Investigation of cutting force in end milling of Al/n-Tic/MoS2 sintered nano composite

In industries, metal matrix nano-composites have implied its position by the mechanical properties. But, studies have given importance to micro/macrosize particles. The main aim of the research analysis is to understand the influence of machining parameters for the cutting force (Fc) and surface roughness (Ra) in end milling of hybrid nanocomposites Al + 10 % n-Tic + 7,5 % MoS2. Powder metallurgy process is adopted to prepare nano-composite samples. Microstructural analysis of nano-composite material done by Field Emission Scanning Electron Microscope (FESEM) confirms the uniform distribution of the reinforced particle. Experimentation was conducted by Central Composite Design (CCD), and the evaluation of surface roughness and cutting force was carried out using Response Surface Methodology (RSM) and Genetic Algorithm (GA).
