<p>PURPOSE:To make automatic working of an object to be worked by giving shape data consisting of basic shape data and name of operation to a computer and calculating automatically offset shape of the surface of each working shape for composite shape. CONSTITUTION:The name of operation 28 and basic shape 26 are inputted to an inputting circuit 15 as input signals. A program that operates output signal from inputted name of operation 28 and basic shape 26 is started, and judging is made whether the right end name of operation 28 is (+) or not. If it is (+), the basic shape 26 is corrected by +r and an intrusion prohibition area 27 of a tool 4 is calculated. On the other hand, in the case where the operation 28 is (-), the basic shape 26 is corrected by -r, and the area 27 is calculated. After completion of the operation, it is judged whether data of the basic shape are remaining or not, and when the data are remaining, above-mentioned processing is repeated. When the data are not remaining, area composition is made when all data of basic shape 26 given by the input signal 19 are corrected by the name of operation 28. Then, the area 27 is set, tool control command operation is made and a signal 20 is outputted to a machine tool 12.</p> |
