摘要随着我国科学技术的快速进步和制造业的快速发展,工业生产中自由曲面的加工应用越来越广泛。现代化生产中常采用自动编程技术对复杂曲面进行数控加工。CAXA制造工程师软件是现代化生产中较为常用的CAD/CAM软件之一。本文基于CAXA制造工程师对复杂曲面的数控加工技术进行了研究。研究的具体内容包括以下方面:一、基于CAXA制造工程师环境,研究了复杂曲面粗加工方法、精加工方法以及粗、精加工方法策略的选择问题,在CAXA制造工程师仿真模块创建数控加工的复杂曲面的仿真图形,然后进行仿真加工比较,从中选出更适合的复杂类曲面数控加工方法。二、基于CAXA制造工程师环境,创建针对复杂类曲面在FANUC21iMB型数控系统的加工中心加工时的后置处理器,并生成新的后置处理模块。三、基于CAXA制造工程师环境下的数控仿真和实际加工处理,验证了基于CAXA制造工程师环境下采用数控加工方式对复杂曲面进行加工可以获得更好的加工质量和更高的加工效率,对提高传统数控加工的质量差、效率低的问题具有指导意义。本论文基于CAXA制造工程师的复杂曲面数控加工研究结果,对类似的其它复杂型腔型腔曲面加工也具有良好的借鉴意义。关键词:复杂曲面,CAXA制造工程师.数控加工,后置处理AbstractWiththerapidprogressofscienceandtechnologyinChinaandthedevelopmentofthemanufacturingsector,theindustrialproductioninthefree-formsurfacemachiningapplicationsaremoreandmorewidelyapplied.AutomaticprogrammingtechniquesareoftenusedinmodernproductionCNCmachiningofcomplexsurfaces.CAXAManufacturingEngineerisonesoftwarewidelyusedinmodernproductionCAD/CAMfield.ThepaperisbasedonCAXAManufacturingEngineerstudyingCNCmachiningofcomplexsurface.Thespecificcontentsofthestudyareasfollow:First,basedontheenvironmentofCAXAmanufacturingengineers,tostudycomplexsurfaceroughing,finishingmanufacturingmethods,andcoarse,finishingthechoiceofmethodsandstrategies,CNCmachiningofcomplexsurfacesimulationgraphicscreatedinCAXAthemanufacturingengineerssimulationmodule,andthenthesimulationprocessingcompareandchoosemoresuitableforcomplexclasssurfaceCNCmachiningmethods.Second,basedontheenvironmentofCAXAmanufacturingengineers,tocreatepostprocessorFanuc21iCNCmachiningcenterforcomplexclasssurfacemachining,andgenerateanewpost-processingmodule.Third,basedontheNCsimulationandactualprocessingundertheenvironmentofCAXAManufacturingEngineerenvironment,verifiedthattheCAXAManufacturingEngineerenvironmentCNCmachiningprocessingcangetbetterqualityandhigherprocessingefficiencyofthecomplexsurface-based,toimprovethetraditionalCNCmachiningofpoorquality,lowefficiencyproblemofguidingsignificance.CAXAManufacturingEngineercomplexsurfaceNCmachiningresultsofthisthesis,alsoagoodreferenceforothersimilarthecomplexcavitymoldsurfacemachining.Keywords:complexsurface,CAXA,CNCmachining,post-processing目录第1章绪论.............................................11.1课题研究的背景.............................................11.1.1数控编程及其发展简介.................................11.1.2数控技术的发展趋势...................................21.1.3对我国数控技术及其产业发展的基本估计.................41.1.4CAD/CAM技术的发展概况...............................41.1.5CAXA制造工程师简介及其功能.........................51.2课题研究的目的、意义及内容.................................61.2.1传统复杂曲面加工存在的问题...........................61.2.2课题研究的目的、意义.................................61.2.3课题研究的内容.......................................71.3本章小结..................................................7第2章加工中心自动编程及加工工艺.......................82.1加工中心的...
