Abstract

SiC material removal mechanism and ELID grinding mechanism is analyzed, the character and condition of brittle to ductile transition of SiC single crystal, the critical depth of cut, and surface formation mechanism of ductile mode grinding of SiC single crystal are studied, the experiment results show that ELID grinding can realize ductile grinding ,this will lower the surface damage and improve the machining efficiency.
