摘要
The titanium (Ti) alloys are the notoriously "difficult-to-machine" aerospace materials. Compared with the traditional mechanical cutting methods which are costly because of high tooling costs, electrodischarge machining (EDM) is an effective machining method for the Ti alloys. The energy distribution during the EDM process of Ti alloys was rarely reported, though it is a very important factor that can affect the machining performance. In this work, the energy distribution during EDM of Ti-6Al-4V has been investigated by a novel method, at different EDM parameters including interelectrode distance, pulse duration, polarity, and electrode shape. The results of this work show that energy distribution characteristics are greatly affected by the power density applied on the electrodes and more energy is distributed into the anode than into the cathode, which are in good concurrence with the results obtained by other authors. The results of this work will be helpful for further improving the technological performance of this process.
