Investigation on Surface Finish and Tool Condition while Turning Al20 Mg_2 Si Metal Matrix Composite

Surface roughness is a key measure that defines machined surface integrity. In this current work, an experimental investigation was conducted to determine the effects of cutting conditions on surface roughness when turning the Al20%Mg􀀃􀀄􀀅 metal matrix composite and Bi-treated Al20%Mg􀀃􀀄􀀅 composite. The results showed that surface roughness value improved with cutting speed increment. In addition, Bi treated workpiece showed better surface finish results compared to base composite Keyword- Surface roughness, Built up edge, Metal Matrix Composite
