PURPOSE:To facilitate maintenance of NC data without increasing an amount of NC data by inputting a machining condition matching with the angle of a corner before machining and performing machining of a corner part through execution of switching to the machining condition during machining of the corner. CONSTITUTION:A process 1-9 wherein the angle of a corner part is calculated is added to the NC data analyzing part of an ordinary NC device. Processing which is changed as a slope to a machining condition matching with the angle of a corner is effected and processing which is returned to an original machining condition from a machining condition for the corner after processing of the corner as a slope thereto is effected are added. This method improves machining precision of a corner without increasing an amount of NC data. Further, the rapid change of a machining condition is prevented from occurring and machining precision is further improved. |
