<p>PURPOSE:To facilitate the management of working program and the generation of program by making the program numbers of all working programs executed in an NC machine tool the same against the machine working of the same set. CONSTITUTION:Plural NC machine tools 11-1-11-n which perform machine works of different contents are coupled in series and a work is moved to the next NC machine tool 11-i for machining whenever machining is performed on the work at each NC machine tool 11-(i-1). A controller 13 is provided with program number holding means 131-1-131-n and machining start commanding means 132-1-132-n and a first machining start commanding means 132-1 commands a first NC machine tool 11-1 to start machining simultaneously with the turning on of a start switch 122. The other machining start commanding means command commencement of machining of the other NC machine tools simultaneously with the termination of the machining work of the preceding machine tool.</p> |
