Digital Twin Testbed in Cyber Physical Systems Towards Smart Manufacturing of Small and Medium-sized Manufacturers

Abstract

This paper introduces a digital-twin testbed in a cyber-physical, manufacturing-systems environment. The physical environment is based on a customized manufacturing line that includes a 3D printer, a machine tool, an inspection machine, a robot handler, and a buffer. The cyber environment of this testbed includes a 3D visualization of the line and several data-analytics models. The digital twin testbed is implemented by connecting the physical environment with the cyber environment via two types of the interfaces. The resulting integrated testbed can be a useful instrument when manufacturing engineers implement cyber physical systems for the first time their smart factories.
