摘要本文主要论述了利用MasterCAM8.0软件进行手机模型的设计、加工工艺的分析模拟加工和利用数控机床进行数控加工。MasterCAM可以设计出较为复杂的实体曲面造型。通过MaterCAM8.0软件的实体造型模块进行手机模型的设计。在软件中进行手机模型的虚拟操作并生成NC仿真程序。在对手机模型加工前，首先分析刀具路径是否合理，再进行对手机模型进行加工工艺分析，并学习机床操作，减少对数控机床的错误操作，保证加工的成功率，最后通过数控铣床加工出手机模型。此外，还介绍了数控铣床的操作方法和加工过程的注意事项等。并对加工手机模型刀具大小进行分析，以及判断走刀路径的合理性。由实践得出，在数控加工过程中，根据手机模型图的精度要求，合理安排刀具路径以及刀具参数，保证加工顺利完成，并减少刀具损耗。关键词：手机模型；Mastercam；数控编程；数控加工IABSTRACTThisarticlediscussesthedesignofthecellphonemodelsusingMasterCAM8.0softwareandCNCmachining.MasterCAMcandesignamorecomplexsolidsurfacemodeling.MobilephonemodelsaredesignedwithsolidmodelingmoduleofMaterCAM8.0software，ConductingvirtualoperatingofphonemodelsinthesoftwareandgeneratingsimulationprogramofNC.Beforeworkingonthephonemodel，Firstly,thetoolpathisreasonable，thenAnalyzingthephonemodelprocess，andlearningmachineoperator，reducingerroneousoperationofCNCmachinetools，toensurethesuccessrateofprocessing，Finally,thephonemodelwasprocessedbyCNCmillingmachines.ItalsodescribesoperatingmethodsofCNCmillingandtheprecautionsofprocessing,etc.Analyzingtoolsizetoprocessingphonemodelandjudgethereasonablenessofthepathoftheknifewalking.Derivedfromthepractice,legitimatelyarrangingtoolpathandtoolparametersbasedontheaccuracyrequirementsofPhonemodeldiagramduringCNCmachiningprocess.Ensurecompletingtheprocessingsuccessfully，andreducewearandtearoftool.Keywords：Phonemodels；Mastercam；NCProgramming；numericalcontrolmanufacturingII目录第一章绪论.....................................................................................................................................11.1引言..............................................................................................................................................11.2CAD/CAM技术的发展...........................................................................................................11.3选题背景与主要研究内容......................................................................................................21.3.1选题背景、目的及意义...................................................................................................21.3.2本课题的主要工作..............................................................................................21.4本文结构.....................................................................................................................................3第二章基于Mastercam的手机模型设计....................................................................42.1Mastercam软件介绍................................................................................................................42.2手机模型数据的来源...............................................................................................................42.3Mastercam软件建模................................................................................................................42.3.1手机机身的设计................................................................................................................42.3.2手机按键的...
