The main reasons are the basic stamping theory and forming technology, die standardization, die design, and so on. The manufacturing process and equipment of die and mould are still quite different from those of developed countries in industry, which leads to a big gap in life, efficiency, processing precision, production cycle and so on between our country and the developed countries in advanced industry. Modern mold industry is a technology, capital-intensive industry. At present, there are about 250000 mould production plants and more than 1 million employees in China. The annual mold output value is more than 100 billion yuan, and the mould export is nearly 3 billion US dollars, but at present, Compared with the advanced industrial developed countries, the stamping technology in our country is still quite backward. The main reasons are the basic stamping theory and forming technology, die standardization, die design, and so on. There is still a considerable gap between the die manufacturing technology and equipment and the developed countries in industry, which leads to the die and mould life, efficiency, processing precision, production cycle and so on in our country and advanced industrial developed countries. The mold of home is quite different from each other. In recent years, the pace of structural adjustment of die and mould industry has been quickened, which is mainly characterized by large scale, precision and complexity, and the development speed of long-life die and die standard parts is higher than that of the industry as a whole. Therefore, with the development of science and technology, computer technology, information technology, automation technology and other advanced technologies are constantly infiltrating, intersecting and merging into the traditional manufacturing technology, the implementation of its transformation, the formation of advanced manufacturing technology. The level of mould design and manufacturing technology is one of the important marks to measure the level of national product manufacturing, which determines the quality, benefit and development ability of new products to a great extent. The stamping die is an essential process equipment for stamping production, and it is a technology-intensive product. The quality, production efficiency and production cost of stamping parts are directly related to die design and manufacture. It has many unique advantages, such as light weight, high rigidity, high strength, good interchangeability, low cost, easy to realize mechanical automation and high production efficiency, and so on, which is used to produce all kinds of sheet metal parts, has many unique advantages, such as light weight, high rigidity, high strength, good interchangeability, low cost, etc. It is a kind of advanced manufacturing technology which can not be compared with and can not be replaced by other processing methods. It has strong competitiveness in the manufacturing industry and is widely used in automobile, energy, machinery, information, aerospace, and has been widely used in automobile, energy, machinery, information, aerospace, and so on. The production of the national defense industry and daily life. In recent decades, stamping technology has made rapid development, it is not only manifested in many new processes and new technologies in the production of a wide range of applications, such as spinning forming, soft die forming, high-energy forming, and so on. More importantly, people's understanding and mastery of stamping technology has a qualitative leap. Modern stamping production is a kind of large-scale continuous operation manufacturing mode. Due to the participation and involvement of high and new technology, the stamping production mode has evolved from the initial manual operation to the integrated manufacturing step by step. Production process gradually realizes mechanization, automation, and is developing towards intelligent and integrated direction. Realize automatic stamping operation and embody safety High efficiency, saving material and other advantages, has been the development direction of stamping production. Compared with other machining methods, the dimensional accuracy of stamping parts is guaranteed by die. Therefore, the quality of stamping parts is stable and the interchangeability is good. In general, it can directly meet the requirements of assembly and use. In addition, due to the plastic deformation of the material, the internal structure of the metal is improved and the mechanical strength is improved, therefore, the stamping parts have the characteristics of light weight, good stiffness, high precision, smooth appearance, beautiful appearance, and so on. Because of the use of die machining, the stamping process can obtain thin wall, light weight, good rigidity, high surface quality and complex shape which can not be manufactured by other machining methods. Stamping generally does not need to heat the blank, and it does not cut metal as much as cutting, so it is not only energy-saving, but also metal-saving. The material utilization ratio of stamping processing can reach 70% and 85%, so the cost of stamping parts is lower and the economic benefit is higher when the stamping parts are produced in mass production. For the ordinary press can produce dozens of products per minute, and the high-speed press can produce hundreds of pieces per minute, so it is a kind of high-efficiency processing. Method。 Large parts such as car bodies can produce several pieces per minute, while small parts can produce more than 1,000 pieces per minute by high-speed stamping. It is easy to realize mechanization and automation because the blanks processed by stamping are plates or rolls and are generally processed in cold state, so it is more suitable to configure robots to realize unmanned production. In the aspect of product structure: with the complexity of product structure, it will inevitably lead to the complex shape of die parts. The traditional geometric detection method can not adapt to the production of die and mould. The 3D NC measuring machine has been widely used in modern mould manufacturing to measure the geometric quantity of die parts, and the testing methods of die machining process have also made great progress. In addition to measuring the data of complex curved surface with high precision, the three-coordinate CNC measuring machine has good temperature compensation device, reliable anti-vibration protection ability, strict dust removal measures and simple operation steps. It makes it possible to detect automatically on the spot. From the continuous improvement of the quality of industrial products, the production of stamping products is developing in the direction of multi-variety, less batch, complex, large-scale, precision, fast updating speed. Stamping die is developing in the direction of high efficiency, precision, long life and large-scale. In order to adapt to the changes in the market, with the rapid development of computer technology and manufacturing technology, stamping die design and manufacturing technology is being designed by hand, relying on manual experience and conventional machining technology to computer-aided design (CAD),). CNC machining, NC electrical machining as the core of computer-aided design and manufacturing (CAD/CAM) technology change. With the rapid development and organic combination of computer technology, mechanical design and manufacturing technology, a new technology of computer aided design and computer aided manufacturing (CAD/CAM) has been formed. This is the key technology to reform the traditional mode of mold production, is a high-tech, high-efficiency system engineering, it provides users with an effective auxiliary tool in the form of computer software, so that engineers and technicians can use computer to product, Die structure, forming process, NC machining and cost are designed and optimized. Die CAD/CAM can significantly shorten the cycle of die design and manufacture, reduce production cost and improve product quality. It has become a common understanding. With the emergence of powerful professional software and efficient integrated manufacturing equipment, based on 3D modeling and concurrent engineering (CE)-based die CAD/CAM technology is becoming the development direction, it can realize manufacturing and assembly-oriented design. The simulation of forming process and NC machining process is realized, and the design and manufacture are integrated. As for enterprises, with the individuation of demand and the globalization of manufacturing, informatization, the change of internal and external environment of enterprises, the traditional production concept and production organization mode of mould industry have been changed. Modern system management technology is being gradually applied in die and mould enterprises. The application of advanced production management mode makes enterprise production realize low cost, high quality and fast speed, and improve the market competition ability of enterprise. The application of advanced mould manufacturing technology has changed the condition that mould quality depends on man-made factors and is difficult to control, which makes die quality depends on physical and chemical factors, the overall level is easy to control, and mold reproduction ability is strong.  英文資料翻譯 據(jù)統(tǒng)計(jì)資料，模具可帶動(dòng)其相關(guān)產(chǎn)業(yè)的比例大約是1∶100，即模具發(fā)展1億元，可帶動(dòng)相關(guān)產(chǎn)業(yè)100億元。通過(guò)模具加工產(chǎn)品，可以大大提高生產(chǎn)效率，節(jié)約原材料，降低能耗和成本，保持產(chǎn)品高度一致性等。如今，模具因其生產(chǎn)效率高、產(chǎn)品質(zhì)量好、材料消耗低、生產(chǎn)成本低而在各行各業(yè)得到了應(yīng)用，并且直接為高新技術(shù)產(chǎn)業(yè)服務(wù)，特別是在制造業(yè)中，它起著其他行業(yè)無(wú)可替代的支撐作用，對(duì)地區(qū)經(jīng)濟(jì)的發(fā)展發(fā)揮著輻射性的影響。 現(xiàn)代模具行業(yè)是技術(shù)、資金密集型的行業(yè)。目前，中國(guó)約有模具生產(chǎn)廠點(diǎn)25萬(wàn)余家，從業(yè)人員有100多萬(wàn)人，全年模具產(chǎn)值達(dá)1000多億元人民幣，模具出口近30億美元，但是目前，我國(guó)沖壓技術(shù)與先進(jìn)工業(yè)發(fā)達(dá)國(guó)家相比還相當(dāng)落后，主要原因是我國(guó)在沖壓基礎(chǔ)理論及成形工藝、模具標(biāo)準(zhǔn)化、模具設(shè)計(jì)、模具制造工藝及設(shè)備等方面與工業(yè)發(fā)達(dá)國(guó)家尚有相當(dāng)大的差距，導(dǎo)致我國(guó)模具在壽命、效率、加工精度、生產(chǎn)周期等方面與先進(jìn)工業(yè)發(fā)達(dá)國(guó)家的模具相比差距相當(dāng)大。 近年來(lái)，模具行業(yè)結(jié)構(gòu)調(diào)整步伐加快，主要表現(xiàn)為大型、精密、復(fù)雜、長(zhǎng)壽命模具和模具標(biāo)準(zhǔn)件發(fā)展速度高于行業(yè)的總體發(fā)展速度。因此隨著科學(xué)技術(shù)的發(fā)展，計(jì)算機(jī)技術(shù)、信息技術(shù)、自動(dòng)化技術(shù)等先進(jìn)技術(shù)正不斷向傳統(tǒng)制造技術(shù)滲透、交叉、融合，對(duì)其實(shí)施改造，形成先進(jìn)制造技術(shù)。 模具設(shè)計(jì)與制造技術(shù)水平的高低，是衡量一個(gè)國(guó)家產(chǎn)品制造水平高低的重要標(biāo)志之一，在很大程度上決定著產(chǎn)品的質(zhì)量、效益和新產(chǎn)品的開(kāi)發(fā)能力。其中沖壓模具是沖壓生產(chǎn)必不可少的工藝裝備，是技術(shù)密集型產(chǎn)品。沖壓件的質(zhì)量、生產(chǎn)效率以及生產(chǎn)成本等，與模具設(shè)計(jì)和制造有直接關(guān)系。用以生產(chǎn)各種板料零件,具有很多獨(dú)特的優(yōu)勢(shì)，其成形件具有自重輕、剛度大、強(qiáng)度高、互換性好、成本低、生產(chǎn)過(guò)程便于實(shí)現(xiàn)機(jī)械自動(dòng)化及生產(chǎn)效率高等優(yōu)點(diǎn)，是一種其它加工方法所不能相比和不可替代的先進(jìn)制造技術(shù)，在制造業(yè)中具有很強(qiáng)的競(jìng)爭(zhēng)力，被廣泛應(yīng)用于汽車、能源、機(jī)械、信息、航空航天、國(guó)防工業(yè)和日常生活的生產(chǎn)之中。 近幾十年來(lái)，沖壓技術(shù)有了飛速的發(fā)展，它不僅表現(xiàn)在許多新工藝與新技術(shù)在生產(chǎn)的廣泛應(yīng)用上，如：旋壓成形、軟模具成形、高能率成形等，更重要的是人們對(duì)沖壓技術(shù)的認(rèn)識(shí)與掌握的程度有了質(zhì)的飛躍。??現(xiàn)代沖壓生產(chǎn)是一種大規(guī)模繼續(xù)作業(yè)的制造方式，由于高新技術(shù)的參與和介入，沖壓生產(chǎn)方式由初期的手工操作逐步進(jìn)化為集成制造。生產(chǎn)過(guò)程逐步實(shí)現(xiàn)機(jī)械化、自動(dòng)化、并且正在向智能化、集成化的方向發(fā)展。實(shí)現(xiàn)自動(dòng)化沖壓作業(yè)，體現(xiàn)安全、高效、節(jié)材等優(yōu)點(diǎn)，已經(jīng)是沖壓生產(chǎn)的發(fā)展方向。 沖壓加工與其他加工方法相比，沖壓件的尺寸精度由模具來(lái)保證，所以制品質(zhì)量穩(wěn)定，互換性好，在一般情況下可以直接滿足裝配和使用要求。此外，在沖壓加工過(guò)程中由于材料經(jīng)過(guò)塑性變形，金屬內(nèi)部組織得到改善，機(jī)械強(qiáng)度有所提高，所以，沖壓件具有質(zhì)量輕、剛度好、精度高和外表光滑、美觀等特點(diǎn)。 沖壓加工由于利用模具加工，所以可獲得其他加工方法所不能或難以制造的壁薄、質(zhì)量輕、剛性好、表面質(zhì)量高、形狀復(fù)雜的零件。沖壓加工一般不需要加熱毛坯，也不像切削加工那樣大量切削金屬，所以它不但節(jié)能，而且節(jié)約金屬。沖壓加工的材料利用率一般可達(dá)70%—85%，所以沖壓件呈批量生產(chǎn)時(shí)其成本比較低，經(jīng)濟(jì)效益較高。對(duì)于普通壓力機(jī)每分鐘可生產(chǎn)幾十件制品，而高速壓力機(jī)每分鐘可生產(chǎn)幾百上千件，所以它是一種高效率的加工方法。如汽車車身等大型零件每分鐘可生產(chǎn)幾件，而小零件的高速?zèng)_壓則每分鐘可生產(chǎn)千件以上。由于沖壓加工的毛坯是板材或卷材，一般又在冷狀態(tài)下加工，因此較易實(shí)現(xiàn)機(jī)械化和自動(dòng)化，比較適宜配置機(jī)器人來(lái)實(shí)現(xiàn)無(wú)人化生產(chǎn)。 在產(chǎn)品結(jié)構(gòu)方面：隨著產(chǎn)品結(jié)構(gòu)的復(fù)雜，必然導(dǎo)致模具零件形狀的復(fù)雜。傳統(tǒng)的幾何檢測(cè)手段已無(wú)法適應(yīng)模具的生產(chǎn)。現(xiàn)代模具制造已廣泛使用三坐標(biāo)數(shù)控測(cè)量機(jī)進(jìn)行模具零件的幾何量的測(cè)量，模具加工過(guò)程的檢測(cè)手段也取得了很大進(jìn)展。三坐標(biāo)數(shù)控測(cè)量機(jī)除了能高精度地測(cè)量復(fù)雜曲面的數(shù)據(jù)外，其良好的溫度補(bǔ)償裝置、可靠的抗振保護(hù)能力、嚴(yán)密的除塵措施以及簡(jiǎn)便的操作步驟，使得現(xiàn)場(chǎng)自動(dòng)化檢測(cè)成為可能。 從工業(yè)產(chǎn)品質(zhì)量的不斷提高，沖壓產(chǎn)品生產(chǎn)正呈現(xiàn)多品種、少批量，復(fù)雜、大型、精密，更新?lián)Q代速度快的變化特點(diǎn)，沖壓模具正向高效、精密、長(zhǎng)壽命、大型化方向發(fā)展。為適應(yīng)市場(chǎng)變化，隨著計(jì)算機(jī)技術(shù)和制造技術(shù)的迅速發(fā)展，沖壓模具設(shè)計(jì)與制造技術(shù)正由手工設(shè)計(jì)、依靠人工經(jīng)驗(yàn)和常規(guī)機(jī)械加工技術(shù)向以計(jì)算機(jī)輔助設(shè)計(jì)（CAD）、數(shù)控切削加工、數(shù)控電加工為核心的計(jì)算機(jī)輔助設(shè)計(jì)與制造（CAD/CAM）技術(shù)轉(zhuǎn)變。 計(jì)算機(jī)技術(shù)、機(jī)械設(shè)計(jì)與制造技術(shù)的迅速發(fā)展和有機(jī)結(jié)合，形成了計(jì)算機(jī)輔助設(shè)計(jì)與計(jì)算機(jī)輔助制造（CAD/CAM）這一新型技術(shù)。這是改造傳統(tǒng)模具生產(chǎn)方式的關(guān)鍵技術(shù)，是一項(xiàng)高科技、高效益的系統(tǒng)工程，它以計(jì)算機(jī)軟件的形式為用戶提供一種有效的輔助工具，使工程技術(shù)人員能借助計(jì)算機(jī)對(duì)產(chǎn)品、模具結(jié)構(gòu)、成形工藝、數(shù)控加工及成本等進(jìn)行設(shè)計(jì)和優(yōu)化。模具CAD/CAM能顯著縮短模具設(shè)計(jì)及制造周期、降低生產(chǎn)成本、提高產(chǎn)品質(zhì)量已成為人們的共識(shí)。 隨著功能強(qiáng)大的專業(yè)軟件和高效集成制造設(shè)備的出現(xiàn)，以三維造型為基礎(chǔ)、基于并行工程（CE）的模具CAD/CAM技術(shù)正成為發(fā)展方向，它能實(shí)現(xiàn)面向制造和裝配的設(shè)計(jì)，實(shí)現(xiàn)成形過(guò)程的模擬和數(shù)控加工過(guò)程的仿真，使設(shè)計(jì)、制造一體化。 對(duì)于企業(yè)來(lái)說(shuō)：隨著需求的個(gè)性化和制造的全球化、信息化，企業(yè)內(nèi)部和外部環(huán)境的變化，改變了模具業(yè)的傳統(tǒng)生產(chǎn)觀念和生產(chǎn)組織方式?，F(xiàn)代系統(tǒng)管理技術(shù)在模具企業(yè)正得到逐步應(yīng)用，先進(jìn)生產(chǎn)管理模式的應(yīng)用使得企業(yè)生產(chǎn)實(shí)現(xiàn)了低成本、高質(zhì)量和快速度，提高了企業(yè)市場(chǎng)競(jìng)爭(zhēng)能力。 模具先進(jìn)制造技術(shù)的應(yīng)用改變了傳統(tǒng)制模技術(shù)模具質(zhì)量依賴于人為因素，不易控制的狀況，使得模具質(zhì)量依賴于物化因素，整體水平容易控制，模具再現(xiàn)能力強(qiáng)。
