中文摘要:
      针对某型航空发动机燃油喷嘴结构尺寸微小、材料硬度较高、切削加工困难等问题,介绍了微细电解加工的原理和实验装置,制备了微细棒状工具电极和三角形钩状成形电极,利用分层电解铣削进行粗加工快速去除工件多余材料,再利用环形扫描电解铣削进行旋流室全锥面的精加工,实现了发动机喷嘴微小尺寸旋流室的微细电解加工成形,达到加工精度和表面质量要求。研究表明,微细电解铣削加工是加工金属材料微小结构的有效可行的方法。
英文摘要:
      Aimed at fuel injection nozzles of a type of aero engine are difficult to cut with traditional machining methods because of the following problems of micro sized and hard material, the principle and set up of electrochemical micromachining and device were introduced. A micro rod tool electrode and a triangle hooked electrode were made. Rough machining process with layered electrochemical milling was used to remove remained material of the part, and finish machining process with swirl scanning electrochemical milling was applied to machine the full surface of the swirl chamber. The micro sized swirl chamber with high precision and good surface roughness of an aero engine nozzle was achieved with electrochemical micromachining technology. Study results show that electrochemical milling micromachining is a feasible and effective method to machine micro structures of metal parts.
