Many of the recent developments in the fields such as aerospace, automobile and nuclear engineering industries are partly due to the increasing usage of difficult-to-machining materials. The machining of these materials is very tedious and time consuming process. Non-conventional machining processes have been developed to overcome these difficulties. Electrical Discharge Machining otherwise known as thermal erosion process is one of the non-conventional machining processes. This book deals about the analysis of pulse generators on machinability in electrical discharge machining processes
