| Summary: | The metal matrix composite has become an important material in aerospace and automotive industry due to their mechanical properties such as light weight, wear resistance and high strength. although metal matrix composite, are produced in net shape, there is some need for secondary operation such as machining. The main problem in MMC machining is high tool wear which result in extra cost. This observation has resulted in an investigation to evaluate the effect of machining parameters and Bismuth as modifier on machinability of Al-20%Mg2Si. The classical experimental design was also applied to develop empirical model, (regression model), to represent the relationship between machining parameters and cutting forces, surface roughness and the Bi modifier. |
