Surface finish is very much important in all the machining processes. Fillers were playing the important role in the surface quality during the machining process of hybrid composites. This work addresses the influence of different weight percentages (wt. %) of basalt and graphene filler on the Abrasive Water Jet Machining (AWJM) surface quality. Hybrid composites of Banana/ sisal were prepared with 3 wt. % and 6 wt. % of basalt and graphene filler and 3 wt. % of basalt and 1 wt. % of basalt and graphene hybrid fillers. The AWJM has been carried out and investigated the effect of fillers on surface quality. The enhanced results were obtained during the 6 wt. % of graphene filler addition with the banana /sisal hybrid composite. The predicted surface roughness of 2.42 mu m was obtained for the optimum machining parameters such as 250 MPa of P, 100 mm/min of v, 3 mm of d. The improvement in surface quality was noticed in the hybrid filler composite.
