In the current scenario, the applications of natural fibers are increasing enormously due to their biodegradability, low-density and better mechanical properties. This research explains the machining nature of pineapple (P) and flax (F) fibers by the incorporation of cellulose micro filler (CMF). These epoxy-based composites were manufactured using compression moulding. In the machining process using abrasive water jet machining (AWJM), lower kerf angle of 1.31° and surface roughness of 5.1 µm were observed in 30% PF/2% cellulose micro filler hybrid epoxy combination. Agglomeration at higher filler incorporation causes decrease in machinability of hybrid 30% PF. Pineapple and flax hybrid fibers with 30 and 35 wt % showed better machinability at 2 and 3% cellulose micro filler addition. Scanning electron microscopy analysis after machining process showed reduction in flush off and pullouts of fiber by improved compaction with the epoxy matrix due to filler addition.
