ELID grinding characteristics of SiCp/Al composites

In this study, electrolytic in-process dressing (ELID) grinding experiments were conducted on SiCp/Al composites, and the effects of grinding depth and feed speed of work table on grinding force, surface roughness, and surface morphology were investigated. The experimental results showed that the fluctuation range of grinding force and grinding force ratio Cf under ELID condition were smaller than that of the same grinding parameters under wet grinding condition. Additionally, ELID grinding is effective in providing the uniformly grit protrusion and chip storage space. SiC particles were removed in ductile mode, and the brittle fracture of SiC particles were reduced substantially. The high integrity surface of the SiCp/Al composites could be obtained under ELID condition.
