PURPOSE:To remove misprogramming and to shorten a working time by automatically replacing coordinate axes in accordance with a tool selected in each working surface in a five-surface working machine or the like. CONSTITUTION:The titled device is provided with an NC workingprogram memory 112 for controlling the working of a working machine and an interpolartor 113 coupled with motors M1-M3 for driving respective axes. In addition, an axis selecting circuit 114 for making plural axes correspond to each other by a surface access command accessed from the memory 112 interlocking with the interpolator 113 and a circuit for determining a positive/ negative on the basis of the combination of the surface access command used at the time of surface access and respective axis signals outputted from the circuit 114 are also arranged. Consequently, the coordinate axes can be automatically replaced in accordance with a tool selected in each working surface and misprogramming can be removed. In addition, the working time for programming can be sharply shortened.
