Characteristics of Electrolysis In-process Dressing Grinding of Al/SiCp Composite Materials

ABSTRACT: A study on grinding of 2124 Al/SiCp (15 % SiCp) metal matrix compo-site material with conventional and ELID grindings uses various current duty ratio. Normal forces and tangential forces are monitored. Surface roughness and Vickers hardness numbers aremeasured.When the results are compared ELID grinding shows less grinding forces due to the breakage of the insulating layer formed on the grinding wheel. A smoother surface can be obtained using a high current duty ratio. Vickers hardness number is reduced when ELID grinding is done with high current duty ratio. The results of this investigation are presented in this article. KEY WORDS: ELID grinding, metal matrix composites, copper bonded wheel, surface roughness, Vickers hardness number
