Assisting this effect by using the production of MQL and the cutting fluid method to analyze and compare. The contents analyze and inspect the differences when using nano- fluid, water-based fluid and MQL through the usage of wheel leading and wear, grinding force, surface of workpiece and roughness, also to analyze the diversification. The conclusion of this experiment is that MQL is the most effective to reduce wheel leading, and is most prone to achieve better surface of workpiece and roughness than the general wet grinding. Different kinds of cutting fluid also use the method of MQL in order to most effectively reduce roughness. When using MQL, we acquire a flatter workpiece in order that we could economize the finished cost and to enhance efficiency.目 錄 口試委員會審定書…………………………………………………………………….Ⅰ 誌謝…………………………………………………………………………………….Ⅱ 中文摘要……………………………………………………………………………….Ⅲ Abstract…………………………………………………………...……........................Ⅳ 目錄…………………………………………………………………………………….Ⅴ 圖目錄………………………………………………………………………………….Ⅶ 表目錄………………………………………………………………………………….Ⅸ 符號對照表…………………………………………………………………….………Ⅹ 第一章 緒論……………………………………………………………………………1 1.1研究背景與動機………………………………………………………………1 1.2 文獻回顧……………………………………………………………………...2 1.3 研究目的……………………………………………………….......................6 1.4 本文內容……………………………………………………….......................6 第二章 相關理論………………………………………………………………………7 2.1磨削原理………………………………………………………………………7 2.2磨削力中切削力和摩擦力的分析……………………………………………7 2.3鈦合金性質…………………………………………………………………..13 2.3.1添加元素對鈦合金相的影響………………………………………….13 2.3.2鈦合金的種類………………………………………………………….14 2.3.3鈦合金的加工特性…………………………………………………….16 2.4切削液與MQL之背景及應用……………………………………………...21 2.5奈米顆粒基本性質…………………………………………………………..23 2.6表面粗糙度的表示方法……………………………………………………..26 2.6.1表面組織之定義……………………………………………………….26 2.6.2表面粗糙度的表示法…………………………………………….……27 第三章 實驗設備及方法………………………………………………………….….30 3.1 實驗設備……………………………………………………………….……30 3.2 實驗方法…………………………………………………………………….37 第四章 實驗結果與討論……………………………………………………………..41 4.1切削液對砂輪磨耗的影響…………………………………………….…….41 4.2切削液對磨削力的影響……………………………………………………..45 4.2.1 切削液對切線磨削力的影響…………………………………………45 4.2.2 切削液對摩擦係數的影響……………………………………………50 4.3切削液對工件表面影響……….………………………………..…………...51 4.3.1切削液對加工面的影響……………………………………………….51 4.3.2切削液對表面粗糙度的影響………………………………………….54 第五章 結論和未來展望……………………………………………………………..60 參考文獻………………………………………………………………………………615227772 bytesapplication/pdfen-USTi-6Al-4V微量噴霧奈米切削液Ti-6A1-4VMQLnano-fluid奈米切削液對磨削鈦合金的影響The Effects of Cutting Fluid with Nano Particles on the Grinding Ti Alloysthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/61054/1/ntu-96-R94522726-1.pdf
