Thermal Controlled Cracking Method (TCCM) has developed for more than 60 years with great success. The research progress of TCCM in the past 60 years was reviewed in two directions, i.e. Premade Trajectory Cutting (PTC) and Non-Premade Trajectory Cutting (NPTC) respectively. For PTC, cutting velocity, trajectory deviation and sectional quality are the main process parameters to be optimized. For NPTC, cutting velocity and sectional quality are the main process parameters to be optimized. The crucial technique for optimizing these above parameters is to adopt new techniques for generating advanced heating source, cooling source and better process flow. These new techniques are expected to provide enormous promotion for the developing of TCCM.
