| Popis: | 99 The goal of this study is to develop a hybrid process of abrasive jet machining (AJM) and electrical discharge machining (EDM). The effects of the hybrid process parameters on machining performance were comprehensively investigated to confirm the benefits of this hybrid process. The appropriate abrasives that delivered by high speed gas media 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 resulted from the EDM process to increase the efficiency of material removal. In this study, the benefits of the hybrid process were determined as compared the machining performance of hybrid process with that of the EDM in gas. The main process parameters such as peak current, pulse duration, gas pressure, gas media, abrasive type, and grain size were chosen to explore their effects on material removal rate, electrode were rate, surface roughness and surface integrity. |
