Remaining Useful Life Prediction of Milling Tool Based on Pyramid CNN

open access: yesShock and Vibration, Volume 2023, Issue 1, 2023., 2023
Remaining useful life prediction of a milling tool is one of the determinants in making scientific maintenance decision for the CNC machine tool. Predicting the RUL accurately can improve machining efficiency and the quality of product. Deep learning methods have strong learning capability in RUL prediction and are extensively used.
