PURPOSE:To obtain a device which is capable of foreknowing a tool path by drawing in advance a tool path of the following block, when a tool path of a block being in the course of execution is drawn in parallel to the actual movement of a machine. CONSTITUTION:A titled device is provided with a means for drawing in advance a tool path of the following block, when a tool path of a block being in the course of execution is drawn in parallel to the actual movement of a machine. For instance, an operating information of plural blocks is decoded from an NC working program by a block decoding means DEC and stored in an operating information storing means MEM. Subsequently, a display information required for displaying a tool path of a block being in the course of execution at present is generated by keeping pace with a command to a mechanical system based on the operating information, by a present tool path information generating means CNT1, and also a display information required for displaying a tool path to be displayed in the next time is generated by a following tool path display information generating means CNT2. Also, by a display means DPY, such display information is inputted, and the present tool path and the following tool path are displayed. |
