A recent numerically controlled flame cutter has brought on improvement of efficiency of both marking and cutting, and has resulted higher accuracy to us. However, an automated or numerically controlled equipment is very expensive in the field of not only hardware but also software, and then increasing its running time, from the point of view of investiment, has to be very required. Noevertheless, it still requires many hand operations, therefore it is considered that its running time is a few and does not function as a labor saving or man-less apparatus. Some points requiring hand operation, for example, are as follows. (i) Steel supply and its accurate setting to NC cutter. (ii) Watch and adjustment of flame. (iii) Cutting of bridges for preventing from heat distortion. (iv) Setting the cutting speed, amount of Kerf-width compensation and pre-heating time. (v) Marking characters. (vi) Input paper tapes for every plate and each cutter because of its individual NC. (vii) Others. The Group Control System from Steel out up to Cutting can eliminate those factors against labor-saving or man-less operation with various new automated appratuses and planning out new control methods. In this system one mini-computer with magnetic drums, a magnetic tape and a CRT controls directly 4 NC cutters (2 plasma and 2 gas cutters), steel supply facilities that are 36 line conveyors, a traverser, a graphic pannel for monitoring traverser and conveyors, etc. and other apparatuses. Also this system makes various administrative control, e.g. scheduling for cutting, summing running results of NC cutter, etc. This system, , in other word, is considered as the first attempt in the world of the whole process control system from steel out up to cutting.
