The effects of the hybrid process parameters on machining characteristics and surface modifications were comprehensively investigated to confirm the benefits of this hybrid process. The appropriate abrasives delivered by high speed gas medium were incorporated with an EDM in gas system to construct the hybrid process of AJM and EDM, and then the high speed abrasives could impinge on the machined surface to remove the recast layer caused by EDM process to increase the efficiency of material removal and reduce the surface roughness. In addition, the added abrasives could regard as the agents of surface modifications. In this study, the benefits of the hybrid process were determined as the machining performance of hybrid process was compared with that of the EDM in gas system. The main process parameters were varied to explore their effects on material removal rate (MRR), electrode wear rate (EWR), surface roughness (SR). The experiments were conducted based on Taguchi method. The experimental observed values were transferred to signal-to-noise (S/N) ratios, and then the significant machining parameters affecting obviously the machining performance were determined by analysis of variance (ANOVA). The optimal combination levels of machining parameters for each machining characteristic were obtained by the S/N ratio analysis according to Taguchi methodology. Moreover, the effects of surface modifications with relation to the machining parameters were also determined by the developed hybrid process. The experimental results show that the significant machining parameters affecting the MRR were machining polarity, peak current, and pulse duration; peak current was the significant parameter with relation to the EWR, and the peak current, pulse duration, and gas pressure were the significant in regard to the SR. In addition, The silicon content increased with increase in gas pressure, pulse duration, and peak current, as well the silicon content attained the value of 8.2 wt.% in the hybrid process with respect to surface modification. The developed hybrid process of AJM and EDM could enhance the machining efficiency and improve the surface modification. Consequently, the developed hybrid process could fit the requirements of modern manufacturing applications.This study developed a hybrid process of abrasive jet machining (AJM) and electrical discharge machining (EDM).
