河南科技学院2009 届本科毕业设计设计题目：基于 UG 的齿轮虚拟加工及蜗轮蜗杆的造型研究学生姓名： 杨玉飞所在院系： 机 电 学 院所学专业： 机电技术教育导师姓名： 逄 明 华完成时间：2009 年 5 月 27 日2摘 要本文主要介绍了在UG下齿轮、蜗轮蜗杆的三维建模。通过表达式绘制出渐开线，经过 修剪绘制出齿廓截面，然后进行拉伸和特征 阵列建立起齿轮的模型。蜗轮蜗杆通过表达式绘制出螺旋线和渐开线，绘制出或修改成齿廓截面，然后进行扫掠、特征阵列、布尔求差得到三维模型。重点研究在UG下对圆柱直齿轮进行虚拟加工模拟。通过创建毛坯，创建程序节点，创建加工 节点，创建操作，参数设置这一系列过程最终生成刀轨，借助UG CAM 的后 处理功能，将刀轨转换为能被数控系统所能接受的数控程序。虚拟加工可以降低造型难度、提高设计效率， 直接降低齿轮的试切、调试费 用， 缩短试切周期。关键词 :UG;表达式;齿轮;渐开线;虚拟加工3The Virtual Manufacturing of Gears and The Modeling Study of Worm Based on UGAbstractIn this paper, the three-dimensional modeling of the gears and worm gear are mainly introduced in UG. Drawn through the expression involute, after pruning drawn cross-section tooth profile, and then proceed to stretch and features an array of models to build gear. Worm drawn through the expression and involute spiral lines, drawn or modified into a cross-section tooth profile, and then swept, the characteristics of the array, Boolean been poor for three-dimensional model. Focus on the UG on Spur Gear for virtual machining simulation. Through the creation of rough, create procedure node, create a processing node, the creation operation, parameter setting process of the end of this series of tool path generation, use the post-processing functions of UG CAM, will be converted to tool path CNC system acceptable to the NC program. The virtual manufacturing can reduce the difficulty of modeling to improve design efficiency, reduce gear direct shear test, commissioning costs, cut cycle to s
