Automation of lathe checks detection using deep learning

open access: yes
Abstract Automated detection of lathe checks in wood veneers presents significant challenges due to the variability of lathe checks characteristics and the natural properties of wood. This study explores the use of two convolutional neural networks (U-Net architecture) to enhance the precision and efficiency of lathe checks detection in poplar ...

Experimental Evaluation of Turning AISI 304 Using Minimum Quantity Lubrication With Vegetable‐Based Green Cutting Fluids

open access: yesMetalMat, Volume 3, Issue 1, March 2026.
This study experimentally evaluates the performance of eco‐friendly vegetable‐based cutting fluids—coconut, sunflower, and palm oils—during turning of AISI 304 stainless steel under minimum quantity lubrication. Palm oil exhibited superior lubrication and cooling characteristics, yielding the lowest cutting force, temperature, and surface roughness ...

Comparison of the Dynamic Cut‐Out Failure Modes of Common Proximal Femoral Fixation Devices Using a Mesh‐Free Computational Method

open access: yesJournal of Orthopaedic Research, Volume 44, Issue 2, February 2026.
Migration and cut‐out of DHS, Gamma3, PFNA‐II, and TFNA were compared under dynamic loading in a stable intertrochanteric fracture benchtop foam model and a mesh‐free simulation. No significant differences in force at cut‐out were observed, but simulation revealed that the volumes of damaged bone foam were 15%, 32%, and 25% higher for the Gamma3, PFNA,

Intuitionistic Fuzzy TOPSIS‐Based Ranking Alternatives of Machining Performance of Ultrasonic‐Assisted Turning in Fabricated Magnesium Alloys for Sustainability

open access: yesJournal of Engineering, Volume 2026, Issue 1, 2026.
This study is aimed at optimizing the machining performance of magnesium alloys in ultrasonic‐assisted turning (UAT) by enhancing surface quality, tool life, and overall efficiency while minimizing tool wear and energy consumption. Magnesium alloys were fabricated using a bottom‐pouring stir casting technique with commercial pure magnesium (99.9 ...

Shear Wave Optical Coherence Elastography and Structural Analysis of the Postnatal Mouse Cornea through Development

open access: yesJournal of Biophotonics, Volume 18, Issue 12, December 2025.
This paper investigates the geometrical and biomechanical properties of neonatal eyes at the early stages of development. We found that the corneal thickness is uncoupled from elastic wave speed and that the content and organization of the cornea primarily influence its mechanical properties.

Online measurement of veneer lathe checks

open access: yes, 2015
The present work deals with online lathe checks measurement. It is one of the most critical defects of veneer (leading to handling difficulties, excess of glue consumption, poor veneer surface quality, etc.). It could be characterized by lathe checks depth or frequency but these indicators require tedious measurements of the veneers.
