NUMConnect allows CNC machine tool builders to add further value to their products very easily and cost-effectively, by providing uncompromised connectivity for manufacturing data. 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.

MTConnect is an open, royalty-free communication standard that can be used by anyone and it is rapidly becoming the preferred choice of the machine tool industry. The standard is managed by the MTConnect Institute – a not-for-profit organization that seeks to improve the use of real-data in manufacturing industries. A growing number of machine tool manufacturers are adopting the standard, which is also now supported by many leading suppliers of enterprise resource planning (ERP), manufacturing operations management and production dashboard software. NUM was one of the first CNC manufacturers to offer an MTConnect compliant interface for an entire product range which does not require the use of third-party or custom adapters. The company originally introduced the interface on its Axium product line in 2008 and is now making it available as an option across its entire range of CNC systems.
