摘要

PURPOSE:To reduce the burdens of a monitoring operation and to improve the efficiency of the set-up operation of an NC machine. CONSTITUTION:Working data and alarm data are transmitted between the plural NC machines 21a-21d operated based on the working data and a management unit 11 for transmitting the working data to the NC machines. Also, the command signals of working data transmission and the alarm data are transmitted by radio data communication between the management unit 11 and a handy terminal 50. Thus, the working data are transmitted from the management unit to the NC machines by instructions from the handy terminal and an alarming operation is performed in the handy terminal corresponding to the alarm data from the NC machines.
