Abstract

With wide application of carbon fiber reinforced plastics (CFRP) in aeronautic and astronautic products, the machining of FRP, particularly by means of milling is gaining more and more attention. In order to analysis the milling mechanism and process, both macro-mechanical and micro-mechanical 3-D finite element (FE) models were developed in this paper for machining simulation of unidirectional CFRP. Three-dimensional Hashin criterion is used for material damage prediction. The milling force simulated by two models was analyzed. The delamination is also simulated based on cohesive element in micro-mechanical model. The simulation result shows that the milling force and the delamination increase with increasing feeding rate, and decrease with an increase of the cutting speed, as is consistent with experimental observations.
