MACHINING PARAMETERS OPTIMIZATION IN TURNING OF ALUMINUM NITRIDE (ALN) PARTICULATE REINFORCED ALUMINIUM MATRIX COMPOSITES
Keywords:Alunimium Nitride, Composites, Turning, Cutting force, Flank wear, Surface roughness, Optimization
Aluminum composites have gained extensive notice in the material world and replaced the usage of ferrous materials. It was widely accepted in aerospace, space craft and army and navy applications as it is having moderate strength and fewer density. Preferring the operating parameters has an imperative part in producing the components with close tolerance and superior surface finish at the economic rate of machining. Identifying the appropriate machining parameters for a particular material is still the subject of the scientific group of people. The major contribution of the work is to optimize the machine operating parameters to diminish cutting force, flank wear and surface roughness in turning of Al-AlN composites. L27 layout was followed for experimental trails and Taguchi method was employed for optimization. Experimental result demonstrates that the feed rate has strongest effect on cutting forces and surface roughness whereas reinforcement ratio has strongest effect on flank wear.
