Abstract
A method of cutting off a workpiece using a band saw blade. Chatter oscillation of the band saw blade is detected, the detected chatter oscillation is input to a pulse generator, and pulses based on the inputted chatter oscillation with a frequency not less than a characteristic frequency of a band saw blade supporting system are input from the pulse generator to the motor for imparting to one of the driving wheel and the driven wheel a forced longitudinal oscillation so that a phase of an oscillation the driving wheel along a rotational direction for the driving wheel is substantially inverted with respect to a phase of an oscillation of the driven wheel along a rotational direction of the driven wheel.
