英文摘要： With advanced manufacturing technology development, ceramics has been widely applied on the aerospace, aircraft, automobile, light industry and chemical industry, etc. However, the ceramics machining technology obviously prevent its application. In this project, a novel ceramics cut method is proposed, which uses the microwave beam to cut the ceramic material based on microwave inducing thermal cracks. Combining into both theoretical and experimental study, the microwave beam focusing technology is deeply studied, which ensures the microwave beam energy concentrating on the machining region; the action mechanics between microwave and ceramic material will be researched, and then the energy transformation and translation laws are analyzed; for the ceramic bulk volume heated, the effects on micro-cracks generating and expending by the temperature of thermal action zone and stress distribution are deeply studied; the effects on the cutting edge quality by the cutting technique method and corresponding parameters are investigated using of microwave beam cutting experiments. Through the investigation on microwave beam cutting technology concerning with the corresponding basic theories and key technologies, the key technology problems will be solved, which provides the theoretical and technology in support of applicat
