Polycrystalline Diamond (PCD) materials are now widely used in machining various advanced materials in many fields due to their excellent performances such as high hardness, high wear resistance and high erosion resistance. However, the shaping of the PCD materials is challenging due to their inherent properties of high strength and high toughness. The main techniques generally used in PCD machining are mechanical lapping and electrical discharge grinding (EDG). The former is a conventional, slow and costly machining method. The latter offers high productivity and good flatness-controlling. In this paper,the influence of the main parameters of electrical discharge grinding such as workpiece polarity, pulse-on time, pulse-off time, open discharge voltage and peak current on the material removal rate of PCD are investigated. An artificial neural networks (ANN) is developed to describe the relationship between the EDG parameters and the performance characteristics. After training and testing, the maximal predicting error of the ANN model for the unknown technological condition is 14.29%, which can meet the requirment of practical application.
