PURPOSE:To relieve the load of a computer and also to execute simply and quickly the correspondence to partial correction at processing by executing the 2nd processing in an NC machine as a cutting path formed at the 1st processing as an input data. CONSTITUTION:The cut path data formed by a cut path forming section 20 is inputted to the NC machine together with additional information required for processing at first. A boundary curve required to localize a cut curved face is inputted by utilizing a manual data input 50 in this case, the boundary curve is formed by a boundary curve forming processing section 60 and the data is stored in a buffer memory together with a plane code and additional information. A data processing section 70 of the NC machine reads sequentially the cut path data, it is decoded by a decoder, only the cut path data in the effective cut region is extracted and edited and the data in the buffer is revised. Each NC data of the buffer memory is converted into a pulse train corresponding to the cutter moving amount at an interpolation circuit 90 and the pulse drives an NC machine tool 110 via a servo system circuit 100. |
