基于UG软件的鼠标建模及加工
摘要
UG（Unigraphics NX）是Siemens PLM Software公司出品的一个产品工程解决方案，它为用户的产品设计及加工过程提供了数字化造型和验证手段。Unigraphics NX针对用户的虚拟产品设计和工艺设计的需求，提供了经过实践验证的解决方案。UG同时也是用户指南（user guide）和普遍语法（Universal Grammar）的缩写。
这是一个交互式CAD/CAM(计算机辅助设计与计算机辅助制造)系统，它功能强大，可以轻松实现各种复杂实体及造型的建构。它在诞生之初主要基于工作站，但随着PC硬件的发展和个人用户的迅速增长，在PC上的应用取得了迅猛的增长，已经成为模具行业三维设计的一个主流应用。
UG的开发始于1969年，它是基于C语言开发实现的。UG NX是一个在二维和三维空间无结构网格上使用自适应多重网格方法开发的一个灵活的数值求解偏微分方程的软件工具。
一个给定过程的有效模拟需要来自于应用领域(自然科学或工程)、数学(分析和数值数学)及计算机科学的知识。然而，所有这些技术在复杂应用中的使用并不是太容易。这是因为组合所有这些方法需要巨大的复杂性及交叉学科的知识。一些非常成功的解偏微分方程的技术，特别是自适应网格加密（adaptivemeshrefinement）和多重网格方法在过去的十年中已被数学家研究，同时随着计算机技术的巨大进展，特别是大型并行计算机的开发带来了许多新的可能。
现随着塑料工业在我国迅速发展，为了提高产品的精度，降低产品的报废率，提高生产效率，运用软件建模也越来越起到了不可忽视的作用。目前在我国的国情之下，基于UG的建模在不少公司中应用的越来越广泛。自从UG推出以来，在航空航天、汽车、通用机械、工业设备、医疗器械以及其他高科技应用领域的机械设计和模具设计、加工等领域得到了广泛的应用。本文就是基于UG对鼠标进行了建模和分析，主要工作包括以下几个方面：
(1) 本文根据实际生产情况和研究的需求，通过人体工学，不影响人们在使用鼠标时的舒适度的情况下，选择合适的尺寸。然后使用UG软件对进行鼠标建模。
(2) 通过UG软件对鼠标进行三维建好模后，进入加工环境。制定毛坯、创建程序、创建工序、创建刀具、创建几何体，修改好参数，然后对鼠标加工进行仿真，运用“后处理”将NC加工程序导出。

Modeling and Simulation of mouse Based on UG
Mechanical engineering and automation
Unigraphics (Siemens) is a product engineering solution produced by Siemens PLM Software. It provides the digital modeling and verification means for the product design and the process of the user. Unigraphics NX provides a proven solution for the user's needs for virtual product design and process design. UG is also an acronym for user guide and Universal Grammar.
This is an interactive CAD / CAM (computer aided Design and computer aided Manufacturing) system. It is powerful and can easily realize the construction of various complex entities and models. It was mainly based on the workstation at the beginning of its birth, but with the development of the hardware and the rapid growth of personal users, the application on the personal computer has been increasing rapidly, and has become a mainstream application of the 3D design of the,The development of the U
G started in 1969, and it was developed based on C language. The UG is a flexible software tool for numerical solution of partial differential equations in 2D and 3D unstructured grids using adaptive more than method.
The effective simulation of a given process requires knowledge of applications (natural science or engineering), mathematics (analytical and numerical mathematics), and computer science. However, the use of all these technologies in complex applications is not too easy. This is because the combination of all these methods requires a great deal of complexity and interdisciplinary knowledge. Some of the most successful techniques of partial differential equations, especially the adaptive grid encryption (adaptivemeshrefinement) and the more than method, have been studied by mathematicians in the past ten years. At the same time, with the great progress of computer technology, especially the development of large parallel computers, a lot of new possibilities have been brought.
Now，with the rapid development of plastic industry in China， in order to improve the accuracy of product，reduce the scrap rate of products and improve production efficiency，we use the software modeling ，increasingly， playing a role can not be ignored. At present，under the situation of our country，our modeling based on UG that has been used by a number of Companies more and more widely. In the field of the aerospace，automotive，general machinery，industrial equipment，medical equipment and other high-tech applications，processing and other fields has been widely used. This paper is carried out and based on UG modeling and analysis of the mouse. The main work of my research including the following aspects:
（1）In this paper，according to the actual sit uation of production and demand and the comfort of people using the mouse，Through the human body engineering，I choose the right size. And then I use the UG software on the mouse model.
（2）Based on the three-dimensional model mouse after UG software build，I will enter the processing environment to create blank，create procedure，create tool，create geometry and modify parameters. Then I'm going to mouse processing simulation.
