This leads to the strict quality requirements of tool design. It is a significant way to improve the competitive capacity of a company that developing the performance, reliability and quality of tools, shortening design period and lowering design cost. Based on the couple of the CAD technology and traditional tool design technology, a common 3D design platform of solid carbide end mills is generated in order to mix some gaps within the traditional design methods, as well as to meet the requirement in machine design.The solid carbide end mills are classified according to the characteristics of CAD modeling. Furthermore, the geometrical topological relations within the parameters used in solid carbide end mills parametric modeling are induced. The mathematical models which are suitable for software development have been established.A solution for the solid carbide end mills is proposed. Based on standard part library, case-based reasoning technology, KBE/UGKF technology and secondary development technology, the integrated scheme for the solid carbide end mills is established, which can improve efficiency and quality of tool design.Based on UG, Visual Studio 2008 and SQL Server 2005, the solid carbide end mills design system is developed. The complicated data treatment can be preceded by the database software and the linking technology of ADO.NET, which is to realize the link between UG system and database. By using KBE/UGKF technology, the intelligent design for the solid carbide end mills is realized. The UG NX Open technology is conducted in the system development. The dynamic-link library (DLL) is created with the technique of the Common application programming interface (API) for Microsoft C# and the second development of UG NX. Some functions, such as case searching, parameters calculation, aided design, three-dimensional modeling, two-dimensional drawing automatically and machining simulation of the solid carbide end mills can be realized in the system. 【關(guān)鍵詞】立銑刀 CAD 數(shù)學(xué)模型 二次開發(fā) 【英文關(guān)鍵詞】End Mill CAD Mathematical Model Secondary Development 【目錄】整體硬質(zhì)合金立銑刀CAD技術(shù)研究 摘要 9-10 ABSTRACT 10-11 第1章 緒論 12-22 1.1 研究背景 12 1.2 國(guó)內(nèi)外研究現(xiàn)狀綜述 12-20 1.2.1 整體硬質(zhì)合金立銑刀研究現(xiàn)狀 12-14 1.2.2 刀具CAD技術(shù) 14-19 1.2.3 數(shù)字化設(shè)計(jì)和參數(shù)化設(shè)計(jì)技術(shù) 19-20 1.3 研究的目的及意義 20 1.4 論文主要研究?jī)?nèi)容 20-22 第2章 整體硬質(zhì)合金立銑刀幾何建模 22-30 2.1 整體立銑刀主要結(jié)構(gòu) 22-23 2.2 立銑刀螺旋刃線數(shù)學(xué)模型 23-26 2.3 立銑刀螺旋面數(shù)學(xué)模型 26-28 2.4 立銑刀頭部數(shù)學(xué)模型 28-29 2.5 本章小結(jié) 29-30 第3章 整體硬質(zhì)合金立銑刀設(shè)計(jì)的求解方案 30-42 3.1 立銑刀設(shè)計(jì)的基本信息 30 3.2 整體硬質(zhì)合金立銑刀求解方案的構(gòu)建 30-40 3.3 本章小結(jié) 40-42 第4章 整體硬質(zhì)合金立銑刀CAD系統(tǒng)設(shè)計(jì) 42-64 4.1 UG二次開發(fā)技術(shù) 42-48 4.1.1 系統(tǒng)開發(fā)環(huán)境 42-43 4.1.2 UG NX二次開發(fā)平臺(tái) 43-47 4.1.3 開發(fā)語(yǔ)言的選擇 47-48 4.1.4 數(shù)據(jù)庫(kù)的選擇 48 4.2 硬質(zhì)合金立銑刀CAD系統(tǒng)設(shè)計(jì) 48-60 4.2.1 系統(tǒng)特點(diǎn)分析 48-49 4.2.2 系統(tǒng)功能及主要模塊 49-53 4.2.3 系統(tǒng)體系結(jié)構(gòu) 53-55 4.2.4 工程文件 55-58 4.2.5 人機(jī)界面 58-60 4.3 系統(tǒng)數(shù)據(jù)庫(kù)設(shè)計(jì) 60-62 4.4 軟件架構(gòu) 62-63 4.5 本章小結(jié) 63-64 第5章 整體硬質(zhì)合金立銑刀幾何建模系統(tǒng)的實(shí)現(xiàn) 64-74 5.1 設(shè)置環(huán)境變量 64-65 5.2 立銑刀設(shè)計(jì)實(shí)現(xiàn) 65-72 5.3 本章小結(jié) 72-74 結(jié)論與展望 74-76 參考文獻(xiàn) 76-82 致謝 82-84 攻讀學(xué)位期間發(fā)表的學(xué)術(shù)論文及取得的成果 84-85 學(xué)位論文評(píng)閱及答辯情況表 85
