Abstract

PURPOSE:To improve the operability of a spindle program and the processing accuracy of tool boxes by including the control program of the spindle to each control program of two tool boxes and using a switching means to allow any program to control the spindle. CONSTITUTION:When the 1st tool box program A1 and the 2nd tool box program A2 are started respectively and the axis C is controlled by a program included in the program A1, a position signal of the axis C is fed back and inputted to decoders C1, C2. The decoders C1, C2 discriminates by which program the axis C is controlled depending on a feedback signal and the content of the programs A1, A2, pulse distributors D1, D2 output a switching command pulse to apply switching so as to control the axis C by, e.g., the program A2. Since the coordinate of the axis C is fed back, linear interpolation of X1-Z1-axis C or X2-Z2-axis C is applied as required.
