平面凸轮数控编程与加工设计说明书.doc

1本科毕业论文（设计）论文题目：平面凸轮数控编程与加工学生姓名：所在院系：机电学院所学专业：机械制造及其自动化导师姓名：完成时间：2摘要本课题主要研究了平面凸轮数控加工工艺和加工方法，通过选择不同的工艺方案，确定合理的加工刀具和装夹方式及切削用量，重点解决了刀具在加工凸轮时加工顺序的问题。在分析和研究过程中，使用CAXA数控铣软件进行了建模、造型和仿真，生成了加工代码，在数控铣床进行了加工，并进行了对比分析和总结，最后确定了比较合理的加工方案，为实际数控生产加工提供了可靠的依据。关键词：数控加工，平面凸轮，工艺方案，装夹方式，切削用量3PlaneCamCNCMachiningTechnologyProgramToDetermineAbstractThistopichasmainlystudiedthePlaneCamnumericalntrolprocessingcraftandtheprocessingmethod,throughthechoicedifferentcraftplan,determinedthereasonableprocessingcuttingtoolandtheattireclampthewayandthecuttingspecifications,solvedthecuttingtoolwhenprocessedthescoopchannelwiththeworkpiecesurfacetohavetheinterferencequestionwithemphasis.Intheanalysisandtheresearchprocess,usedCAXAnumericalcontrolvehiclesoftwaretocarryonthemodelling,themodellingandthesimulation,hasproducedtheprocessingcode,hascarriedontheprocessinginthenumericalcontrollathe,andcarriedonthecontrasttoanalyzeandtosummarize,finallyhaddeterminedthequitereasonableprocessingplan,hasprovidedthereliablebasisfortheactualnumericalcontrolproductionprocessing.Keywords：NumericalControlProcessing,PlaneCam,Craftdetermination,Theattireclampstheway,Thecuttingspecifications1目录1引言··················································································12数控铣床加工工艺的分析··························································22.1零件图分析.22.2装夹方案分析.32.3加工顺序及走刀路线的确定.32.4刀具选择.33加工工序的确定····································································43.1机床的选择.43.2量具的选择.43.3切削用量选择.43.3.1背吃刀量的选定.53.3.2进给量f的选定.53.3.3切削速度cv的选择.53.4填写加工工艺卡片.64编写加工程序·······································································7编写加工程序的基本步骤.135程序校验··········································································146工件安装与对刀··································································146.1工件安装.146.2对刀.157自动加工并测量修调·····························································168结束语·············································································16致谢··················································································16参考文献·············································································17
