Abstract
A method for controlling the feeding of a band saw blade in a horizontal band saw machine so that the band saw blade is fed at a uniform optimum cutting rate. A control system is provided for controlling the feeding speed and the driving speed of the band saw blade in such a manner that the ratio of the feeding speed to the driving speed is kept constant during a cutting operation and the ratio of cutting resistance to driving speed is maintained constant to provide a constant cutting power.
