【正文】 4 Design experience Graduation design is we learned in the university of technology and the basic courses, all course all professional class after the. This is we have all of the course of the first indepth prehensive review of the total, is also our into social work in front of a theory with the practice of training. Therefore, it is in our four year university life holds an important position. Personally, I hope I can pass the graduation design for your future will be engaged in the work of a light training, to exercise his analysis problem, problemsolving ability, for the future of our motherland in the four construction lay a good foundation. Turn an eye for four weeks of mechanical manufacturing technology and special jig design will be over, the design of curriculum review around the feeling of life as a process of ascension, and in the curriculum design, we constantly see the teaching material, look at reference see material, meet the problem and not understand we analyzed together or ask the teacher for advice and so on to find a useful to our design of data and material, and then will they bee our design such as raw material, through this design we39。s 1 , line wave and pulse plex exerted in solidifying deforming area , super strength contact stress field of material forming interface ,turbulent flow field of molten metal with very big flakiness ratio ,low frequency magnetic field with random frequency ,microwave field for powder metal heating ,ultrasonic field for large volume solidifying ,etc. [4 ] ,are applied. (2) To have the ability to work in critical state so that high stability and ideal performance of processing machine is ensured under the circumstance of reinforced technological condition and multi field coupling operation. For example ,chatter suppressing capability of fast ultra thin rolling under the condition of boundary lubricating state[5 ] ,the capability of self excited vibration suppressing under the condition of special friction state ,synergism stability and disturbance stability of flexible connecting parallel shaft with multi driving system ,etc. [4 ] ,are ensured. (3) To have the ability to accurately control the material processing in order to obtain low loss ,high efficiency and high quality of material processing. For example , super high accuracy on line monitor of products form ,on – line monitor and on line adjustment of products texture and properties ,precision coordination control of multi procedure , on line monitor of micro orientation of metal plastic deformation ,etc. [4 ] ,are ensured. Some products accuracy index may be enumerated as follows : dimensional accuracy ing to , microstructure uniformity to crystal lattice ,strength error to MPa ,etc. [4 ] In short ,only by new concept material processing machine with extraordinary function being designed and made , can special function material be processed.3　Science Problems and Study Contents of Metal Material Processing MachineUnder the Circumstance of Extraordinary Physical FieldIn view of these facts and background mentioned above ,several new research topics can be advanced as follows.3. 1 Coupling Heat Transfer Mechanism of Multi Phase Interface Temperature Stress FieldA brand new microstructure can be obtained through continuously large deformation and fast solidifying when melting metal is in critical state of liquid solid. At this very moment ,high density heat flow and dynamic heat resistance are present in material processing circumstance . A basic theory problem of designing this kind of machine is to study mechanism of heat transmittance and energy conversion ,and to establish mathematical model .3. 2 Friction Constraint Mechanism of Plastic Flow Interface of Material Processing MachineThe coupling between operation mechanism and workpiece is very plicated because plastic flow is present in processing interface. The interface state , determined by velocity , load thermodynamic process , elasticity of operation mechanism ,plasticity of workpiece ,dynamic behaviour of interface sticking sliding and partial hydrodynamic lubrication ,etc ,affect and form friction constraints mechanism peculiar to material processing machine ,because these constraints present strong non linearity 。 function material1　The Time Background of Material Processing MachineIn the long span of history of human progress ,many tools ,machines and methods were created and a variety of materials with different properties were processed.
