PURPOSE:To set offset data in a register of an NC device during an exchange of a toll by changing over a working start switch and a working start signal from a line control device by a change-over circuit. CONSTITUTION:After completing the exchange of tool, offset data is formed in an image of a working program in a host computing system 17, and transferred to a line control device 1. The device 1 outputs a signal in an offset to a change-over circuit 19 through a contact interface circuit 6. Then, the offset data is down-loaded in an NC device 7 to complete a search, and then, a search completing signal is outputted to the circuit 19 through the circuit 6. An interlocking condition of the device 7 is recognized, a working start signal is outputted to the circuit 9, and the offset data is set in a prescribed register. The working program is performed by pushing a working start switch by an operator. |
