某辐射组件加工工艺研究

Research on Machining Process of Radiation Component

辐射组件是相控阵雷达天线的关键组件,具有内部结构复杂、尺寸小、尺寸精度要求高和表面粗糙度要求高等特点,采用常规机械加工的整体加工思路存在很大难度。针对某辐射组件的结构特点,就其机械加工工艺进行了多方面的分析,最终提出了先结构拆分再拼焊的加工方法,并加工出了合格的辐射组件,充分证明了该工艺方法可行、高效。同时成功地用金属3D打印技术成形出了该组件,为此类零件的加工提供了新思路。

The radiation component was a pivotal and important part of radar, which had complicated internal structure, small size, high dimensional precision and high surface smoothness. It was very difficult to machine the radiation component in its entirety. The paper provided the processing method of structure splitting first and butt welding second. By practice validated, the results indicated that the machining process was effective in the manufacture of radiation component. This paper also successfully manufactured the radiation component by using 3D mimeograph technology.
