: Machining fluid 'ON' and M84: machining 'ON' are displayed at the machining start point 13, M90: Optimum feed 'ON' at the optimum feed machining start point 14, M85: Machining 'OFF', M81: Machining fluid 'OFF' and M21: Wire cutting at the machining completion point 15 and M00: Program stop at the program end point 16, respectively. Therefore, the watching of a CRT display screen enables the easy check of an error in the non-mobile codes of the NC program.
