CNC machine tools and basic manufacturing equipment have been listed as “strategic areas to accelerate breakthrough” in “made in China 2025”

and the high-end intelligent CNC system is the core component to ensure that CNC machine tools have high-speed

high-precision

compound

network

and intelligent functions. This paper proposes an open CNC system architecture based on microservice architecture. The CNC system is divided into a series of loosely coupled and independently deployed microservices by adopting the domain-driven design pattern to improve reconfigurability and scalability. Intelligent functions such as chatter suppression are packaged in microservices to realize hot-plug integration. An impeller cutting experiment is conducted. The results shows that the micro-service architecture intelligent CNC system has excellent dynamic expansion and reconfigurability

and the surface quality can be effectively improved after loading the intelligent algorithm.
