1、 New Trends and Problems in Material Processing Machine Design Theory Abstract : Based on reviewing the historical background, prospecting for the development trend ,analyzing the complicacy and mechanism and summing up some achievements and experiences in scientific research , several new problems

2、and the possible direction of development in material processing technology and machine are proposed ,such as ,producing new concept materials possessing some specific and extraovdinary properties by means of integrating and coalescing conelative frontier science and technology ;and thereafter a bri

3、ef discussion is given. Keywords: interface; extraordinary physical field; procession machine ; function material 1 The Time Background of Material Processing Machine In the long span of history of human progress ,many tools ,machines and methods were created and a variety of materials with differen

4、t properties were processed. Materials and its processing have become one of pillar and driving force of mankind progress. In pace with multi - polar competition in current world and peoples striving perseveringly for happier life ,material function goes beyond unceasingly mens knowledge and imagina

5、tion ,for example ,cryptic function material ,semiconductor material ,energy material ,vibration - absorptive material , super - strength aluminum alloy accounting for 70 percent of application of aeronautics and space ,metal foil of 45m ,deep drawing plate with anisotropy below 1 percent ,electroni

6、c aluminum foil with micro - orientation up to 95 percent ,heat resisting aluminum alloy with super strong specific strength used in aeronautics ,space and deep sea ,etc. Thus several important development trends with distinct time features in material processing domain are shaped up as follows : (1) Creating material processing machine with extraordinary - 2 - physical field for processing material with special texture structures and functions. For example ,applications
