Electro Discharge Machining Of Aluminium Alloy (LM6)-5 wt.% SiCp Composites Using Copper Electrodes
نویسندگان
چکیده
Metal matrix composites (MMCs) are now gaining their usage in aerospace, automotive and biomedical industries because of their inherent properties like high strength to weight ratio, low wear rate etc. To machine these types of materials conventional machining methods are unsuitable because of high tool wear and tooling cost. Electro discharge Machining (EDM) is one of the important nontraditional machining processes, which is used for machining of electrically conducting, difficult-to-machine materials and intricate profiles. In the present work LM6-5%SiCp composites, which are fabricated by stir casting route, were machined by EDM process. The influence of the various process parameters, i.e. peak current, flushing pressure and pulse on time on the predominant machining criteria, i.e. the metal removal rate (MRR) was studied. Keywords—Electro discharge Machining, LM6-5%SiCp composites, Material Removal Rate, Stir casting
