Striation Formation and Surface Finish in Laser Cutting of Mild
The mechanisms of melt ejection and striation formation in laser cutting of mild steel are discussed. It is argued that the melt ejection from the cutting front is not a steady state process, but rather shows a cyclic phenomenon. The striation are strongly affected by the unstable characteristic of the thin liquid film on the cutting front during the melt ejection, together with the oxidation a...

متن کاملExperimental Study of the Effect of Laser-Cutting Process Parameters on Heat Distribution and Cutting Edge Quality of Steel Sheets
This study aimed to evaluate Laser-cutting process of Mild Steel St37 sheets with two different thicknesses. In order to evaluate the quality of cutting edge and the depth of the area affected by the heat, several tests were conducted to determine the effect of parameters such as Laser power, Laser beam movement speed and pressure of axillary gas on the quality of cutting edge and the depth of ...
متن کاملStriation Mechanism in Laser Cutting – the Review
High-power laser cutting is extensively used in many industrial applications.The quality of a laser-made cut is of the utmost importance in laser processing. Any improvements in this area would be of considerable significance, in that it would lead to an elimination of post-machining operations. Although there have been numerous techniques developed over the years, currently there are few appro...
