Aiming at the edge chipping phenomenon during engineering ceramics machined by Micro-Detonation of Striking Arc Machining(MDSAM),a technology named circumferential wrapping applying pre-stress with low melting point metal is developed to reduce the edge chipping.The circumferential wrapping process was introduced,and the wrapped workpiece was machined by MDSAM.The temperature field and stress field during the wrapping process of engineering ceramics were simulated by FEM.The mechanism of circumferential wrapping to reduce the edge chipping during engineering ceramics machined by MDSAM was revealed.
