چکیده
Planetary or Orbital tool actuation is one of the process improvement techniques used in Electro Discharge Machining (EDM) process which has multi facetted advantages. In present work, an attempt has been made to study the effect of various process parameters during planetary EDM of Ti-6Al-4V; a material which is difficult and expensive to machine by conventional methods. Parameters viz. Pulse ON time, Polarity of the tool electrode, Duty factor, Gap voltage and Pulse OFF time have been considered to study the process in terms of tool wear rate, wear ratio and surface roughness. Results suggest that Pulse ON time and Polarity of the tool electrode have significant effect on the responses. Comparative study between Planetary and Die sinking strategies suggest that planetary tool actuation in EDM have the potential to machine Titanium alloys more efficiently than conventional die sinking EDM.
