Aluminum metal matrix composite (MMC) is a kind of difficult to machine material. In general it is inefficient if conventional methods are used to machine it, with worse surface quality and serious wear of the cutting tool. This paper reports experimental investigations of the effect of machining parameters namely servo voltage (SV), pulse-on time (TON), pulse-off time (TOFF) and wire feed rate (WF) on average cutting speed during wire electrical discharge machining (WEDM) of SiCp/6061 Al metal matrix composite. Response surface methodology (RSM) has been used to plan and analyze the experiments. Voltage, pulse-off time and wire feed rate were found to have significant effect on average cutting speed.

Abstract


Aluminum metal matrix composite (MMC) is a kind of difficult to machine material. In general it is inefficient if conventional methods are used to machine it, with worse surface quality and serious wear of the cutting tool. This paper reports experimental investigations of the effect of machining parameters namely servo voltage (SV), pulse-on time (TON), pulse-off time (TOFF) and wire feed rate (WF) on average cutting speed during wire electrical discharge machining (WEDM) of SiCp/6061 Al metal matrix composite. Response surface methodology (RSM) has been used to plan and analyze the experiments. Voltage, pulse-off time and wire feed rate were found to have significant effect on average cutting speed.
