CNC system with enhanced interoperability

April 29, 2015 5:38 pm

NUM has developed a new communications interface option for its CNC systems that fully complies with the open MTConnect interoperability standard.
 Known as NUMConnect, the interface can be fitted to new or existing systems and simplifies the integration of CNC machine tools with third party manufacturing management software. It enables users to implement powerful productivity-enhancing real-time data collection and retrieval facilities for production monitoring and analysis purposes.
Manufacturers are increasingly making use of data retrieved from CNC machine tools on the shop floor to improve the efficiency of their production processes. However, until recently, the lack of a vendor-neutral data communications standard within the industry meant that CNC machine tool companies could only provide their customers with proprietary solutions for collecting and retrieving manufacturing data.
To compound the problem, most CNC systems have a closed architecture and only provide a data link via their PLC, limiting data collection to the PLC’s scan rate. The inflexibility of this approach – which also demands custom client software for each machine type – drove an industry initiative to bring Internet style connectivity to manufacturing equipment.
