It shows that pulse current is the major factor, and magnetic field assisted technology significantly develops the surface integrity whereas it just slightly contributes to improve MRR, EWR, and aerosol emissions when the intensity of magnetic is in the range of 0.1T–0.2T. Based on Taguchi method, a set of experiments are settled to investigate materials removal rate (MRR), electrode wear rate (EWR), and aerosol emissions under MF-EDM process of 45% and 65% SiC p / Al. Thus, in this paper, magnetic field assisted electrical discharge machining (MF-EDM) of HVF − SiC p / Al is proposed to improve the sustainable machining performance including productivity and aerosol emissions which is most harmful to operators’ health.
It’s a tough problem to process HVF − SiC p / Al with superior machining performance and minor environmental effect. SiC particulate reinforced Al-based metal matrix composites with high volume fractions ( HVF − SiC p / Al) is widely applied in many engineering fields due to combining outstanding properties of both metal and ceramic materials.
