Tool Wear State Identification Based on SVM Optimized by the Improved Northern Goshawk Optimization. [PDF]
Sensors (Basel), 2023 Tool wear condition significantly influences equipment downtime and machining precision, necessitating the exploration of a more accurate tool wear state identification technique. In this paper, the wavelet packet thresholding denoising method is used to process the acquired multi-source signals and extract several signal features.
