ENHANCING COLLABORATIVE ROBOT COMMUNICATION WITH ELECTRICAL DISCHARGE MACHINE THROUGH MODBUS TCP INTEGRATION: A FEASIBILITY AND APPLICATION STUDY

Abstract

- This paper represents a detailed analysis of the synergy between unconventional electrical discharge machining (EDM) technology and collaborative robots. The authors have adopted a technological approach in this research, focusing on communication using the MODBUS TCP protocol between a collaborative robot and two electrical discharge machining (EDM) machines. By integrating the collaborative robot and EDM machines into the local network or organizational infrastructure, it has been demonstrated that these technologies can harmoniously function, efficiently communicating through a simple Ethernet cable. Intriguingly, the research illustrates how EDM machines can dynamically modify the values of registers within the collaborative robot, which acts as a server in this context. A conclusive case study has outlined the process of establishing communication infrastructure within the collaborative robot and showcased how it can implement and manage the necessary conditions for the manufacturing workflow. Through the use of existing industrial protocols, this research opens up fascinating possibilities regarding communication between collaborative robots and EDM machines. This could significantly reduce the complexity and costs associated with electrical I/O connections, enabling efficient transmission of multiple types of information between equipment using a single Ethernet cable. In essence, this paper offers a vision of the future where innovative technologies intersect and collaborate to streamline industrial processes while reducing the complexity and expenses associated with electronic connectivity.
