摘　　要：微模具型腔的高效、高精密加工,一直是制约微模具制造技术发展的瓶颈问题。以微细电火花加工用的圆柱阵列结构微细电极为对象,研究了应用高速铣削加工技术,实现微细电极的高效、高精密加工方法。通过优化分析微细电极结构和高速铣削加工参数及刀具路径,获得了尺寸和形状精度及表面质量均满足要求的阵列结构微细电极,并以制得的微细电极进行微模具型腔的微细电火花加工。结果表明,采用高速铣削方法加工的微细电极,较好地满足了微模具型腔的加工质量要求。High efficiency and precision of machining micro-cavity mold has been restricting the development of micro-mold manufacturing technology. In order to study the application of high-speed milling technology to achieve high efficiency and precision micro-electrode processing method, the cylindrical micro-electrode with array structure used in micro-EDM was adopted for this object. By analyzing and optimizing the micro-electrode structure, high-speed milling parameters and tool path, a satisfying shape and size accuracy and surface quality micro-electrode which subsequently used in micro- EDM experiment of micro-cavity mold was obtained. The results show that high-speed milling method for processing micro-electrode satisfies the micro-cavity mold quality requirement.
