In order to reduce wheel adhesion and improve the quality of ground surface, the ELID (electrolytic in-process dressing) grinding and cryogenic ELID grinding for grinding TC4 was developed. The various factors affecting the ground surface integrity were studied. The grinding forces were measured, grinding chips and the ground surface were studied under SEM. The grinding temperature was analyzed by using FEM. The results indicated that, by using ELID grinding and cryogenic cooling, the wheel adhesion, the grinding forces and grinding temperature were reduced and the ground surface integrity improved distinctly
