At this very moment ,high density heat flow and dynamic heat resistance are present in material processing circumstance[6 ,7 ] . 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 。制備機械。例如：神秘原料功能，半導體材料，原料能量有吸力的材料，在航空領域中占有70%份額的強力鋁合金4~5um的薄金屬片，用各向異性深沖壓金屬板在1%以下；電子鋁箔與強耐熱鋁合金已經(jīng)被應用到航空、宇宙及深海領域中，等等；在原料加工加工領域中不同的時間段里，材料重要發(fā)展趨勢就這樣形成了：（1）在特殊的物理領域里制造原料加工機械，是為了能有特殊的質(zhì)地結構和輔助性的加工功能。（3）原料加工處理正在向高速、重載和高精度在線控制方向上邁進。例如：在高溫環(huán)境下能使那些高溫波或者脈沖以超過104~106K/s的速度冷卻下來；將外表面的凝固、變形合成一體，然后在將超強接觸面應力重新組合成新的分界面；融化的大金屬薄片的湍流；隨機的低頻率磁場用于金屬末加熱的微波、用于大量凝固的超聲波等等都已經(jīng)被應用了。例如：精確的在線監(jiān)測產(chǎn)品成型；在線監(jiān)測和在線調(diào)整產(chǎn)品品質(zhì)和器具還有在線控制金屬、塑膠成型的程序。3．在特殊的物理領域和環(huán)境下金屬材料加工設備的問題和需要學習的內(nèi)容由于這些原因和以上提到的背景，如下的一些新的研究主題應該被改進： 連接傳熱裝置和溫度應力場的相界面當融化金屬處于液體和固體的臨界狀態(tài)時通過連續(xù)的變形和快速凝固，一種全新的微觀結構可以被獲得。它們影響著材料加工設備抗摩擦裝置的成型。 在高壓場條件下非線性接觸式機械裝置在大范圍內(nèi)組建一個超強力壓力場是材料加工設備的一個基本功能。在強壓力場下設計過程中，將會涉及到設備的設計新理論，例如：非接觸式、非線性摩擦機構。 耦合裝置和在材料加工系統(tǒng)中物理領域內(nèi)的穩(wěn)定性隨著系統(tǒng)的功能越來越多元化；許多限制材料加工進度的傳統(tǒng)技術正在不斷的被改善；系統(tǒng)結構也逐漸變得越來越復雜，系統(tǒng)性能變得越來越好。因為在控制模型中多種交互作用的存在，根據(jù)退耦控制模型而建立綜合框架是必要的；精確的控制基于綜合技術。因此我們需要在重要部位采用具有新功能的原料；例如：尺度功能有傾向的材料是想當
