第 1 课课程概述本课程主要讲述怎样用 UG 加工模块去建立两维半和三维刀具路径。概述本课程重点是学习怎样有效组织 UG 加工应用，让 UG 加工的新手学习怎样使用 UG 的各项功能。本课程包含许多概念，同时提出许多建议，这些建议对充分发挥 UG 加工模块的功能是有帮肋的。学习本课程的学生应该对 UG Modeling、 UG Assembly 有一定的了解。如果学生以前有 NC 加工方面的经验，将会对学习本课程有帮助。练习与练习文件教材中附带了一些练习，练习起到巩固课程中所学内容的作用。练习中要用到的 UG part 文件也与教材放在一起。每一节的文件放在不同目录中，装配文件放在下一级子目录中。系统权限所有 UG Part 文件权限设定为只读，学生不可以修改它。但是的可以用 File—Save as--功能把该文件保存在你自己的个人目录里。术语下面是 UG 加工中常用到的一些术语。样板文件（Template File）----样板文件是包含了诸如工具( Tools )，方法( Methods )和 Operation 等信息的文件。这些信息能被其它的 Part 文件取用。 Operation ----UG 中的 Operation 包含了产生刀具路径所需的全部信息。刀具路径（Tool Path）---- 刀具路径包含了刀具位置，进给速度，转速，显示信息和后处理命令等信息。后处理 ( Post Process )----这是一个转换过程。它把 UG 输出的刀具路径文件转换成机床可用的标准格式。 MCS----加工座标系。刀具的位置是根据加工座标系来输出的。步距 ( Step Over ) ----刀具相邻路径之间的路离。材料方向 ( Material Side )----材料保留的方向边界 ( Boundary ) ----限制刀具路径的边界。零件几何体 ( Part Geometry )----加工完成后要保留下来的材料。毛坯几何体 ( Blank Geometry )----加工中要切削的材料。检查几何体 ( Check Geometry )----加工中刀具要避开的材料或特征。 1
