Abstract
Diamond/Al composites are promising materials for thermal management, but the presence of diamond particles makes them extremely difficult-to-cut. To address this challenge, blasting erosion arc machining (BEAM) is suggested for its high efficiency. The removal mechanism, particularly the influence of diamond particles, was first studied through magnetohydrodynamics and heat transfer simulations. Further analysis revealed how differences in the thermal properties between the reinforcements and the matrix result in distinct solid-liquid-gas phase transitions. The debris morphology and composition were analyzed to further clarify the removal mechanism. Experiments confirmed the high-efficiency machining performance of BEAM in diamond/Al composites.
