It is important to some of the development of industry that plays a more and more important role. With the development of science and technology, numerical control technology is in the development of updates. Now, numerical control technology are called computer numerical control technology. The application of CAD/CAM is a practical technique, like UG, PRO/E, Master CAM, CAXA manufacturing engineers, etc.Numerical control technology is highly technical work, especially in the mold domain. Practitioners requires high machining technology knowledge, CNC programming knowledge and skills.This text based on the analysis of nc craft and machining, comprehensive knowledge of professional knowledge, comprehensive consideration the influence factors of milling process, design the craft and editing program, complete requirements Follow the plastic mold industry fast development, mobile phone shell, audio, mobile power, U disk, display these electronic products need to use much of the plastic mold design and production can be carried out in the country. In the aspect of precision plastic parts, precision has reached IT6-IT7 level, the general level of roughness can reach Ra0.01-0.025 m, the life of injection mold are also can be up to one million times. In the process of mould design and manufacturing, CAD and CAM techniques are often applied, in addition, hot runner injection technology is used more widely.Keywords: mobile phone shell; numerical control nc; plastic mold design; machining simulation; UG; CAD/CAM TechnologyIII目目 录录诚信声明诚信声明.I摘要摘要.IIAbstract.III第一章第一章 绪论绪论.11.1 研究的背景.1 1.2 研究的意义.2 1.3 论文结构.2第二章第二章 零件设计及零件设计及 MasterCAM 参数设置参数设置.32.1 零件数控加工分析.3 2.1.1 零件分析.3 2.1.2 工艺分析.3 2.1.3 工序安排.3 2.2 心形凹模加工工序表.4 2.2.1 加工参数设置.4 2.2.2 平面加工.5 2.2.3 凹槽粗加工.8 2.2.4 凹槽侧壁精加工.12 2.2.5 生成的部分 NC 代码（详细代码请见附录 A）.14第三章第三章 机床的数控仿真机床的数控仿真.
