Abstract
A band saw having a controller responsive to sensing signals as to operating parameters of the saw to generate a material distribution profile during a first cut of a piece of bar stock is disclosed. During subsequent cuts, the controller for the band saw operates control circuits for blade cutting force, blade feed rate and blade speed to maintain a desired, usually constant, material cutting rate of the bar stock, notwithstanding changes in bar stock cross section and changes in band saw geometry during the cut. A method is disclosed in which operating parameters are sensed, a distribution profile generated, and the profile employed during subsequent cuts to control the operating parameters for optimum cutting efficiency.
