Abstract

This paper presents a physical model characterizing the geometry of gas-assisted laser cutting of the AlSi-alloy/SiCp composite. In the model, a lot of relevant parameters that describe the inhomogeneous optical and thermophysical properties of AlSi-alloy/SiC_p have been used. Numerical evaluations of this model give some explanations of "double slope" formation mechanism during laser cutting of the AlSi-alloy/SiC_p. The theoretical results are compared with experimental data. It is found that increasing laser beam scanning speed increases the slope of cutting front.
