Abstract：

The hot sawing process was analyzed by the experimental test and finite element method, the influence laws of different process parameters on the sawing performance were studied, and the reasons for the influence laws were explored. Based on the assumption of sawtooth linear motion, the sawing process was analyzed, and the influence laws of different process parameters on single tooth sawing force, sawtooth degree and rake face temperature of sawtooth were obtained. The results show that the single tooth sawing force decreases with the increasing of sawing line speed and preheating temperature and increases with the increasing of sawing depth, the sawing tooth frequency f increases with the increasing of sawing line speed, preheating temperature and single tooth sawing depth, and the sawtooth degree GS decreases with the increasing of sawing line speed and preheating temperature and increases with the increasing of single tooth sawing depth. Furthermore, the peak temperature of rake face for sawtooth decreases with the increasing of single tooth sawing line speed, and the distance of the temperature peak point from the tooth tip decreases. However, the peak temperature of rake face for sawtooth increases with the increasing of single tooth sawing depth and preheating temperature, and the distance of the temperature peak point from the tooth tip increases.
