Abstract—Electro Discharge Machining (EDM) is one of the most widely accepted advanced machining process to machine hard to machine electrically conductive materials. However, the inferior physical properties of the workpiece tend to make process unstable resulting into heavy loss of material from the tool electrode thereby leading in to generation of inaccurate features. In present work, an attempt has been made to study the effect of various process parameters viz. pulse ON time, duty factor, gap voltage and polarity of the tool electrode on end wear of the tool electrode and wear ratio during planetary EDM of Ti-6Al-4V. One factor at a time methodology has been employed to study the parameter effects. Results suggest that distortion on the tool electrode during EDM of Ti-6Al-4V is highly influenced by the pulse ON time level as well as polarity of the tool electrode employed. Further, it has also been understood that lower levels of duty factor and higher levels of gap voltage are preferable for efficient machining of titanium alloys.
