METHOD AND DEVICE FOR CONFIRMING NUMERICAL CONTROL INFORMATION

PURPOSE:To easily and accurately perform the comparison of a working drawing with a display graphic in the working process based on numerical control information by inputting the graphic data of a working raw material and in a working process from a numerical control information generating device, conforming the contraction ratio and the reference point of them to that of the graphic data of the working drawing inputted separately, superimposing them, and displaying them in terms of animation. CONSTITUTION:The graphic data of the working material is inputted from the numerical control information generating device 101, and is stored after converting to information of displayable format on a display device 307, and the graphic data of an outer frame line, the contraction ration, the reference point, horizontal and vertical reference lines, etc., are inputted, and they are converted to the information of format to display on the display device 307, then, are stored in a RAM 104. Next, the constraction ratio and the reference point of the graphic data of the working raw material are conformed to that of the graphic data. Furthermore, the graphic data in the working process is converted to the information of displayable format on the display device 307 based on the contraction ratio and the reference point, and is synthesized with the graphic data of the working drawing, then, the graphic data in the working process is displayed on the display device 307 in terms of animation. Thereby, the comparison of the working drawing with the display graphic in the working process can be easily performed.
