Comparison of Soft Computing Techniques for Modelling of the EDM Performance Parameters

Abstract EN

Selection of appropriate operating conditions is an important attribute to pay attention for in electrical discharge machining (EDM) of steel parts.

The achievement of EDM process is affected by many input parameters; therefore, the computational relations between the output responses and controllable input parameters must be known.

However, the proper selection of these parameters is a complex task and it is generally made with the help of sophisticated numerical models.

This study investigates the capacity of Adaptive Nero-Fuzzy Inference System (ANFIS), genetic expression programming (GEP) and artificial neural networks (ANN) in the prediction of EDM performance parameters.

The datasets used in modelling study were taken from experimental study.

According to the results of estimating the parameters of all models in the comparison in terms of statistical performance is sufficient, but observed that ANFIS model is slightly better than the other models.
