摘 要
CAD/CAM技术的迅猛发展以及软硬件水平的进一步完善，为制造业提供了强有力的技术支持，也为企业的产品设计、制造和生产水平的提升带来了质的飞跃，CAD/CAM技术已经成为现代企业信息化、集成化和网络化的必然选择。
而在现代工业生产中，大部分的产品都需要进行三维造型与实体加工仿真，本文以飞机控制系统安装底盘零件为例，应用CATIA软件，结合专业课程理论，进行三维造型与实体加工仿真。首先对电视盒的结构进行分析，构思实体造型思路，通过CATIA里面的建模模块，应用拉伸，旋转，布尔运算等特征功能对实体进行造型。通过对实体的造型，根据实体结构的分析确定了加工思路，通过CATIA的加工模块，应用设置刀具，选择毛坯，生成刀轨等特征功能对实体进行加工。对飞机控制系统安装底盘零件造型及实体加工仿真进行了深入的探究，详细介绍了三维造型的过程，对实体加工仿真同时也进行了详细的阐述，并且进行了VERICUT的验证仿真。
通过对飞机控制系统安装底盘零件造型及实体加工仿真，可以缩短产品开发周期，降低生产成本，提高产品质量和生产效率，激发我国制造业发展的新思路，促进我国制造业的发展。

ABSTRACT
The rapid development of CAD/CAM technology and the software and hardware level of further improved, provided strong technical support for the manufacturing industry, also for the enterprise product design, manufacturing and production level of ascension brings a qualitative leap, CAD/CAM technology has become the inevitable choice of modern enterprise information, integration and networking.
In modern industrial production, most of the products need to be 3D modeling and simulation entity processing, based on the aircraft system of control chassis parts as an example, the application of CATIA software, combining the theory of professional courses, 3D modeling and simulation entity processing. First carries on the analysis about the structure of the aircraft system of control chassis parts，thinking entity modelling idea, through the modeling module in CATIA, application of stretching, rotating, characteristic functions such as Boolean operation on entity model. Through to the entity modelling, according to the analysis to determine the Settings tool, select blank, characteristic functions such as tool path is generated processing simulation conducted in-depth exploration, 3D modelling process was introduced in detail, to the real machining simulation is also carried on the detailed elaboration, and has carried on the simulation validation of VERICUT.
Through to the aircraft system of control chassis parts 3D modelling and simulation entity processing, can shorten the product development cycle, reduce production cost, improve product quality and production efficiency, and stimulate new train of thought on the development of manufacturing industry in our country, promote the development of manufacturing industry in our country.
Key words: CATIA, 3D, machining simulation, validation of the simulation
