機(jī)械專業(yè)外文翻譯-木工機(jī)械的發(fā)展及特點(diǎn)-免費(fèi)閱讀
【正文】 21世紀(jì)初，機(jī)械制造業(yè)的重要特征表現(xiàn)在它的全球化、網(wǎng)絡(luò)化、虛擬化、智能化以及環(huán)保協(xié)調(diào)的綠色制造等。據(jù)美國、日本和歐洲等發(fā)達(dá)國家的統(tǒng)計(jì)， 1975～ 1995年機(jī)械零件的種類增加了 40％～ 50％，而 75％～ 85％的工作人員不直接與材料打交道，轉(zhuǎn)與信息打交道。在 “激光加工中的傳感器 ”一文中指出，激光加工本身是一種 “盲過程 ”，它只加工一個(gè)點(diǎn)，為了獲得所需形狀，需要通過檢測來控制，激光加工是一種侵蝕過程，其形態(tài)需要通過傳感器檢測和控制。在 “激光加工的傳感器 ”和“表面粗糙度與表面形貌學(xué) ”兩篇論文中，則完全以檢測為主線來進(jìn)行討論。美國由于近年來缺乏對(duì)制造科 學(xué)的重視，使他們許多產(chǎn)品缺乏競爭力。 為了適應(yīng)市場經(jīng)濟(jì)，重振我國機(jī)械制造業(yè)，很有必要重新認(rèn)識(shí)機(jī)械制造業(yè)，了解當(dāng)前國際上機(jī)械制造業(yè)和 21世紀(jì)初機(jī)械制造業(yè)發(fā)展的特點(diǎn)和今后的趨勢。s four little development in a large extent, with their emphasis on manufacturing technology. These countries and regions around the world attach great importance to hightech patents will buy it back, through the manufacturing technology, The formation of unique, special, high product, the first to occupy the world market. This is the reason they can rise off the knowhow. Machinery manufacturing industry to be the leading information science, materials science, to transform itself。 the other hand, information science, materials science, must also rely on manufacturing technology to achieve new development. For example, in the development of puters, the most crucial issue is the high density largescale integrated circuits and memory device production, they are dependent on manufacturing technology development. The United States, Japan and other countries experts have manufacturing science and information science, materials science, biological science together with as the four pillars of the contemporary era of science. The United States due to the lack of manufacturing in recent years, the importance of science, so many of their products unpetitive. To this end, the . government has approved the Advanced Manufacturing Program in 1996 as the sole focus of the national budget to support scientific and technological areas, which has caused the United States, Japan, and Europe in the new round of petition in manufacturing technology. To reunderstanding of mechanical manufacturing industry, still contains another sense. It is not in the traditional sense of the machinery, the socalled machining. It is a mechanical, electronic, optical, information science, materials science, biological science, laser science, management and the latest achievements in integrating a new technology and new industries. Detection technology is the development of modern machine manufacturing technology a fundamental guarantee for automated production in much of the information through testing to provide production of various failures appear to be discovered through detection and prevention, the need to rely on detection accuracy is also guaranteed. There is no reliable test would be no modernization and automation, not to mention high efficiency and quality. In this annual meeting, the few articles about the new developments in assembly systems, in both papers stressed that in order to meet the needs
