Finite element modelling and experimental investigation in the precision micromachining of magnesium-based nano SiO ₂ nanocomposites

Metal matrix composites, particularly those reinforced with nanoparticles, are garnering increasing interest across academic and industrial sectors. For their potential to be fully realized in upcoming applications, an in-depth understanding of their machinability is crucial. This study introduces a pioneering method for constructing simulation models, culminating in the development of a chip simulation model that incorporates real nanoscale dimensions, apt for nanoparticles within composite materials. Subsequently, an experimental methodology is applied to ascertain the validity of the cutting simulation model concerning stress distribution, chip formation, and surface morphology. The findings affirm the simulation model's efficacy, providing nuanced insights into the cutting mechanisms of SiO 2 nanoparticle-reinforced metal matrix composites through the lens of finite element analysis. The novelty of this research fills the gap that the random disturb of nano-scale particles that same as realistic content of nanocomposites via Finite Element Analysis (FEA) process.
