本科毕业论文（设计）论文题目：基于SolidWorks的球头立铣刀参数化设计摘要本课题针对数控刀具的设计与制造现状进行研究分析，以SolidWorks2011为CAD开发平台，利用SolidWorks提供的API技术，结合VisualBasic技术,对SolidWorks进行二次开发,探索能够满足现代企业需求的“直柄立铣刀的三维参数化设计系统”的开发途径。本文主要以四刃球头立铣刀为例进行研究。本文从球头立铣刀的几何模型着手，在国内外关于球头立铣刀的设计、分析等方面研究的基础上，通过对传统等螺旋角刃口曲线的模型进行分析，建立了球头立铣刀柱面、球面上等导程螺旋线的数学模型。并联系加工过程等计算出球头立铣刀刃部及球头部分前刀面成形曲线的数学模型。本论文应用SolidWorksAPI技术和VB技术对SolidWorks进行二次开发，研究了基于SolidWorks的刀具三维参数化设计系统的开发思路和开发规范，通过调用SolidWorks内部的API函数对刀具参数化模型进行驱动，达到通过改变参数可以得到一系列不同尺寸的铣刀模型，使铣刀的设计变得方便、快捷。关键词：球头立铣刀，SolidWorks，数学模型，参数化，VBTechnologyofParametricDesignSystemforBallendMillBasedonSolidWorksAbstract3DParameterizedDesignSystemforHelix—BladedMillingCutterBaseonSolidWorks2011platformwasdevelopedtosatisfytherequirementfordesignandmanufacturingofnumericalcontrolcutterinmachiningshop．Thedevelopmenttools，VisualBasicwereappliedinthedevelopmentprocess,ThisdesignsystemprovidesaneffectiveprogramplatformtodesignFourbladeHelicalball-endcutter.InthisPaper,Basedonthegeometricmodelanddiscretizationofthemillingcuttingedge,ainternalanalyseandresearchaboutdesignandanalysisoftheball-endcutterisreviewed.Bythetraditionalanalysisoftheequalhelixangleedgecurvemodel，amathematicalmodeloftheequalSpiralleadisestablishedonthecylinderandsphereoftheball-endcutter.WithPracticeandProcesstocalculatetheball-endcutterknifegrooveback,Andcontacttheprocessingandcalculationofaball-millingbladeMinistryandtheballheadpartoftherakefaceformingthecurveofthemathematicalmodel.SolidWorksAPItechnologyandVBtoolwereemployedinthedevelopmentprocess．TheaimofdevelopmentSolidWorksistoimplement3-dimensionalParameterizeddesignofhelix—bladedmillingcutter．ThespecialmodulewasembeddedtheCADplatformSolidWorks,Achievebychangingtheparametercanbeaseriesofdifferentsizecuttermodel,thedesignofthecutterbecomesconvenient,fast.Keywords：Ballendmill，SolidWorks，Mathematicalmodel，Parametric，VB目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc325123906"第一章绪论PAGEREF_Toc325123906\h1HYPERLINK\l"_Toc325123907"1.1引言PAGE
