摘 要

随着现代生活节奏的加快，科技进步日新月异，激烈的竞争要求企业更快地将产品推向市场。CAM/CAD/CAE技术是提升产品性能、加快产品研发过程、提高效益的有效手段。UG NX4.0，是美国德克萨斯州普莱诺公司于2005年9月推出的产品全生命周期管理（PLM）软件。该软件的功能覆盖了整个产品的开发过程，即覆盖了从概念设计、功能工程、工程分析、加工制造到产品发布的全过程，在航空、汽车、机械、电器电子等各工业领域的应用非常广泛。

通过对UG三维造型模块的初步了解，和进一步的学习与应用，初步掌握了其三维造型的方法与应用，对其绘制图形方面起了良好的作用。

通过对UG三维造型的认知与了解，可以运用UG的绘图优越条件，对给定草图进行三维造型与设计，应用更为方便。

通过对UG的掌握，利用UG三维造型设计，对双向偏心夹具的部件进行绘制与编辑，便于熟练掌握UG三维造型设计的应用与认知。
