高速走丝气中电火花线切割精加工编程设计-毕业设计.doc

高速走丝气中电火花线切割精加工编程设计摘要最近几年来，随着模具的飞速发展，对模具加工表面质量要求不断提高，电火花线切割表面加工技术因此备受关注。这就要求电火花线切割要提高加工面的机械性能，降低表面粗糙度，从而达到提高模具使用寿命的目的。本文介绍电火花线切割加工的加工原理以及工作介质的应用。对传统电火花线切割加工基本原理和基本规律进行了探索和介绍。叙述了电火花线切割新方法的发展，它在合适条件下加工可提高加工精度。在高速走丝电火花线切割中由于加工反作用力是微小的，线电极振动也小。另外，因在一定条件下放电间隙也可以比传统电火花线切割窄，所以试件腐蚀也可以较小。高精度的精加工在高速走丝电火花线切割中可以实现。本文介绍了电火花线切割加工过程中发生的现象和相关的解释并结合MastercamX2软件对线切割实例进行编程设计。关键词电火花线切割；精加工；MastercamX2软件ProgrammingdesignofMechanismofHigh-SpeedWireElectricalDischargeFinishingAbstractInrecentyears,withtherapiddevelopmentofthemold,theWEDMsurfaceprocessingtechnologycausesomuchattentionbecauseofthemoldsurfacequalityrequirescontinuousimprovement.ThisrequiresimprovingmechanicalpropertiesofWEDMmachiningsurface,andreducingthesurfaceroughness,soastoachievethepurposeofimprovingthemoldlife.ThisarticledescribestheapplicationoftheWEDMprocessingprincipleandmedia.ExploresandintroducestraditionalEDMwirecuttingbasicprinciplesandlaws.DescribesthedevelopmentoftheWEDMnewmethod,itcanimprovetheprecisionundertheproperenvironment.SincetheprocessingreactionforceissmallintheWireElectricalDischargeFinishing,wireelectrodevibration.Inaddition,thedischargegapundercertainconditionsisnarrowerthantraditionalEDMwirecutting,sothespecimencorrosioncanalsobesmaller.High-precisionfinishingcanbeachievedinthehigh-speedWEDM.ThisarticledescribesWEDMphenomenonoccurredintheprocessingandinterpretationofwirecutinstanceofprogrammingdesigncombinedwithMastercamX2software.KeyWords：WEDM;finishing;MastercamX2software目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc326817103"摘要HYPERLINK\l"_Toc326817104"AbstractHYPERLINK\l"_Toc326817106"第一章绪论PAGEREF_Toc326817106\h-1-HYPERLINK\l"_Toc326817107"1.1电火花加工来源和电火花线切割综述PAGEREF_Toc326817107\h-1-HYPERLINK\l"_Toc326817108"1.2本题的背景PAGEREF_Toc326817108\h-1-HYPERLINK\l"_Toc326817109"1.3课题探讨内容PAGEREF_Toc326817109\h-1-HYPERLINK\l"_Toc326817110"第二章电火花加工基本原理PAGEREF_Toc326817110\h-3-HYPERLINK\l"_Toc326817111"2.1气体的放电特性PAGEREF_Toc326817111\h-3-HYPERLINK\l"_Toc326817112"2.2电火花加工的机理
