前言

　　專(zhuān)業(yè)英語(yǔ)是大學(xué)英語(yǔ)教學(xué)的重要組成部分，是促進(jìn)學(xué)生完成從學(xué)習(xí)過(guò)渡到實(shí)際應(yīng)用的有效途徑。教育部于2007年頒布了《大學(xué)英語(yǔ)課程教學(xué)要求》，該文件中將大學(xué)英語(yǔ)的教學(xué)要求分為三個(gè)不同的層次——一般、較高和更高要求，并分別對(duì)這三個(gè)層次的英文文獻(xiàn)閱讀能力提出了不同的要求。強(qiáng)調(diào)大學(xué)英語(yǔ)課程要保證學(xué)生在整個(gè)大學(xué)期間的英語(yǔ)語(yǔ)言水平穩(wěn)步提高，要能滿足他們專(zhuān)業(yè)知識(shí)的發(fā)展，并提出應(yīng)注重培養(yǎng)自主學(xué)習(xí)能力的教學(xué)思想和實(shí)踐的轉(zhuǎn)變。根據(jù)這個(gè)精神，編者編寫(xiě)本書(shū)，以幫助學(xué)生通過(guò)專(zhuān)業(yè)外語(yǔ)的學(xué)習(xí)能順利閱讀有關(guān)專(zhuān)業(yè)的原版教科書(shū)、參考書(shū)及其他參考資料，并滿足高等院校機(jī)械類(lèi)專(zhuān)業(yè)學(xué)生專(zhuān)業(yè)外語(yǔ)教學(xué)的需要和機(jī)械工程技術(shù)人員學(xué)習(xí)英語(yǔ)的要求?！　∪珪?shū)共精選專(zhuān)業(yè)文章49篇，分為七部分，每部分各有側(cè)重，讀者可根據(jù)自己的專(zhuān)業(yè)領(lǐng)域選取不同部分進(jìn)行閱讀。主要內(nèi)容包括：第一部分8篇，以金屬材料及熱處理方面的文章為主；第二部分包含了9篇有關(guān)機(jī)械零件方面的文章；第三部分的7篇文章則側(cè)重于機(jī)械設(shè)計(jì)理論方面；第四部分的8篇文章為有關(guān)機(jī)械制造技術(shù)的基礎(chǔ)知識(shí)及理論：第五部分是有關(guān)各種先進(jìn)制造技術(shù)方面的6篇文章；第六部分10篇，側(cè)重于機(jī)電控制技術(shù)；第七部分的ll篇文章則屬于擴(kuò)展閱讀，立足于反映出機(jī)械專(zhuān)業(yè)技術(shù)的現(xiàn)狀和發(fā)展趨勢(shì)，同時(shí)選取了部分與電力行業(yè)密切相關(guān)的文獻(xiàn)材料?！　”緯?shū)內(nèi)容新穎、取材精練、難度適中，所選內(nèi)容涵蓋了學(xué)生所學(xué)習(xí)過(guò)的專(zhuān)業(yè)知識(shí)，又有所拓展和延伸，從而既可提高讀者的英語(yǔ)閱讀水平，又能使讀者了解學(xué)科前沿。

章節(jié)摘錄

　　If variables such as cutter geometry and the rigidity of the machine tool and its toolingsetup could be ideally maximized （and reduced to negligible constants）， then the amount ofpower （that is， kilowatts or horsepower） available to the spindle would determine themaximum speeds and feeds possible for any given workpiece material and cutter material. Ofcourse， in reality those other variables are dynamic and not negligible； but there is still acorrelation between power available and feeds and speeds employed.　　Cutting speed may be defined as the rate （or speed） that the material moves past thecutting edge of the tool， irrespective of the machining operation used —— the surface speed. Acutting speed for mild steel， of 100 ft/min （or approx 30 meters/min） is the same whether it isthe speed of the （stationary） cutter passing over the （moving） workpiece， such as in a turningoperation， or the speed of the （stationary） workpiece moving past a （rotating） cutter， such as ina milling operation. What will affect the value of this surface speed for mild steel are thecutting conditions，　　For a given material there will be an optimum cutting speed for a certain set of machiningconditions， and from this speed the spindle speed （RPM） can be calculated.
