Abstract

A new era of production known as “Smart Manufacturing,” which is primarily motivated by the ideas of Industry 4.0, has been brought about by the quick development of digital technologies. The goal of this technology revolution is to develop intelligent, adaptive, and networked production systems that react instantly to shifting supply, demand, and operating circumstances. The Internet of Things (IoT), artificial intelligence (AI), machine learning (ML), cyber-physical systems (CPS), big data analytics, additive manufacturing, digital twins, and augmented reality (AR) are some of the main technologies that are at the core of smart manufacturing. These technologies enable seamless communication between machines, advanced data analytics for decision-making, enhanced automation, and improved resource efficiency. This review article provides a comprehensive analysis of these enabling technologies, discussing their roles, benefits, and real-world industrial applications. Furthermore, it examines critical integration strategies required to harmonize these technologies within existing manufacturing infrastructures. These strategies include interoperability through standardized communication protocols, the use of cloud and edge computing for distributed data processing, robust cybersecurity measures to safeguard digital assets, and workforce upskilling for human-machine collaboration. The paper also highlights how smart manufacturing is being implemented across various sectors, including automotive, aerospace, electronics, and consumer goods, demonstrating its versatility and transformative potential.
