数控车配合件工艺与编程

西安航空职业技术学院毕业设计论文-1-配合件的工艺与编程【摘要】数控技术是用数字信息对机械运动和工作过程进行控制的技术,数控装备是以数控技术为代表的新技术对传统制造产业和新兴制造的渗透形成的机电一体化产品,即所谓的数字化装备。数控技术的应用不但给传统制造业带来了革命性的变化,使制造业成为工业化的象征,而且随着数控技术的不但发展和应用领域的扩大他对归计民生的一些重要行业(IT、汽车、医疗、轻工等)的发展起着越来越重要的作用,因为这些行业所需要装备的数字化已是现代发展的大趋势.在我国加入WTO和对外开放进一步深化的新环境下,发展我国数控技术及装备是提高我国制造业信息化水平和国际竞争能力的重要性保证.数控加工与编程毕业设计是数控专业教学体系中构成数控加工技术专业知识及专业技能的重要组成部分，通过毕业设计使我们学会了对相关学科中的基本理论基本知识进行综合运用,同时使对本专业有较完整的系统的认识,从而达到巩固、扩大、深化所学知识的目的,培养和提高了综合分析问题和解决问题的能力以及培养了科学的研究和创新能力。此次的毕业设计主要解决的问题是零件的装夹、刀具的对刀、工艺路线的制订、工序与工步的划分、刀具的选择、切削用量的确定、车削加工程序的编写、机床的熟练操作。关键词：数控车、工艺分析、加工方案、西安航空职业技术学院毕业设计论文-2-Abstract:Numericalcontroltechniqueistousethetechniquethatthefigureinformationcarriesonacontrolvsmachineryrunningandtheoperateprocess,countcontrolanequipageiswiththenumbercontroltechniquefortherepresentative'snewtechniquemakethemachineelectricityintegralwholethatdomainandnewlyarisenmanufacturingpermeateformingtoturnaproducttothetradition,namelytheso-calleddigitizeequips.Thenumbercontroledtechnicalapplicationtonotonlybringtraditionalmanufacturingbusinessrevolutionchange,makethemanufacturingbusinessbecomethesymbolofindustrialization,butalsoalongwithnumbercontroltechnicalnotonlyexpandingofshapeandapplicationrealmhissomeshapesofimportantcrafts(IT,autocar,medicaltreatmentandlightworketc.)inreturningtoaccountpeople'slivelihoodscontainmoreandmoreimportantaction,becausethesecraftsisalreadythebigtrendofmodernshapethedigitizethatneedtobeequiped.Deveolpanourcountrynumberunderthenewsurroundingthatourcountrybuilding-outWTOwithoutwardopentodeepenfurthercontroltechniqueandequipageisexaltationourcountryimportanceassuranceofthemanufacturingbusinessinformation-basedhorizontalandinternationalcompetitivepower.Thenumbercontrolstransformandplaitdistancetograduateadesignisnumbercontroltoconstitutenumbertocontroltheimportantcompositionofprocessingtechnologyprofessionalknowledgeandprofessionalskillfractionintheprofessionalteachingsystem,thedesignofpassingthegraduationmakesthebasictheorythatwelearnedvsrelatedacademicsbasicknowledgeprogresssynthesisusage,makeatthesametimetheunderstandingtohavemorecompletesystemtothisprofession,thushitconsolidationandexpand,deepenthepurposeoflearningtheknowledge,developmentandexaltationcomprehensiveanalysisproblemandproblem-solvingcapabilityanddevelopmentthesearchandinnovationcapabilityofscience.Thistimegraduation'sdesigningtheproblemofmainsettleisthepackingofkitclip,toolangelofforestablishingknife,craftroute,thesequencetreadwithworkoftheselectofcurtate,toolangel,slicetoparedosagetoreallysettle,thewell-trainedoperationofwritingoftruningjobprogram,enginebed.Keywords:CNClathe、Processanalysis、Processingscheme西安航空职业技术学院毕业设计论文-3-目录1数控机床的发展简介..................................................................................................................52数控加工工艺的基本知识..........................................................................................................72.1数控加工工艺的概念...........................................................................................................72.2数控加工工艺过程...............................................................................................................72.3数控加工的特点...................................................................................................................73零件数控加工前的简单分析......................................................................................................83.1零件的基本情况简介...........................................................................................................83.2零件的技术要求...................................................................................................................93.3加工设备的选择...................................................................................................................93.4零件的工艺分析...................................................................................................................93.5基准的选择原则.................................................................................................................104零件数控加工工艺分析............................................................................................................134.1加工方案的确定.................................................................................................................134.2工步的划分.........................................................................................................................134.3加工顺序及进给路线的确定..............................................................................................134.3.1零件加工时需遵守的原则..........................................................................................134.3.2进给路线的确定..........................................................................................................144.4切削液的选择.....................................................................................................................174.5刀具的选择.........................................................................................................................174.6主要工序的安排............................
