【正文】 as microvariable can be transformed into macrovariable) ,are present ,thus roller operation instability may be led by perturbation. Therefore ,this subject will study the interaction mechanism of multi physical field and the influence on processing system stability and processing material quality started with analysis of micro state of executive body. 3. 6 Multi Technology Integration and Coalescence of Accurate Control The material processing machine ,which operate under the circumstance of extraordinary physical field ,is a plicated large scale system ,and some parameters of the system vary on feasible field boundary 。thereby ,to keep under accurate control and adjustment of multi field circumstance ,multidimension coordination,multienergy,conversion,multilevel, information transfer ,interface multiprocess coupling ,etc. is of much significance. Since a variety of multi interaction exists in control model ,it is necessary to establish integration framework of coordination work according to decoupling of control model ,so as to accurate control based on the multi technology integration and coalescence is realized. 3. 7 Quasi Reality Design and Concurrent Design Based on Knowledge Innovation Systems Digitalization and visualization of material processing technology will promote immediately the quality of design, operation and control . Therefore optimization of material processing technology and material processing machine by means of realization of virtual simulation of processing procedure through quasi reality design and concurrent design is one of our pressing study subjects. 3. 8 Mechanical Behavior of Special Function Materials in the Extraordinary Physical Field Many key elements and parts in material processing machine are often under the circumstance of super strong force field ,temperature field ,electronic magic field and flow field ,and must have the functions of constructing special physical interface. However ,it is difficult for mon single substance material such as metal ,ceramic polymer ,etc. to have both high index of single property and excellent overall quality. Therefore we need to use certain material with new functions for key position,for instance ,multi dimension function gradient material with ultrahigh physical property ,multi dimension function gradient material with intelligence. For these reasons ,it is necessary to study basic law and mechanism of these kind of function material mentioned above ,for instance ,stress (strain) distribution function ,failure mechanism and design criteria of material under the circumstance of extraordinary physical field ,static (dynamic) stiffness and damping ,digitalization design and visualization design of processing system made of gradient function material ,etc. ,so that the general mechanics law of element which is under the circumstance of extraordinary physical field and made of anisotropy multi dimension gradient function material is obtained. Nowadays , material processing science and technology is forging rapidly ahead. A forward looking study aiming at key technology problem of material processing machine will provide theory and technology reserve for manufacturing science and industry of 21st century.
