“…Other similar concepts are PHM (Prognostic and Health Management) found in Liu and Xu (2017), Machine Healthy Management discussed by Lee, Kim, Quan, Kim, Kim, Yooh et al (2018), Machine Healthy presented by Lee, Kao and Yang (2014) and SMTS (Smart Machine Tool Systems) discussed by Jeon, Yoon, Um and Suh (2020) which presented an architecture seeking to avoid machine failure and zero defect. Thyago Bachim, Mauro Luiz Martens, Salvatore Digiesi, Douglas Favero Trindade, Bruno Ricci Considering that companies in this sector of woodworking machine tools use few predictive maintenance systems, the use of prognostic maintenance or condition-based maintenance is currently a challenge because if the normal condition of the spindle during an empty test for offline vibration data collection is not known, then its operation with online monitoring as referenced by Mosyurchak, Veselkov, Turygin and Hammer (2017) is also unknown. These authors believe that it is important to differentiate between the types of collections performed for later determination of failures.…”
