摘 要转向架是高速动车组的核心组成部分，其制造技术是确保动车组能够实现安全、平稳、舒适、快捷运行的关键性技术之一。转向架构架是转向架的基体，其制造精度直接影响着转向架的装配精度、安全性能，进而影响到动车组的运行品质与安全性。本论文主要介绍了动车转向架构架横梁零件的数控加工工艺分析与设计。通过对零件图，毛坯件，以与其结构工艺性的分析，从定位基准入手，确定各个表面的加工方法，划分加工阶段，合理安排加工顺序，选择机床设备，确定切削用量得到最终的工艺规程。一个优化的工艺设计，为零件加工的可行性和经济性提供理论依据，从而可以减少零件的加工时间，提高生产率，降低生产成本。关键字：转向架 数控加工 工艺 铣削 切削用量 AbstractBogie is a high-speed EMU core component of its manufacturing technology is to ensure that the DMUs to achieve safe, stable, comfortable, fast and run one of the key technologies. Bogie bogie frame is the matrix, and its direct impact on manufacturing precision bogie assembly accuracy, security, performance, thereby affecting the operation of EMU quality and safety. This paper introduces the vehicle bogie frame beams moving parts CNC machining process analysis and design. Map of parts, pieces of rough, and its structure analysis process, starting from the base position to identify the various surface processing methods, dividing the processing stage, reasonable arrangements for processing the order, select the machine tool equipment, to determine the final cutting process has been a point of order. An optimized process design for the feasibility of machining and economy and provide a theoretical basis, which can reduce machining time and improve productivity, reduce production costs.Keywords: BogieCNC MachiningProcess DesignMillingCutting毕业设计（论文）原创性声明和使用授权说明原创性声明本人重承诺：所呈交的毕业设计（论文），是我个人在指导老师的指导下进行的讨论工作与取得的成果。尽我所知，除文中特别加以标...
