With the gradual development of the manufacturing industry towards intelligence and flexibility

the collaborative work of robots and machine tools can make the entire production process more efficient and flexible. However

traditional control systems and cloud computing services are unable to meet the demands of their data interaction. This paper proposes an open edge platform service architecture for robot – machine tool manufacturing units. The proposed solution is based on real-time Linux

with ROS and LinuxCNC open-source platforms as the core

and employs EtherCAT master station communication for the robot–machine tool collaborative control system. Fast DDS is deployed in the controller and server to achieve network access for different data

and container technology is utilized to build an edge microservice environment

enabling efficient data interaction and transmission. Finally

an experimental platform was set up

and system performance tests were conducted. The experiments verified the feasibility of the proposed solution.
