Abstract

PURPOSE: To widen the control coverage of cutting length in a running cutting machine of steel bar mill etc. by, when controlling, lessening the time and angle of acceleration and, when cutting, by permitting flow of a certain specified acceleration current.
CONSTITUTION: The criterion varying continuously from the initial acceleration rate to cutting acceleration rate is given to a speed control device 8 in conformity to a cut command when a cutting acceleration rate setting circuit 26 and initial acceleration rate setting circiut 26A are put into a speed criterion generator device 11, and the cutting edge is controlled so that it conforms to this criterion. At the time of starting, the machine is accelerated at an acceleration rate within the max. torque allowable mechanically and, at the time cutting, the acceleration rate of cutting edge is changed continuously so that it will take values at which the acceleration current corresponds to the torque required by the cutting.
