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Visual Basic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 SolidWorks API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，VB Technology of Parametric Design System for Ball end Mill Based on SolidWorks Abstract 3D Parameterized Design System for Helix—Bladed Milling Cutter Base on SolidWorks2011 platform was developed to satisfy the requirement for design andmanufacturing of numerical control cutter in machining shop．The development tools，Visual Basic were applied in the development process,This designsystem provides an effective program platform to design Four blade Helical ball-end cutter. In this Paper, Based on the geometric model and discretization of the milling cutting edge, a internal analyse and research about design and analysis of the ball-end cutter is reviewed. By the traditional analysis of the equal helix angle edge curve model，a mathematical model of the equal Spiral lead is established on the cylinder and sphere of the ball-end cutter.With Practice and Process to calculate the ball- end cutter knife groove back, And contact the processing and calculation of a ball-milling blade Ministry and the ball head part of the rake face forming the curve of the mathematical model. SolidWorks API technology and VB tool were employed in the development process．The aim of development SolidWorks is to implement 3-dimensional Parameterized design of helix—bladed milling cutter．The special module was embedded the CAD platform SolidWorks,
