Journal ArticleDOI
Time scale effects in laser material removal: a review
TL;DR: In this article, a Q-switched solid state laser with a pulse width on the order of nanoseconds is used for laser material removal, where the primary material removal mechanism is ablation, but substantial melting is still present if a metallic material is concerned.
Journal ArticleDOI
Experimental investigation of hydrodynamics of melt layer during laser cutting of steel
TL;DR: In this paper, the authors observed the hydrodynamics of melt layer on a kerf front in the case of laser cutting of steel with an inert gas, and they showed that the melt flow on the kerf front exhibits strong instability, depending on cutting velocity.
Journal ArticleDOI
Numerical simulation of oxidation effects in the laser cutting process
TL;DR: In this paper, a numerical model for the process of oxygen assisted laser cutting of mild steel was developed, where coupled oxygen concentration and energy balance equations were solved by a control-volume-based computational scheme, while the velocity field was obtained by analytical boundary theory.
Journal ArticleDOI
Laser Cutting: A Review on the Influence of Assist Gas
Antonio Riveiro,Félix Quintero,Mohamed Boutinguiza,Jesús del Val,Rafael Comesaña,Fernando Lusquiños,Juan Pou +6 more
TL;DR: In this work, the aerodynamic interactions between the assist gas and the workpiece are reviewed and an insight into those phenomena that hinder the cutting quality and performance is provided.
Journal ArticleDOI
Study of melt flow dynamics and influence on quality for CO2 laser fusion cutting
TL;DR: In this article, the results of the study of the melt flow dynamics during laser cutting of glass were analyzed using a high-speed video camera to study the process and a phenomenon concerning the plasma plume formed during the process was observed, which has not been previously reported in the literature.
