Silicon rod cutting control method of silicon rod cutting system and silicon rod cutting method

The embodiment of the invention provides a silicon rod cutting control method of a silicon rod cutting system and the silicon rod cutting system. The silicon rod cutting control method comprises the step of taking an edge piece; and the step of taking the edge piece comprises: clamping the edge piece formed by cutting by an edge piece clamping mechanism through a machine head through hole of a cutting machine head mechanism; and taking out the edge piece through the machine head through hole by the edge piece clamping mechanism clamped with the edge piece. According to the embodiment of the invention, due to the fact that the cutting machine head mechanism is provided with the machine head through hole in advance, after cutting is completed, the position of the cutting machine head mechanism is kept immovable; movement is not needed; the edge piece clamping mechanism can clamp the edge piece formed by cutting and take out the edge piece through the machine head through hole; and the steps of taking the edge p
