Tool Condition Monitoring (TCM) is considerably vital in the manufacturing industry. In this paper, an indirect TCM approach is introduced with a wireless triaxial accelerometer. The vibrations in the three vertical directions (x, y and z) are acquired during milling operations, and the raw signals are de-noised by wavelet analysis. These features of de-noised signals are extracted in the time, frequency and time\u2013frequency domains. The key features are selected based on Pearson\u2019s Correlation Coefficient (PCC). The Neuro-Fuzzy Network (NFN) is adopted to predict the tool wear and Remaining Useful Life (RUL). In comparison with Back Propagation Neural Network (BPNN) and Radial Basis Function Network (RBFN), the results show that the NFN has the best performance in the prediction of tool wear and RUL.<\/jats:p>","DOI":"10.3390\/s16060795","type":"journal-article","created":{"date-parts":[[2016,5,31]],"date-time":"2016-05-31T10:40:18Z","timestamp":1464691218000},"page":"795","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":151,"title":["Tool Condition Monitoring and Remaining Useful Life Prognostic Based on a Wireless Sensor in Dry Milling Operations"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5887-0514","authenticated-orcid":false,"given":"Cunji","family":"Zhang","sequence":"first","affiliation":[{"name":"School of Mechanical and Automotive Engineering, South China University of Technology, Guangzhou 510640, China"},{"name":"Department of Information Engineering, Guangxi College of Water Resources and Electric Power, Nanning 530023, China"}]},{"given":"Xifan","family":"Yao","sequence":"additional","affiliation":[{"name":"School of Mechanical and Automotive Engineering, South China University of Technology, Guangzhou 510640, China"}]},{"given":"Jianming","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Mechanical and Automotive Engineering, South China University of Technology, Guangzhou 510640, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0564-154X","authenticated-orcid":false,"given":"Hong","family":"Jin","sequence":"additional","affiliation":[{"name":"College of Engineering, South China Agricultural University, Guangzhou 510642, China"}]}],"member":"1968","published-online":{"date-parts":[[2016,5,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"693","DOI":"10.1007\/s00170-004-2038-2","article-title":"State-of-the-art methods and results in tool condition monitoring: A review","volume":"26","author":"Rehorn","year":"2005","journal-title":"Int.
