Numerical simulation of drilling for carbon fiber composite materials

In order to investigate the peripheral milling process of the carbon fiber composite materials, three-dimensional finite element model of carbon fiber composite material for peripheral milling has been established. The key technologies of cutting layer simplification and material removing for the modeling are also investigated. The milling force to the finite element model is applied to studying the peripheral milling process of milling force to the carbon fiber composite materials . By means of numerical simulation, we obtain the stress distribution of carbon fiber composite materials during milling process. The study can provide theory reference for the optimization of cutting parameters and tool geometry.
