Research on Prediction of Remaining Useful Life of Wheel Machining Tool Based on EMD–PSO–LSTM Model

The Journal of Engineering, Volume 2026, Issue 1, January/December 2026.
A novel EMD–PSO–LSTM framework is proposed for precise tool remaining useful life prediction in wheel machining, where empirical mode decomposition (EMD) extracts multi‐scale features from sensor data, and particle swarm optimization (PSO) enhances long short‐term memory (LSTM) hyperparameters, achieving superior robustness and accuracy.
