A Generalised Approach on Kerf Geometry Prediction during CO2 Laser cut of PMMA Thin Plates using Neural Networks
(2021)This study presents an application of feedforward and backpropagation neural network (FFBP-NN) for predicting the kerf characteristics, i.e. the kerf width in three different distances from the surface (upper, middle and ... -
An investigation of surface quality characteristics of 3D printed PLA plates cut by CO2 laser using experimental design
(2021)In this work, two typical surface characteristics, i.e., mean surface roughness and angle of the kerf during laser processing of 3D-printed Polylactic Acid (PLA) plates with 4.00 mm in thickness, are investigated. A carbon ... -
Laser cutting of 3D printed acrylonitrile butadiene styrene plates for dimensional and surface roughness optimization
(2022)3D printing (3DP) of polymers using fused filament fabrication (FFF) is not yet massively adopted in industrial environments due to shape accuracy and surface integrity limitations. However, the FFF process combined with ... -
Replacing the metal electrodes in triboelectric nanogenerators: High-performance laser-induced graphene electrodes
(2020)While significant work is being carried out to develop materials for enabling high surface charge density triboelectric nanogenerators (TENG), little attention has been paid to the role of electrodes responsible for charge ... -
Surface characteristics investigation of 3D-printed PET-G plates during CO2 laser cutting
(2022)This study investigates the influence of the stand-off distance (SoD), laser speed (LS) and laser power (LP) on kerf geometry (upper width Wu, down width Wd and kerf angle KA) and mean surface roughness (Ra) during CO2 ...
