A system for controlling a bar cutter in a steel bar line comprising a rolling length predicting circuit for calculating, on the basis of a scale loss coefficient, a predicted rolling length of a rolling bar material conveyed to the steel bar line, a flying shear cut instructing circuit responsive to the predicted length for determining a cutting length and for operating a flying shear to cut the rolling bar material in accordance therewith, a rolling length measuring circuit for determining an actual rolling length from the cut bar material, and a scale loss coefficient determining circuit for determining the scale loss coefficient based on the actual rolling length so as to correct the predicted rolling length and thereby reduce a cutting error.
