Machining performance of high fraction SiC/Al matrix composites (e.g., 50 vol% SiC/Al) is very limited because of their reinforced SiC particles. In order to study the machinability of high fraction SiC/Al matrix composites with blasting erosion arc machining (BEAM), factorial experiment was employed under the negative electrode machining condition. It was found that when peak current was 500 A, MRR (material removal rate) could be as high as 6,000 mm3/min. Besides, surface integrity under different machining parameters was also investigated. Finally, a 50 vol% SiC/Al composites workpiece was successfully machined with BEAM, which demonstrated that BEAM is capable for the machining of high fraction SiC/Al matrix composites.
