Effect of composite material electrode on common die steel in EDM. Investigating the effect of composite material electrode on common die steel material in EDM

      Аннотация: The behavior of three types of tool electrodes while machining EN-31 Die steel through Electrical Discharge Machining has been investigated. The comparison was made between tools made of purely copper, copper tungsten and conventional copper tool available in the market. There are three main factors i.e. material removal rate, tool wear rate and micro hardness, based on which the comparison between the electrodes has been made. It was observed that by using composite material tool electrode significantly increases the material removal rate and decreases the tool wear to some extent so that the tool can be used for larger time on the work piece. Also by comparing the results of micro hardness, it has been seen that there can be significant increase in the surface finish of the workpiece.
