Summary:Laser cutting of composite materials requires improving physical models applied to laser cutting process. In setting of machining parameters knowledge of physical phenomena occurring in the material plays important role. Material penetration, cutting front stabilization origin and propagation of cutting material are stages in attaining laser cutting. It shows an association of processing parameters (power, cutting speed) with these stages. Laser beam intensity and interaction time between laser radiation and material are sizes that show the physical phenomena occurring in the material. The paper presents an application for cutting of composite materials. There was considered a similar theoretical treating of thermal fracturing of the material with phase transformation. Power and cutting speed are technological parameters set for laser cutting. The relationship between these parameters in the physical and technical conditions partial determined was studied.
