<p>A method and apparatus for controlling the cutting of bandsaw machines includes continuous feeding of the bandsaw blade relative to the workpiece by alternating the speed at which the bandsaw blade is fed relative to the workpiece between fast and slow, so that the bandsaw blade is continuously periodically fed relative to the workpiece alternately fast and slow. In a first embodiment, the bandsaw blade is fed into the workpiece and a continuously operating control motor is used to control a flow valve to alternate the speed at which the bandsaw blade is fed into the workpiece. In a second embodiment, the workpiece is fed into the bandsaw blade and a continuously operating control motor is used to control a flow control valve to alternate the speed at which the workpiece is fed into the bandsaw blade. In a third embodiment, the bandsaw blade is fed into the workpiece and a continuously operating servo motor is used to drive a lead screw to alternate the speed at which the bandsaw blade is fed into the workpiece. In a fourth embodiment, the workpiece is fed into the bandsaw blade and a servo motor is continuously used to drive a lead screw to alternate the speed at which the workpiece is fed into the bandsaw blade.</p> |
