The Influence of EDM Parameters in Finishing Stage on Surface Quality Using Artificial Neural Network

Author

Abstract

In this work, the influence of different EDM parameters (pulse current, pulse voltage, pulse on-time , pulse off-time) in finishing stage on  the surface roughness (Ra)  as a result of application copper electrode to a workpiece( cold work steel  DIN1.2379)  has been investigated. Design of the experiment was chosen as full factorial. Statistical analysis has been done and artificial neural network has been used to choose proper machining parameters and to reach certain surface roughness. The experiment results indicated a good performance of proposed method in optimization of such a complex and non-linear problems.
