Paper Title:
Calculating the Overcut in Electro-Discharge Machining
  Abstract

The dimensional accuracy of electro-discharge machining (EDM) is greatly influenced by the overcut resulting from discharge gap and electrode wear. In order to achieve fine accuracy, it is necessary to estimate the overcut according to an empirical formula. In this paper, experiments in electro-discharge machining were carried out. The effects of parameters on the overcut, such as peak current, pulse duration, were analyzed. Then an empirical formula for the overcut in EDM was established based on the experimental results using the least square method. Finally, reasonable agreement between calculated results and the further experimental results was obtained.
