Abstract

In a smart manufacturing system, as machining cells comprise machines employing different types of computerized numerical controls (CNCs), the data exchange between multiple machines and information systems is very important. To secure interoperability between systems, standardized communication protocols such as OPC UA or MTConnect can be applied. Generally, by applying the standard protocol, the data acquisition module is implemented using the communication library provided by CNC makers, and the application is implemented in the required standard’s client development environment. Herein, we propose an integrated operation management system for multi-vendors’ CNC machine tools based on OPC UA and MTConnect to provide consistent data collection and utilization methods. The system architecture included a data acquisition module of OPC UA and MTConnect using the unified NC interface developed previously and an integrated database directly connected to both the clients; a reference data model was provided for each component to maintain data consistency.

Keywords:
