JSB-11腔体配合件数数控加工工艺及编程摘要数控技术，是采用数字控制的方法对某一工作过程实现自动控制的技术。它所控制的通常是位置、角度、速度等机械量和与机械能量流向有关的开关量。数控的产生依赖于数据载体和二进制形式数据运算的出现。而数控铣床是在普通铣床上集成了数字控制系统，可以在程序代码的控制下较精确地进行铣削加工的机床。本文为配合零件的编程与加工，通过数控铣床的加工，针对具体的零件，进行了工艺方案的分析，加工方案的确定，刀具和切削用量的选择，确定加工顺序和加工路线，数控加工程序编制。本文主要从三维模型的建造、加工工艺分析和机床编程的一般步骤着手，提高我对CAD/CAM软件的使用与认识、提高我的读图绘图能力。最后通过自动编程与加工，希望能在过程中发现更好的编程方法和加工方法，提高效率，而且运用于实际工作中能够更深入的了解数控机床的加工特点。随着我国综合国力的进一步加强和加入世贸组织。我国经济全面与国际接轨，并逐步成为全球制造中心，我国企业广泛应用现代化数控技术参与国际竞争。数控技术是制造实现自动化，集成化的基础，是提高产品质量，提高劳动生产率不可少的物资手段。关键词：腔体；配合件；数控加工AbstractNumericalcontroltechnology,istheuseofdigitalcontrolmethodforacertainprocessofautomaticcontroltechnology.Itusuallycontrolstheposition,Angle,speedandothermechanicalquantitiesandtheflowofmechanicalenergyrelatedtotheswitchquantity.Theproductionofnumericalcontroldependsontheemergenceofdatacarrierandbinarydataoperation.CNCmillingmachineisintheordinarymillingmachinesetintoadigitalcontrolsystem,canbecontrolledintheprogramcodemoreaccuratemillingmachine.Inordertocooperatewiththeprogrammingandprocessingofparts,throughtheCNCmillingmachineprocessing,forthespecificparts,theanalysisoftheprocessplan,thedeterminationoftheprocessingplan,thechoiceofcuttingtoolsandcuttingparameters,determinetheprocessingsequenceandprocessingroute,CNCmachiningprogramming.Thispapermainlystartsfromtheconstructionof3dmodel,theanalysisofprocessingtechnologyandthegeneralstepsofmachinetoolprogramming,soastoimprovemyuseandunderstandingofCAD/CAMsoftwareandmyabilityofreadinganddrawing.Finally,throughautomaticprogrammingandprocessing,Ihopetofindbetterprogrammingmethodsandprocessingmethodsintheprocess,improveefficiency,andcanbeusedintheactualworktohaveadeeperunderstandingofthemachiningcharacteristicsofCNCmachinetools.WiththefurtherstrengtheningofChina'scomprehensivenationalstrengthandaccessiontothewto.China'seconomyisfullyinlinewithinternationalstandards,andgraduallybecomeaglobalmanufacturingcenter,China'senterpriseswidelyusemodernCNCtechnologytoparticipateininternationalcompetition.CNCtechnologyisthebasisofmanufacturingautomation,integration,istoimproveproductquality,improvelaborproductivityindispensablematerialmeans.Keywords:lumen;Matingparts;Thencmachining目录摘要...............................................................1第一章绪论........................................................21.1数控技术发展及现状..........................................21.2本课题研究的目的及意义......................................31.3课题的主要内容.............................................3第二章零件的工艺分析...............................................52.1零件图工艺分析..............................................52.2零件定位基准选择............................................62.3零件加工工艺规程分析.......................................7第三章运用pro-E建造三维模型.....................................103.1pro-E简单介绍.......................
