Based on the analysis of the contradiction between the ultra precision machining demand of hard and brittle materials and the poor machining performance of hard and brittle materials,the research on plastic domain machining of hard and brittle materials is carried out.Firstly,the mechanism of plastic domain machining of hard and brittle materials is analyzed,and the feasibility and guiding theory of plastic domain machining of hard and brittle materials are expounded.Secondly,taking several typical hard and brittle materials as examples,the demand conditions of plastic domain machining under laboratory conditions are discussed.Finally,the feasibility of plastic domain machining of beryllium materials is prospected based on the potential demand of ultra precision machining of beryllium materials.
