Industry 4.0 is one of the foremost that drives the modern industrial revolution with the latest technologies, which comprises smart equipment, machinery and control systems. In this, digital manufacturing integrates the traditional manufacturing systems with the latest digital technologies for modelling, analysis, optimization and automation of manufacturing processes. This study analyses the application of various advanced technological tools for implementation of digital manufacturing. Based on content analysis, combined applications of digital manufacturing tools and advanced manufacturing technologies are framed and various technological trends identified. Integrated and automated machines can do repetitive works and humans can do complicated works through creativity and problem-solving capacity through technological tools. This paper support to identify the digital manufacturing obstacles in implementation and also helps to understand the digital manufacturing within the framework of the nine technological tools and it also recognizes that correlation with other technologies. In digital manufacturing, a huge manufacturing data can be analyzed with the big data analysis and stored in cloud for future use and secured with the cybersecurity technology. Simulation carried out to test digital model before implementation and monitoring with the digital twin technology. Virtual reality integrates the real-world with virtual environments and taking decisions through Internet of things. Robotic system enables to automate works and additive manufacturing technology develops the components from the stored data.
