Description
Summary:Dry EDM is an environment-friendly modification of the oil based EDM process. In the current work, a unit has been developed to implement dry EDM process on existing oil based EDM machine. All experiments are performed on bright mild steel with the help of hollow copper electrode. Response variables analyzed are material removal rate, tool wear rate and surface roughness. Design of experiments is done using Taguchi method. All experiments are performed using process parameters such as current, pulse on time and oxygen gas pressure. The statistical analysis of results show that current and POT significantly influence MRR and TWR.
