Micro-EDM drilling Presented by: Mr. Mathew J Joseph , AP, ME Dept . Audience: Staff members, Department of Mechanical Engineering. Mr. Mathew J Joseph took a session on “ Micro EDM drilling ” based on his paper presented at the International Conference on Precision, Meso, Micro and Nano Engineering at NIT Calicut . The contents of the discussion were the following: • Introduction to the concept of Micro-EDM in comparison with the conventional EDM processes and their advantages . • Tubular electrodes used in micro-EDM drilling • The main work discussed included the optimization of the process parameters in micro-EDM drilling for improving MRR (material removal rate) and minimizing Over- cut. • The entire experimental procedure and the obtained results were discussed and the analysis of the effect of the process parameters (voltage, capacitance, electrode feed rate and electrode rotation speed) was done. The session was follo
