Abstract
The work presented in this paper is carried out to study the effect of the cryogenic treatment on the electrode material to improve the tool life. The experiments were performed in H13 material using untreated electrode and cryogenic treated electrode. The input process parameter studied for different level of interactions are discharge current, Voltage and pulse on time. L9 Taguchi method of optimization was used for this input parameters to see their effect on the electrode wear with different treatments to the tool. Discharge current is found to be the most contributing factor for electrode wear in both untreated and treated electrode. The experiments has established an improvement of 29.77% in the life of the tool.
