The aim is to create a common interface among machine tools of different technologies, manufacturers and model series.
The first part of the OPC UA Companion Specification for Machine Tools aims to provide the basics for such an interface. These allow for monitoring the machine tool and providing an overview of the jobs on it. Most of this information is not specific to a particular technology. The OPC UA for Machine Tools interface facilitates the exchange of information between a machine tool and software systems like MES, SCADA, ERP or data analytics systems.
The Machine Tool Specification was recently updated with Use Cases provided by OPC UA for Machinery, especially the Machine States Use Cases. They serve as the basis for further KPI Monitoring facets to enable calculations based on ISO 22400 KPI definitions.
