Assist gas plays a central role in laser fusion cutting. In this work, the aerodynamic
interactions between the assist gas and the workpiece are reviewed. An insight into those …

Achieving precise kerf cut characteristics in laser beam cutting (LBC) is contingent upon the
meticulous modeling of the process. This research delves into a comprehensive …

Abstract The three-dimensional (3D) theory of laser cutting is presented. The cutting
efficiency determined by its ultimate parameters at different types of polarization is …

In a considerable proportion of the published work on the subject of laser–oxygen cutting of
mild steel, the details of the oxidation reaction are overlooked or confused. For example, it is …

To manufacture parts with nano-or micro-scale geometry using laser machining, it is
essential to have a thorough understanding of the material removal process in order to …

In a laser cutting process, understanding of the hydrodynamics of melt layer is significant,
because it is an important factor which controls the final quality. In this work, we observed …

Influence of processing parameters and optimal conditions for CO2 laser cutting of an
aluminium–copper alloy (2024-T3) have been determined. Results are evaluated in terms of …

In this paper the morphology of the laser cut front generated by fibre lasers was investigated
by observation of the 'frozen'cut front, additionally high speed imaging (HSI) was employed …

An analytical model is presented which incorporates the effects of using O2 as assist gas.
The contribution of the enthalpy of oxidation used in the model was determined …

Striation, ie periodic lines appearing on the cut surface, is one of the most important quality
factors in laser cutting. It affects the surface roughness, appearances and geometry …
