隨著我國加入世界貿易組織，成為制造業大國，我國和國外的技術交流越來越廣，企業的技術人員不僅要具備專業的知識，而且要具備閱讀英文技術資料、文獻、產品使用說明書的能力。為了使工科學生適應現今社會技術的發展，滿足企業對技術人才知識廣而博的要求，我們編寫了本教材。
全書分5部分（5個部分的劃分參見目錄），共45單元，每個單元包括課文、生詞及專業詞匯注釋、長難句解析、課后練習題、趣味閱讀等內容。本書內容包括機械制圖、機械原理、機械設計、公差、液壓、金屬材料、熱處理、鑄造、鍛壓、焊接、金屬切削機床、刀具、夾具、計算機輔助設計、計算機輔助制造、柔性制造系統、計算機輔助編程、電火花加工、質量控制、數控原理與加工、制造管理等方面的專業英語知識和術語。本書各單元的內容既有系統性的編排，又相互獨立，各個學校可以根據具體情況自行選擇教學內容。
本書由高成秀擔任主編，徐創文擔任主審。參加編寫工作的有：高成秀（PartⅢ、PartV、各單元名人名言、各單元單詞注音），王珺（PartⅡ），楊永萍（Part I中第l～11單元），張紅巖（Part I中第12～14單元，Part1Ⅳ），許萍（每單元后的趣味閱讀）。全書由高成秀統稿。
通過本書，希望讀者能夠對有關機械零件及其加工方法和過程的知識，以及有關機械零件及其加工方法和過程的專業英語有一個全面的認識，希望本書能夠幫助讀者學到知識，并且從中獲得學習的動力和樂趣。
本書在編寫過程中，得到了多位老師和同仁的大力支持，在此向他們表示衷心的感謝。
由于編者水平有限，難免會有不妥之處，歡迎讀者批評指導。

In those days，even the finest glass lenses，ground by the best professional lens-makers，could magnify things only ten times．They were used mainly for reading，by people with weak eyesight．But Leeuwenhoek was not satisfied with the store-bought lenses．He knew very well that he could make better odes himself He worked hard in his store in the daytime．At night，he would hurry home and spend long hours over his work table，grinding and polishing tiny bits of glass no bigger than a large dot．
He made hundreds and hundreds of these lenses．His skill improved with practice，and finally he Was able to make lenses that could magnify a flea So that it looked 150 times as large as it actually was．Leeuwenhoek made gold or silver flames for his lenses，and sometimes he attached handles to them So that he could carry them around and examine things through them．
Then he thought of something better．He mounted a lens on a little frame and put a mirror beneath it to reflect the light up into the lens．On a strip of clear glass between the lens and the mirror, he placed whatever he wanted to examine：the eye of a fly，a speck of pepper or a bit of skin．The magnifying glass was now a microscope．Forty years before he Was born，another Dutch lens-maker had perfected a microscope scope with two lenses，but Leeuwenhoeks single lens machine was far better and easier to use．
