Paper Abstract

In this paper, we not only present a new method to model the drilling hole profiles but also explain why hole drilling will stop under certain circumstances in the low fluence regime for polymers and fiber reinforced composites. The model explains tapered wall formation and stabilized drilling, form which, high efficient laser drilling and cutting can be predicted in low fluence regimes. This new model is suitable for most well defined beams and materials such as polymers, fiber CDC, glass fiber composites and some ceramics, however, in this paper, the model does not address the case of beam intensity changing along the propagation direction.
