A CNC control system for controlling the axes on the side of the CNC (20) from a PMC (10) coupled to the CNC (20). Instruction values of the axes and group classification data are sent from the PMC (10) to the CNC (20) which then initiates the pulse distribution after the instructions of the same group are all received. Therefore, movements can be started simultaneously on a plurality of arbitrarily combined axes on the side of the CNC (20).
