Diode laser assisted oxygen cutting of thick mild steel with off-axis beam delivery

I Sakaev et al.

Summary: The study introduces a strategy to reduce excessive melting at the top edge of the cut in laser assisted oxygen cutting of mild carbon steel, demonstrating high-quality cuts in 20 mm thick workpieces and lower quality separation in up to 40 mm steel thickness. The experimental results highlight the potential of high-power diode sources in LASOX cutting and the capability of compact and lightweight diode-based systems in cutting thick sections of mild steel.

Image-based modelling and visualisation of the relationship between laser-cut edge and process parameters

Leonie Tatzel et al.

Summary: This article introduces a new method of evaluating the laser cutting process by deducing process parameters directly from the laser cut edge using a convolutional neural network. The CNN performs well in estimating process parameters, with better performance on RGB images. The proposed method has the potential to monitor the condition of a laser cutting machine and quickly identify defective machine components.

Influence of process parameters on laser beam machining of leather for oil hydraulic system application

T. Geethapriyan et al.

Summary: Laser Beam Machining (LBM) is a unconventional process where the thermal energy of a laser beam is utilized to remove material, best suited for tough to cut materials like leather. When machining leather with LBM, the transverse speed is the most influential parameter, affecting the heat transfer time available for spreading.
