Intelligent Recognition Method of Turning Tool Wear State Based on Information Fusion Technology and BP Neural Network

Abstract: The multi-information data acquisition system of tool wear condition of CNC lathe is built by acquiring the acoustic emission and vibration acceleration signals. The data of acoustic emission and vibration acceleration signals during the process of CNC machine tool processing under the conditions of different tool wear degrees and different cutting conditions are acquired and analyzed using the orthogonal experimental method. The optimum characteristic frequency band of acoustic emission and vibration accelera… Show more

“…Chen et al said that the new upsurge of machine translation in the 1970s was also related to automatic retrieval and artificial intelligence [ 7 ]. Xu et al said that with the progress of modern science and technology, machine translation in the 1970s was no longer a topic of natural language processing [ 8 ]. Sreelekha et al said that to establish various information retrieval systems, it is necessary to automatically index documents and even use computers to process natural languages.…”
