Research on Strategies, Methods and Approaches for Applying CAD/CAM/CAE Technologies and Their Integration in Cyber-Physical Production Systems

Abstract

Cyber-Physical Production Systems (CPPS) have emerged as one of the most important technological paradigms in Industry 4.0,  enabling manufacturing systems to become intelligent, interconnected, and adaptive. A key foundation for CPPS development is the integration of engineering technologies such as Computer-Aided Design (CAD), Computer-Aided Manufacturing (CAM), and Computer-Aided Engineering (CAE). These tools provide digital representations of products, processes, and system behaviour, but remain  fragmented in many industrial contexts.
This paper investigates strategies, methods, and standards supporting CAD/CAM/CAE integration in CPPS architectures. A multi-level integration framework is proposed, linking engineering backbone systems, semantic interoperability models, real-time operational connectivity, analytics, and closed-loop optimization. The role of industrial standards such as OPC UA, AutomationML, STEP-NC, Asset
Administration Shell, FMI, and ISO digital twin frameworks is analysed. Extended case studies from automotive machining, robotic  welding, and smart assembly demonstrate the practical benefits of closed-loop manufacturing integration.
