1、毕业综合实践说明书题目：零件在UG中的建模与加工所属系部：软件学院专业班级：12春机械1班学生姓名：曲永欣指导教师：刘国平2014年4月30日毕业综合实践任务书学生姓名：曲永欣专业班级：12春机械1班所属系部：软件学院题目：零件在UG中的建模与加工任务内容：1、确定工件各部件尺寸。2、在UG软件中进行三维实体建模。3、应用到特征操作中的，拉伸、旋转、样条曲线、倒角、等指令。4、在UG中用虚拟加工进行加工。设计技术参数或论文撰写要求：参考UG课程设计论文规范要求时间安排：1、2014.2.24-3.07：确定课程设计题目，确定尺寸与图片2、2014.3.10-

2、21：进行大体设计3、2014.3.24-4.07：进行精细设计4、2014.4.10-30：完成电子档设计并完成课程设计说明书参考资料：1、UG讲义2、上网查找摘要在UG中完成一个型腔工件的建模与加工，在工件的建模过程中充分的利用上派生直线；拉伸；曲面等一些GU的相关操作，把工件建模出来后进入下一步在GU中的模拟加工加工。在加工过程中创建各种刀具和各种加工方法，在查看加工过程中发现有打刀的情况，我们先的查看在那步发生的打刀，在它的上一步调整避让，调整完成后在生成刀路，查看铣削完成后刀的位置，这样就完成了整个工件的加工。关键词：曲面；求差；拉伸；目录摘要··

7、零件设计直接建立二维草图平面，在草图平面内选定区域进行作图操作。（如图示）在草图平面内用矩形操作画一个长120宽100的矩形图形。（如图示）48曲永欣零件建模加工点击完成草图后再点击图拉伸命令，设置拉伸高为23mm。（如图示）在拉伸完成的图形上表面建立二维草图平面。（如图示）48曲永欣零件建模加工在刚刚建立的草图平面中建立一对中心线，灾运用派生直线命令操作。（如图示）同样使用上一步的派生直线命令，派生出另外两条直线。（如图示）48曲永欣零件建模加工在运用曲线偏置，设置偏执距离3。（如图示）完成草图，再进行拉伸命令，拉伸高为5mm。（如图示）48曲永欣零件建模

8、加工在平面上做4个通孔，运用拉伸命令，设置拉伸距离为
