Design all functional and physical characteristics to be as simple as possible. : Complexi ty of the design has a direct bearing on production costs. As a general rule, the serv ice life of a part can be extended considerably when the design of the parts is simpleand sturdy. The loadcarrying capacity of a part is more predictable when the designconfiguration is straightforward and uncomplicated. 2. Design for the most economical production method.It is particularly important to keepthe scrap problem in mind. The ratio of the weight of original material required tothe weight of the finished piece provides a clue to possible cost reductions. This is especially true for highvolume production of parts. Weight considerations often result in a reduction of scrap costs as well as a substantial cost savings of machining time. 3. Design for a minimum number of machining operations.The fewer operations necessa ry to complete a part to drawing specifications, the lower the cost. Needless fancy or nonfunctional configurations requiring extra operations and materials should be omitted from the design. Actually, the greatest savings obtained in designing for production usually result from a reduction in the number of separate processing operations required to complete a part. 4. Specify finish and accuracy no greater than are actually needed.Tolerance on finish and on dimensions plays an important part in achieving a practical production design. The specification of needlessly close tolerances and an unreasonable degree of surface roughness always result in excessive and, in some cases, prohibitive cost. 5. Accessibility of different parts or areas. All components and parts of the productshould be accessible to facilitate regular cleaning and maintenance work. Unaccessible areas lend themselves to the accumulation of dirt with the final outcome being corrosion and / or malfunctioning of the product, Crevices, narrow slots, and bolts and nuts located in places where it is difficult to clean, mount, tighten or loosen, or remove them should be avoided. 查看全部↓ 前言/序言 大學英語教學大綱(修訂本)規定大學英語教學分為基礎階段(一至二年級)和應用提高階段(三至四年級)。應用提高階段的教學包括專業英語(Subject.Based English,簡稱SBE)和高級英語(Advanced English,簡稱AE)兩部分。大綱明確指出:“大學英語教學的目的是培養學生具有較強的閱讀能力和一定的聽、說、寫、譯能力,使他們能用英語交流信息。……以適應社會發展和經濟建設的需要。”新世紀對人纔在外語方面提出了更高的要求。抓好大學英語應用提高階段的教學已勢在必行。編寫本教材的目的是幫助理工科學生在應用提高階段進一步發展、鞏固和提高基礎階段已掌握的讀、聽、寫、說、譯五種技能,並使部分有一定口語基礎的學生在聽說能力方面也能有較大的提高,以適應21世紀對高級人纔的需求。 本教材主要適用於已完成基礎階段學習的高等學校理工科本科生,為應用提高階段的必修課和選修課教材,也可用作研究生教學或工程技術人員的外語培訓教材。 全套教材由專業教師和英語教師合作編寫而成。它以英國語言學家H.G.Widdowson的交際法理論為依據,著重解決語言運用能力的培養問題,使學生將基礎階段已掌握的英語語言知識和技能在自己的專業領域中得到進一步實踐和應用,從而達到能以英語為工具獲取和交流信息的教學目的。 null 查看全部↓
