ee铝基复合材料切削加工工艺性能综合评价研究eeee)指导教师：ee[摘要]铝基复合材料具有许多优良性能，如比强度和比刚度高、线膨胀系数小且可调、热稳定性好且耐磨等优点，被广泛应用于航天、航空及汽车工业中。但由于增强相的加入，使得铝基复合材料的切削加工变得很困难，特别是精密和超精密切削更加困难。目前，对铝基复合材料切削加工工艺的研究还不够系统深入，特别是精密和超精密加工工艺的研究在国内尚属空白，国外也未见详实有力的报道。然而，随着航天、航空及民用高技术如高档汽车、体育用品的发展要求，对铝基复合材料的精密和超精密加工技术的需求正日益迫切。本文通过对铝基复合材料的性能、应用、常规加工方法及特种加工方法(如电火花加工、加热辅助切削、电化学加工等)的研究,综结各种加工方法的特点，寻找适合的加工工艺方法。[关键词]铝基复合材料;常规加工;特种加工;刀具eeComprehensiveAssessmentofMetalMatrixCompositesprocessingperformanceee(eeTutor:eeAbstract:Aluminummatrixcompositematerialshavemanyexcellentperformance,Suchasspecificstrengthandhighstiffness,Linearexpansioncoefficientandadjustable,Advantagesofgoodthermalstabilityandwearandsoon.Theyhavebeenwidelyusedinaerospace,aviationandautomobileindustries.However,duetotheenhancedphaseoftheaccessionofthecuttingprocessingofaluminummatrixcompositesbecomeverydifficult,especiallyprecisionandultraprecisioncuttingmoredifficult.Onthecuttingprocessingofaluminummatrixcompositesisnotenoughsystemindepth,especiallyprecisionandultraprecisionmachiningprocessinthecountryisstillblank,foreignnodetailedandpowerfulreporting.However,withtheaerospace,aviationandcivilianhigh-tech,suchasluxurycars,thedevelopmentrequirementsofthesportinggoods,precisionandultraprecisionprocessingtechnologyneedsofthealuminummatrixcompositesareincreasinglyurgent.Inthispaper,theperformanceofaluminummatrixcomposites,applicationofconventionalprocessingmethodsandspecialprocessingmethods(suchasEDM,heat-assistedcutting,electrochemicalmachining,etc.),integratedknotcharacteristicsofthevariousprocessingmethods,findsuitableprocessingprocess.Keywords:Compositematerials,Conventionalmachining,specialmachining,tooleeI目录1.前言.........................................................11.1铝基复合材料简介...................................................11.2铝基复合材料的性能.................................................11.2.1铝基复合材料强度、模量与塑性....................................11.2.2铝基复合材料比刚度和抗磨损性能..................................11.2.3铝基复合材料疲劳与断裂韧性......................................21.2.4铝基复合材料热稳定性及抗大气腐蚀能力............................21.3铝基复合材料的制备工艺.............................................21.3.1粉末冶金法(固态法)..............................................21.3.2压力浸渗工艺(液态法)............................................31.3.3反应自生成法(原位法)............................................31.3.4高能-高速固结工艺...............................................31.3.5半固态搅拌复合制造..............................................31.4铝基复合材料的界面.................................................41.4.1界面结构、界面反应与性能的关系..................................41.4.2界面的优化......................................................41.4.3界面优化和控制界面反应的途径....................................41.4.4复合材料界面效应................................................51.5基体金属的选择.....................................................61.6增强体的选择.......................................................61.7铝基复合材料的主要应用领域.........................................71.8铝基复合材料切削加工工艺性能综合评价研究意义.......................82.铝基复合材料切削加工和加工刀具介绍...............................92.1铝基复合材料的加工特性.............................................92.2SiC/Al复合材料的切削性能研究.......................................92.2.1SiC/Al复合材料简介............................................10eeII2.2.2SiC/Al复合材料的性能特点......................................102.2.3试验刀具材料...................................................122.2.4试验刀具几何参数...............................................122.2.5试验切削用量的选择.............................................132.2.6切削液的选用...................................................132.2.7加工表面质量...................................................132.3SiC颗粒增强铝基复合材料的高速铣削试验.............................142.3.1试验条件与方法.................................................142.3.2试验结果及分析.................................................152.4铝基复合材料的钻削及攻丝加工试验..................................182.4.1试验材料.......................................................182.4.2切削试验及结果.................................................182.5切削铝基复合材料时的切屑变形及影响因素研究........................212.5.1车削试验.......................................................222.5.2试验分析与讨论.................................................222.5.3切屑变形研究...................................................242.5.4试验结论.......................................................252.6切削铝基复合材料时的刀具磨损及影响因素............................252.6.1试验部分.......................................................262.6.2分析与讨论.....................................................262.6.3切削用量对刀具磨损的影响.......................................272.6.4增强相体积分数及尺寸对刀具磨损的影响...........................282.6.5刀具材料的选用原则.............................................282.6.6试验结论.......................................................292.7复合材料切削刀具..................................................292.7.1刀具在切削加工中的重要性.......................................292.7.2切削技术及刀具的发展现状.......................................302.7.3切削刀具介绍...................................................312.7.4刀具经济性分析.................................................352.7.5刀具技术的发展趋势....................
