An exploratory study on CNC machine technologies, barriers and opportunities on adopting Industry 4.0: a review

Industry 4.0 represents a complete digital transformation in the way companies operate, incorporating advanced technologies. It includes or integrates new technological advances such as additive manufacturing, artificial intelligence, augmented reality, cyber-physical systems, blockchain, cybersecurity and other technologies. While Industry 4.0 and similar technologies offer many conceivable benefits for production, automated machines are essential for driving industries forward. This article proposes an exploratory investigation in the adoption of Industry 4.0 by CNC machine users, focusing on main barriers and opportunities, exploring the challenges faced by these companies and identifying the potential opportunities arising from adoption. It is based on an exploratory systematic review of the literature. The consolidated factors were grouped into categories to help understand the challenges faced by companies in the transition to Industry 4.0. This research identified several barriers for companies using CNC machines, while also highlighting numerous opportunities related to the adoption of Industry 4.0.
