Abstract: Predictive maintenance (PdM) in CNC machine tools has gained significant attention due to its potential to reduce downtime and increase operational efficiency. This paper explores automated diagnostic techniques used in predictive maintenance for CNC machines, focusing on fault detection, prognosis, and decision-making processes. With the advent of Industry 4.0, intelligent sensors and data analytics have revolutionized machine monitoring, enabling the prediction of failures before they occur. The integration of real-time monitoring systems, vibration analysis, acoustic emission monitoring, and machine learning algorithms has proven effective in diagnosing potential failures. This paper provides an in-depth review of various approaches to automated diagnostics, highlighting the advancements in machine learning models, artificial intelligence (AI), and the Internet of Things (IoT) technologies in enhancing PdM. The research also examines the challenges associated with implementing PdM systems, such as data acquisition complexities, sensor calibration, and computational costs. Through case studies and application examples, the paper discusses how these diagnostic systems can optimize maintenance schedules, minimize machine downtime, and improve overall productivity. The objective of this research is to provide a comprehensive understanding of automated diagnostic methods and their role in predictive maintenance systems for CNC machine tools. The hypothesis posits that the application of advanced diagnostic techniques using AI and IoT will lead to a significant reduction in unplanned downtime and maintenance costs. The findings suggest that the continued development of predictive maintenance systems can lead to improved reliability and lifespan of CNC machines, benefiting industries where precision and continuous operation are critical.
