Effect of Different Cooling Strategies on Surface Topography, Microstructure and Residual Stress of Turned γ-TiAl Alloy

This study investigates the surface integrity of γ-TiAl alloy during turning under different cooling strategies and reveals the regulation mechanisms of cooling conditions on surface morphology, plastic deformation, microstructure, and residual stress. Turning experiments were co...

Thermal error prediction for gantry guideway grinder spindle based on CNN-BiLSTM-Attention

Abstract Aiming at the strong nonlinearity, time-series lag, and multi-physics coupling characteristics of spindle thermal error in gantry guideway grinders, as well as the insufficient feature extraction and poor generalization ability of single deep learning models under varyin...
