Provided are a method for machining a plate material by using a linear saw, and a numerical control saw machine apparatus. The numerical control saw machine apparatus includes: two carrying mechanisms, which are connected to two ends of a linear saw respectively; at least one control motor, configured for adjusting a distance between the two carrying mechanisms; and a pair of vibration motors, configured for driving the vibration of the linear saw, wherein, the distance between the two carrying mechanisms is adjusted by the control motor based on a monitored change in a torque of the control motor.
