摘　　要：高速动车组铝合金车体侧墙是关键大部件之一,介绍了雷尼绍测量技术与840D系统参数化编程技术应用,在侧墙门口加工过程中通过旋转坐标系及改进加工路线等措施有效解决了掉料打刀、工件过切等问题。通过工艺改进后显著提高了车体侧墙整体加工质量,具有重要的工程应用价值。Side wall are key parts of aluminum alloy car body on high-speed EMU. Renishaw measure technique and Siemens 840D program of preferences were introduced in this paper. Circum rotating reference frame and ameliorating machining course were used in machining doorway of side wall, which solved reamer breakage and overabundance cutting problems; machining quality was enhanced observably after technology improving.
