Suppressing the burr of high aspect ratio structure by optimizing the cutting parameters in the micro-milling process
TL;DR: Numerical simulations through the finite element method (FEM) and experiments are carried out to optimize cutting parameters of the specimen made of Cr12MoV alloy and an improved constitutive model is proposed by considering the size effect of the micro-milling, and it is concluded that the cutting force error is 4.6% through the comparison of experiment and FEM, which proves the convergence of the improved constitutionutive model.
