AI-Driven Innovations in Mechanical Engineering: From Smart Manufacturing to Predictive Maintenance

Review Article

Abstract

Artificial Intelligence (AI) has become a pivotal driver of innovation in mechanical engineering, fundamentally transforming the design, operation, and maintenance of mechanical systems. By leveraging advanced algorithms, machine learning, deep learning, and computer vision, AI enables unprecedented levels of automation, precision, and efficiency in engineering processes. In smart manufacturing, AI facilitates real-time monitoring, adaptive control, and predictive decision-making, allowing production systems to optimize performance, reduce downtime, and enhance product quality. Predictive maintenance, powered by AI, leverages sensor data and predictive analytics to anticipate equipment failures, minimize operational disruptions, and extend machinery lifespan, resulting in significant cost savings. Design optimization benefits from AI-based simulation, generative design, and topology optimization techniques, enabling engineers to create high-performance components with reduced material usage and improved durability. Additionally, AI-integrated robotics improves automation, precision, and safety in complex manufacturing tasks, while AI-driven quality control uses computer vision and anomaly detection to ensure superior product standards. This paper reviews the current state-of-the-art AI applications in mechanical engineering, highlighting key methodologies, practical implementations, and emerging trends. It also identifies challenges related to data integration, model interpretability, and human–machine collaboration, offering insights into potential research directions. By consolidating these advances, the study demonstrates how AI not only enhances operational efficiency and safety but also accelerates innovation in mechanical engineering. The findings underscore the strategic importance of AI adoption for future-ready engineering practices, emphasizing its transformative impact on both industry and academia.
