Thermal errors in fused deposition modeling (FDM) machines can reduce dimensional accuracy by altering the nozzle position due to non-uniform heating of the nozzle and the build platform. While previous studies have mainly emphasized part distortion, the workspace-dependent thermal deformation of the printer structur...

Thermal drift is a major source of dimensional inaccuracy in CNC machine tools. This study presents an integrated framework that combines finite element (FE) thermal validation, synchronized multi-sensor temperature and displacement measurements, and Bayesian optimization of hybrid deep learning architectures for axi...

Finite element analysis (FEA) is used to investigate the modal characteristics of a vertical grinding machine, with the aim of aligning simulation conditions with real-world phenomena. Experiments were conducted using a percussion hammer, accelerometer, and spectrum analyzer to validate the findings. The analysis cover...
