Abstract

Due to the continuous enhancements not only of aero engines, novel materials with higher hardness and high-temperature strength are nowadays often applied. The specific material properties limit the economic machining by conventional manufacturing processes while wire electrical discharge machining (EDM) ensures it. In addition, wire EDM is increasingly used to manufacture complex shapes e.g. rotationally symmetric components. For this purpose, multi axes machining is necessary to automate the manufacture. Due to the changed electrical contacting and flushing conditions by using such additional axes, an adaption of the technology is necessary. The development or adaption of a wire EDM technology are a big effort and time consuming. To simplify the adjustment of wire EDM technologies when using an additional axis, the influence of selected process parameters on the process performance is analyzed. The results of the investigations are supposed to serve as a reference for technology adaptions.
