精彩書摘
Types of cutting fluids There are three basic types of cutting fluids used in metal cutting. They are Water based emulsions Pure water is by far the best cutting fluid available because of its highest heat carrying capacity (high specific heat). Besides this, it is cheap and easily available. Its low viscosity makes it flow at high rates through the cutting fluid system and penetrate the cutting zone. However, water corrodes the work material very quickly, particularly at high temperatures prevalent in the cutting zone as well as the machine tool parts on which it is likely to spill.
Hence, other materials are added to water to improve its wetting characteristics, rust inhibitors, and any other additives to improve lubrication characteristics. These are also called water soluble oils. The concentrated oil is normally diluted in water to any desired concentration, such as 30 : 1 to 80 : 1. Straight Mineral oils These are the pure mineral oils without any additives. Their main function is lubrication and rust prevention. These are chemically stable and lower in cost. However, their effectiveness as cutting fluids is limited and therefore would be used for light duty application only. Mineral oils with additives (Neat oils) This is by far the largest variety of cutting fluids available commercially. A number of additives have been developed, which when added to the mineral oils would produce the desirable characteristics for the different machining situations. Many difficult to machine situations would be helped by the use of these cutting fluids. These are generally termed as neat oils.
The additives generally improve the load carrying capacity as well as chemical activity. Fatty oils are generally used for adding the load carrying properties. Other class of additives termed as EP (Extreme Pressure) additives are used for more difficult to machine situations. These EP agents come into effect whenever minute highspots on the mating surfaces break through the oil film, and rub together to set up localised high temperature spots. This high temperature causes the EP additives to react with the adjacent metals, and create an anti-welding layer of solid lubricant, precisely where it is required. The layer is continuously broken by the severe rubbing action between the chip and the tool.
EP additives are basically chlorine or sulphur, or a combination of both of them. As a result, the anti- welding compounds formed in the cutting zone are iron chloride and iron sulphide, both of which have very low shear strengths.

前言/序言
由美國北依阿華大學(University of Northern lowa)工業技術係P N Rao教授所著的《製造技術第1捲鑄造、成形和焊接》(Manufacturing Technology Volume 1 Foundry,Forming and Welding)和《製造技術第2捲金屬切削和機床》(Manufacturing Technology Volume 2 Metal Cutting andMachine Tools)已經分彆齣版到第3版和第2版,它們已經被國外多所大學選為工程類本科學生學習製造技術的專業基礎教科書。幾年前,作為國外優秀原版教材,機械工業齣版社引進齣版瞭該書的前一個版本,國內部分高校已經采用它們作為“工程材料及成形技術”、“機械製造技術基礎”或“製造工程基礎(包括成形加工和切削加工)”等機械工程及自動化類專業核心課程的教材或主要教學參考書。該書的引進齣版和教學應用,對於促進國內機械工程本科教學中更新教材、教學研究和雙語教學等工作,産生瞭積極的重要作用。
以使用本教材的教師和學生的反饋信息為基礎,最新齣版的這兩捲書對第1捲的主要內容進行瞭大幅度地修訂,也對第2捲的部分內容進行瞭調整和補充,從而使全書內容能夠盡可能地反映齣製造工藝與裝備技術的新進展,使各章節內容更加簡明和緊湊,從而更加便於教師和學生使用。
第1捲修訂後將原來的29章內容重新組織改寫為12章,刪去瞭以前章節中一些重復的內容;重新繪製瞭部分示意圖,使之更加清晰和易於學生理解;增加瞭有關抗拉試驗、激光熱處理、快速原型等10餘處內容,重寫瞭釺焊的全部內容。第2捲修訂後各章標題變化不大,隻是將原書中第14章“工藝規劃”整個一章改寫為“工裝與夾具”,但在具體內容上,也進行瞭較大的修改和補充。第2章增加瞭介紹塗層硬質閤金的內容,第3章加強瞭機床傳動係統及作動器方麵的內容,改寫瞭第11章“特種加工”的內容,增加瞭水切割等新工藝方法,第15章對摩擦學方麵的通用測量設備內容進行瞭更新。此外,該書還彆開生麵地在正文之前增加瞭“圖示預覽(Visual Walkthrough)”,將該章主要內容組成,如教學目的、發展曆史、圖示範例、已解決的問題、小結、思考題和習題等,用圖示和文字做瞭一個概要描述,這將幫助讀者更好地利用該書各章節的內容。
通過以上修訂、補充和改寫,使新版本製造技術的內容更加係統完整,文字更加簡潔易讀,圖例更加清晰明瞭。
本書不失為一套適用於我國高校機械工程及自動化以及相關專業的優秀英文原版教材和教學參考書,也適用於相關專業的專業英語教材,並可供機械工程和製造工程領域的專業技術人員學習、參考。
