Abstract

A Manufacturing Process Digital Twin is highly useful in Process Control, since it shows adaptiveness and near-real-time responsivity. However, cloud architectures are in place, or more commonly, CPS-based modules communicate through IoT technology, implicating security (data-related) and safety (concerning proper control enforcement). With respect to Thermal Processes, and in particular Laser Welding, this work studies the effect of encoding on Process Control efficiency. More specifically, compression and encryption are applied to control signals and the process control efficiency is studied. The simulations used to this end are considered to be part of a digital twin.
