Abstract

Nowadays manufacturing industry is facing paradigm production changes, where mass customization is a fundamental pillar in adapting to changing market demands. Today's technology provides the necessary tools that, when integrated with human skills, give way to the Smart Industry thus entering an environment of industrial revolution 4.0. This paper proposes the design of a Digital Twin interface that supports the monitoring activity of the UR3 robotic arm while it performs the marking for surface cutting in the context of flexible production. The interface is achieved through a Human-Computer-Machine interaction (HCMI), while the self-adaptation to production and environmental changes is achieved through a cut and packing algorithm and a camera adapted to the robot, respectively. The interface is implemented and validated through a virtual laboratory case study in which it is observed that the Digital Twin replicates the movement of the robot with a negligible latency time.
