摘要

在设计领域，复杂部件通常用于功能和人体工程学目的。这些零件表面曲率不规则，形状复杂，加工难度大。本文介绍了CAD/CAM在复杂机械零件“起落架连接件”的建模、工艺规划和制造中的应用。采用UniGraphics CAD/CAM系统对零件进行建模。制定了加工工艺方案，并进行了刀具轨迹仿真。然后生成数控代码，使用数控铣床进行加工。确定了零件的最佳建模方法和刀轨顺序。推荐的切割参数也被突出显示。

Modelling and machining of complex mechanical parts using CAD/CAM systems

In the design world, complex parts are commonly used for both functional and ergonomics purposes. These parts are difficult to machine due to its irregular surface curvatures and the complex features. This paper presents the application of CAD/CAM in modelling, process planning and fabrication of a complex mechanical part called "landing gear connector fitting". The part is modelled using UniGraphics CAD/CAM system. The process planning is developed and tool path simulation is carried out. NC codes are then generated for machining using CNC milling machine. The best modelling method and tool path sequence for the part are determined. The recommended cutting parameters are also highlighted.
