<p>PROBLEM TO BE SOLVED: To facilitate machining of the stock on a machining table and carriage of a residual material by providing a supporting means of the stock, a machining energy feeding means, a residual material sucking means, and an indicating device to indicate the positions in a continuously arranged manner. SOLUTION: When a machining position calculating circuit 7 calculates the machining position of a stock 3 in accordance with the machining program stored in a memory 5, an indication position calculating circuit 12 calculates the shape of the stock 3 and the machining shape based on the machining locus of the stock 3. In addition, the indication position calculating circuit 12 calculates the indication positions of a frog pin 2, a clamp 4, and a suction pad 17 based on the position data of the frog pin 2 stored in a frog pin position memory 14, the position data of the clamp 4 stored in an obstacle position memory 15, and the position data of the suction pad 17 stored in a suction pad position memory 16. A display 13 indicates on a display screen the position of the frog pin 2, the position of the clamp 4 and the position of the suction pad 17 based on the indication positions calculated by the indication position calculating circuit 12.</p> |
