河南科技学院2009届本科毕业论文（设计）论文题目数码相机面壳注塑模的设计与数控加工学生姓名刘佳伟所在院系机电学院所学专业机电技术教育导师姓名王振宁完成时间2009年5月20日1摘要Pro/ENGINEER及MasterCAM是当前国内外模具设计与数控加工领域中使用最为广泛的CAD/CAM软件。二者的功能各有优缺点,联合应用可提高模具设计及其数控加工的质量和效率。本论文阐述了用Pro/ENGINEER软件进行数码相机面壳的模具设计,然后将图形数据转换到MasterCAM软件中进行数控编程的具体实现方法,并利用MasterCAM软件生成数控加工代码并输送到加工中心或数控铣床进行加工的方法和主要工艺。通过此次注塑模的设计，掌握了相关模具设计的主要步骤，对于CAD/CAM软件应用方面有了进一步的提高。关键词注塑模，模具设计，刀具路径，数控加工，凸、凹模2ThedesignandnumericalcontrolmachineprocessingofthedigitalcameracoverpaneljetmouldAbstractPro/ENGINEERandMasterCAMarewidelyusedindomesticandinternationalmouldsdesignandNCmachiningintheCAD/CAMrealm.ThecombinedapplicationofthesetwosoftwarescanimprovemoldsdesignanditsNCmachiningsqualityandefficiency.ThispaperexpatiatesthemethodandmaintechniquestoproceedthemoldsdesignoftheDigitalcameracoverpanelwiththePro/ENGINEERsoftware,thenconvertthegraphicsdatatoMasterCAMsoftwaretoproceedtheNCprogramme,andapplytheMasterCAMsoftwaretocreatetheNCmachiningcodeandtransportittothecontrolsystemoftheNCmachiningcenterortheNCmillingmachineforprocessing.Throughdesignthejetmould,Ihasgraspedthemainstepofthecorrelationmolddesigns,andalsohasthefurtherenhancementontheCAD/CAMsoftwareapplication.KeywordsJetmould,Mouldsdesign,Toolpath,NCmachining,Punch–die3目录1绪论..............................................................42设计要求..........................................................43用Pro/ENGINEER软件对数码相机面壳进行三维造型.....................43.1数码相机面壳的工艺性分析...................................53.1.1数码相机面壳结构尺寸.................................53.1.2数码相机面壳的精度...................................53.1.3数码相机面壳的材料...................................54用Pro/ENGINEER软件对数码相机面壳进行模具设计.....................54.1模具设计...................................................64.1.1调入模具参考模型.....................................64.1.2设置收缩率...........................................64.1.3设计毛坯工件.........................................64.1.4设计分型面...........................................64.1.5分割体积块...........................................74.1.6抽取模具元件.........................................74.1.7铸模.................................................74.1.8开模.................................................74.2模具的工艺性分析..........................................104.2.1模具的结构尺寸......................................104.2.2模具的精度..........................................104.2.3模具的材料..........................................105从Pro/ENGINEER系统转出IGES数据文件.............................106MasterCAM系统转入IGES数据文件..................................107用MasterCAM软件对数码相机面壳进行数据加工.......................107.1对数码相机面壳凹模进行数控加工............................107.2对数码相机面壳凸模进行数控加工............................188结束语...........................................................27致谢...............................................................27参考文献...........................................................28
