| Abstract: | A thermal model of micro-EDM deposition machining in gas was built, through se.lecting proper heat-source model, thermal boundary condition and diameter of discharge channel etc.. The thermal field of tool electrode and work piece was analyzed under single pulse and the processing parameters were predicted. The applicability of predicting processing parameters with this method was verified through experiment. |
