abstract

  • This work is focused on the study of orthogonal cutting of long fiber composites. A model based in finite element was developed. The mechanisms of chip formation of Glass and Carbon Fiber Reinforced
    Polymer (FRP) composites were analyzed. Significant differences were
    observed when comparing machining induced damage predicted with the
    model for both materials. While damage extended widely ahead the
    interface and beneath the tool tip in the case of GFRP, damage was
    located in a much smaller zone in the case CFRP. The fiber orientation
    influences both the mechanism of chip formation and the induced
    subsurface damage.
