制造業(yè)是現代國民經濟和綜合國力的重要支柱，其生產總值一般占一個國家國內生產總值的20%~55%。在一個國家的企業(yè)生產力構成中，制造技術的作用一般占60%左右。專家認為，世界上各個國家經濟的競爭，主要是制造技術的競爭。其競爭能力最終體現在所生產的產品的市場占有率上。隨著經濟技術的高速發(fā)展以及顧客需求和市場環(huán)境的不斷變化，這種競爭日趨激烈，因而各國政府都非常重視對先進制造技術的研究。
1?當前制造科學要解決的問題
當前制造科學要解決的問題主要集中在以下幾方面：
（1）制造系統(tǒng)是一個復雜的大系統(tǒng)，為滿足制造系統(tǒng)敏捷性、快速響應和快速重組的能力，必須借鑒信息科學、生命科學和社會科學等多學科的研究成果，探索制造系統(tǒng)新的體系結構、制造模式和制造系統(tǒng)有效的運行機制。制造系統(tǒng)優(yōu)化的組織結構和良好的運行狀況是制造系統(tǒng)建模、仿真和優(yōu)化的主要目標。制造系統(tǒng)新的體系結構不僅對制造企業(yè)的敏捷性和對需求的響應能力及可重組能力有重要意義，而且對制造企業(yè)底層生產設備的柔性和可動態(tài)重組能力提出了更高的要求。生物制造觀越來越多地被引入制造系統(tǒng)，以滿足制造系統(tǒng)新的要求。?
（2）為支持快速敏捷制造，幾何知識的共享已成為制約現代制造技術中產品開發(fā)和制造的關鍵問題。例如在計算機輔助設計與制造(CAD／CAM)集成、坐標測量(CMM)和機器人學等方面，在三維現實空間(3-Real?Space)中，都存在大量的幾何算法設計和分析等問題，特別是其中的幾何表示、幾何計算和幾何推理問題；在測量和機器人路徑規(guī)劃及零件的尋位(如Localization)等方面，存在C-空間
(配置空間Configuration?Space)的幾何計算和幾何推理問題；在物體操作(夾持、抓取和裝配等)描述和機器人多指抓取規(guī)劃、裝配運動規(guī)劃和操作規(guī)劃方面則需要在旋量空間(Screw?Space)進行幾何推理。制造過程中物理和力學現象的幾何化研究形成了制造科學中幾何計算和幾何推理等多方面的研究課題，其理論有待進一步突破，當前一門新學科--計算機幾何正在受到日益廣泛和深入的研究。
（3）在現代制造過程中，信息不僅已成為主宰制造產業(yè)的決定性因素，而且還是最活躍的驅動因素。提高制造系統(tǒng)的信息處理能力已成為現代制造科學發(fā)展的一個重點。由于制造系統(tǒng)信息組織和結構的多層次性，制造信息的獲取、集成與融合呈現出立體性、信息度量的多維性、以及信息組織的多層次性。在制造信息的結構模型、制造信息的一致性約束、傳播處理和海量數據的制造知識庫管理等方面，都還有待進一步突破。
（4）各種人工智能工具和計算智能方法在制造中的廣泛應用促進了制造智能的發(fā)展。一類基于生物進化算法的計算智能工具，在包括調度問題在內的組合優(yōu)化求解技術領域中，受到越來越普遍的關注，有望在制造中完成組合優(yōu)化問題時的求解速度和求解精度方面雙雙突破問題規(guī)模的制約。制造智能還表現在：智能調度、智能設計、智能加工、機器人學、智能控制、智能工藝規(guī)劃、智能診斷等多方面。
這些問題是當前產品創(chuàng)新的關鍵理論問題，也是制造由一門技藝上升為一門科學的重要基礎性問題。這些問題的重點突破，可以形成產品創(chuàng)新的基礎研究體系。
2?現代機械工程的前沿科學
不同科學之間的交叉融合將產生新的科學聚集，經濟的發(fā)展和社會的進步對科學技術產生了新的要求和期望，從而形成前沿科學。前沿科學也就是已解決的和未解決的科學問題之間的界域。前沿科學具有明顯的時域、領域和動態(tài)特性。工程前沿科學區(qū)別于一般基礎科學的重要特征是它涵蓋了工程實際中出現的關鍵科學技術問題。
超聲電機、超高速切削、綠色設計與制造等領域，國內外已經做了大量的研究工作，但創(chuàng)新的關鍵是機械科學問題還不明朗。大型復雜機械系統(tǒng)的性能優(yōu)化設計和產品創(chuàng)新設計、智能結構和系統(tǒng)、智能機器人及其動力學、納米摩擦學、制造過程的三維數值模擬和物理模擬、超精度和微細加工關鍵工藝基礎、大型和超大型精密儀器裝備的設計和制造基礎、虛擬制造和虛擬儀器、納米測量及儀器、并聯軸機床、微型機電系統(tǒng)等領域國內外雖然已做了不少研究，但仍有許多關鍵科學技術問題有待解決。
信息科學、納米科學、材料科學、生命科學、管理科學和制造科學將是改變21世紀的主流科學，由此產生的高新技術及其產業(yè)將改變世界的面貌。因此，與以上領域相交叉發(fā)展的制造系統(tǒng)和制造信息學、納米機械和納米制造科學、仿生機械和仿生制造學、制造管理科學和可重構制造系統(tǒng)等會是21世紀機械工程科學的重要前沿科學。
2.1?制造科學與信息科學的交叉--制造信息科學
機電產品是信息在原材料上的物化。許多現代產品的價值增值主要體現在信息上。因此制造過程中信息的獲取和應用十分重要。信息化是制造科學技術走向全球化和現代化的重要標志。人們一方面對制造技術開始探索產品設計和制造過程中的信息本質，另一方面對制造技術本身加以改造，以使得其適應新的信息化制造環(huán)境。隨著對制造過程和制造系統(tǒng)認識的加深，研究者們正試圖以全新的概念和方式對其加以描述和表達，以進一步達到實現控制和優(yōu)化的目的。?
與制造有關的信息主要有產品信息、工藝信息和管理信息，這一領域有如下主要研究方向和內容：
(1)?制造信息的獲取、處理、存儲、傳遞和應用，大量制造信息向知識和決策轉化。
(2)?非符號信息的表達、制造信息的保真?zhèn)鬟f、制造信息的管理、非完整制造信息狀態(tài)下的生產決策、虛擬管理制造、基于網絡環(huán)境下的設計和制造、制造過程和制造系統(tǒng)中的控制科學問題。
這些內容是制造科學和信息科學基礎融合的產物，構成了制造科學中的新分支--制造信息學。
2.2?微機械及其制造技術研究
微型電子機械系統(tǒng)(MEMS)，是指集微型傳感器、微型執(zhí)行器以及信號處理和控制電路、接口電路、通信和電源于一體的完整微型機電系統(tǒng)。MEMS技術的目標是通過系統(tǒng)的微型化、集成化來探索具有新原理、新功能的元件和系統(tǒng)。MEMS的發(fā)展將極大地促進各類產品的袖珍化、微型化，成數量級的提高器件與系統(tǒng)的功能密度、信息密度與互聯密度，大幅度地節(jié)能、節(jié)材。它不僅可以降低機電系統(tǒng)的成本，而且還可以完成許多大尺寸機電系統(tǒng)無法完成的任務。例如用尖端直徑為5μm的微型鑷子可以夾起一個紅細胞；制造出3mm大小能夠開動的小汽車；可以在磁場中飛行的像蝴蝶大小的飛機等。MEMS技術的發(fā)展開辟了技術全新的領域和產業(yè)，具有許多傳統(tǒng)傳感器無法比擬的優(yōu)點，因此在制造業(yè)、航空、航天、交通、通信、農業(yè)、生物醫(yī)學、環(huán)境監(jiān)控、軍事、家庭以及幾乎人們接觸到的所有領域中都有著十分廣闊的應用前景。
微機械是機械技術與電子技術在納米尺度上相融合的產物。早在1959年就有科學家提出微型機械的設想，1962年第一個硅微型壓力傳感器問世。1987年美國加州大學伯克利分校研制出轉子直徑為60~120μm的
硅微型靜電電動機，顯示出利用硅微加工工藝制作微小可動結構并與集成電路兼容制造微小系統(tǒng)的潛力。微機械技術有可能像20世紀的微電子技術那樣，在21世紀對世界科技、經濟發(fā)展和國防建設產生巨大的影響。近10年來，微機械的發(fā)展令人矚目。其特點如下：相當數量的微型元器件(微型結構、微型傳感器和微型執(zhí)行器等)和微系統(tǒng)研究成功，體現了其現實的和潛在的應用價值；多種微型制造技術的發(fā)展，特別是半導體微細加工等技術已成為微系統(tǒng)的支撐技術；微型機電系統(tǒng)的研究需要多學科交叉的研究隊伍，微型機電系統(tǒng)技術是在微電子工藝的基礎上發(fā)展的多學科交叉的前沿研究領域，涉及電子工程、機械工程、材料工程、物理學、化學以及生物醫(yī)學等多種工程技術和科學。
目前對微觀條件下的機械系統(tǒng)的運動規(guī)律，微小構件的物理特性和載荷作用下的力學行為等尚缺乏充分的認識，還沒有形成基于一定理論基礎之上的微系統(tǒng)設計理論與方法，因此只能憑經驗和試探的方法進行研究。微型機械系統(tǒng)研究中存在的關鍵科學問題有微系統(tǒng)的尺度效應、物理特性和生化特性等。微系統(tǒng)的研究正處于突破的前夜，是亟待深入研究的領域。
2.3?材料制備／零件制造一體化和加工新技術基礎
材料是人類進步的里程碑，是制造業(yè)和高技術發(fā)展的基礎。每一種重要新材料的成功制備和應用，都會推進物質文明，促進國家經濟實力和軍事實力的增強。21世紀中，世界將由資源消耗型的工業(yè)經濟向知識經濟轉變，要求材料和零件具有高的性能以及功能化、智能化的特性；要求材料和零件的設計實現定量化、數字化；要求材料和零件的制備快速、高效并實現二者一體化、集成化。材料和零件的數字化設計與擬實仿真優(yōu)化是實現材料與零件的高效優(yōu)質制備／制造及二者一體化、集成化制造的關鍵。一方面，通過計算機完成擬實仿真優(yōu)化后可以減少材料制備與零件制造過程中的實驗性環(huán)節(jié)，獲得最佳的工藝方案，實現材料與零件的高效優(yōu)質制備／制造；另一方面，根據不同材料性能的要求，如彈性模量、熱膨脹系數、電磁性能等，研究材料和零件的設計形式。進而結合傳統(tǒng)的去除材料式制造技術、增加材料式覆層技術等，研究多種材料組分的復合成形工藝技術。形成材料與零件的數字化制造理論、技術和方法，如快速成形技術采用材料逐漸增長的原理，突破了傳統(tǒng)的去材法和變形法機械加工的許多限制，加工過程不需要工具或模具，能迅速制造出任意復雜形狀又具有一定功能的三維實體模型或零件。?
2.4?機械仿生制造
21世紀將是生命科學的世紀，機械科學和生命科學的深度融合將產生全新概念的產品(如智能仿生結構)，開發(fā)出新工藝(如生長成形工藝)和開辟一系列的新產業(yè)，并為解決產品設計、制造過程和系統(tǒng)中一系列難題提供新的解決方法。這是一個極富創(chuàng)新和挑戰(zhàn)的前沿領域。
地球上的生物在漫長的進化中所積累的優(yōu)良品性為解決人類制造活動中的各種難題提供了范例和指南。從生命現象中學習組織與運行復雜系統(tǒng)的方法和技巧，是今后解決目前制造業(yè)所面臨許多難題的一條有效出路。仿生制造指的是模仿生物器官的自組織、自愈合、自增長與自進化等功能結構和運行模式的一種制造系統(tǒng)與制造過程。如果說制造過程的機械化、自動化延伸了人類的體力，智能化延伸了人類的智力，那么，"仿生制造"則可以說延伸了人類自身的組織結構和進化過程。
仿生制造所涉及的科學問題是生物的"自組織"機制及其在制造系統(tǒng)中的應用問題。所謂"自組織"是指一個系統(tǒng)在其內在機制的驅動下，在組織結構和運行模式上不斷自我完善、從而提高對于環(huán)境適應能力的過程。仿生制造的"自組織"機制為自下而上的產品并行設計、制造工藝規(guī)程的自動生成、生產系統(tǒng)的動態(tài)重組以及產品和制造系統(tǒng)的自動趨優(yōu)提供了理論基礎和實現條件。
仿生制造屬于制造科學和生命科學的"遠緣雜交"，它將對21世紀的制造業(yè)產生巨大的影響。
仿生制造的研究內容目前有兩個方面：
2.4.1?面向生命的仿生制造?
研究生命現象的一般規(guī)律和模型，例如人工生命、細胞自動機、生物的信息處理技巧、生物智能、生物型的組織結構和運行模式以及生物的進化和趨優(yōu)機制等；
2.4.2?面向制造的仿生制造?
研究仿生制造系統(tǒng)的自組織機制與方法，例如：基于充分信息共享的仿生設計原理，基于多自律單元協同的分布式控制和基于進化機制的尋優(yōu)策略；研究仿生制造的概念體系及其基礎，例如：仿生空間的形式化描述及其信息映射關系，仿生系統(tǒng)及其演化過程的復雜度計量方法。
機械仿生與仿生制造是機械科學與生命科學、信息科學、材料科學等學科的高度融合，其研究內容包括生長成形工藝、仿生設計和制造系統(tǒng)、智能仿生機械和生物成形制造等。目前所做的研究工作大多屬前沿探索性的工作，具有鮮明的基礎研究的特點，如果抓住機遇研究下去，將可能產生革命性的突破。今后應關注的研究領域有生物加工技術、仿生制造系統(tǒng)、基于快速原型制造技術的組織工程學，以及與生物工程相關的關鍵技術基礎等。?
3?現代制造技術的發(fā)展趨勢
20世紀90年代以來，世界各國都把制造技術的研究和開發(fā)作為國家的關鍵技術進行優(yōu)先發(fā)展，如美國的先進制造技術計劃AMTP、日本的智能制造技術（IMS）國際合作計劃、韓國的高級現代技術國家計劃(G--7)、德國的制造2000計劃和歐共體的ESPRIT和BRITE-EURAM計劃。隨著電子、信息等高新技術的不斷發(fā)展，市場需求個性化與多樣化，未來現代制造技術發(fā)展的總趨勢是向精密化、柔性化、網絡化、虛擬化、智能化、綠色集成化、全球化的方向發(fā)展。
