The Effects of Nanoparticle Reinforcement on the Micromilling Process of A356/Al2O3 Nanocomposites

Improving scientific knowledge around the manufacturing of nanocomposites is key since their performance spreads across many applications, including those in meso/micro products. Powder metallurgy a reliable process for producing these materials, but usually, machining postprocessing required to achieve tight tolerances and quality requirements. When processing cutting force evolution determines ability control microcutting operation toward successful surface part generation. This paper investigates generation during micromilling A356/Al2O3 aluminum produced via powder metallurgy. A set experiments were carried out under various parameters on with different nano-Al2O3 reinforcements (0–12.5 vol.%). The material’s ductility, internal porosity, lack interparticle bonding cause be irregular when nanoparticle absent or small. Reinforcement ratios higher than 2.5 vol.% strongly affect by regularizing milling lead proportionally increasing average magnitudes. Hardening due nano-reinforcement positively affects mechanisms reducing plowing tendency process, resulting better quality. Therefore, threshold particles’ volumetric loadings enables an optimal design composite materials support micromachinability.
