INVESTIGATION OF THE SURFACE QUALITY OF AA6082-ZrO2-Gr MMCs USING ABRASIVE WATERJET MACHINING

Aluminium metal matrix composites have wide applications in the aerospace and automotive industries due to their excellent physical properties like hardness, tensile strength, etc. The reinforcement of ZrO2 hard ceramic particles soft solid lubricant graphite on AA6082 produces a high-strength composite. This research aims fabricate AA6082-ZrO2-Gr MMCs with different compositions evaluate abrasive-waterjet-machining (AWJM) parameters machining fabricated composites, which eliminates thermal distortion damage work material. experiments were conducted by varying dominant process such as water pressure, traverse speed, abrasive flow rate mesh size. kerf taper angle was affected speed while surface roughness rate, size pressure. 120 provided best finish.
