Summary:In industries many problems encountered in machining of micro holes. To overcome this, non-traditional machining processes are often used. The study is to optimization the significant machining parameter that influences the EWR in machining of micro holes using a die sinker EDM with Copper electrode of diameter 300 µm. The experiment studies were conducted by varying the current, pulse-on time and pulse-off time, as the process parameters for Taguchi experiment design were used and to ensure the required dimensional accuracy and geometry measures for electrode tool wear rate from the combinations parameters.
