Case Study
Driving Digital Transformation: Mazak Corporation
Mazak required a common, standards-based method to securely connect and derive value from the rich, raw data in its machine tools. An advanced security system suitable for IT and operations technology (OT) was necessary to protect from both internal and external attackers. The application needed to run on the network infrastructure on the factory floor, immediately transforming process, overall equipment effectiveness (OEE), and sensor data. The fog application needed to support the MTConnect specification for integration with existing systems and sensors. Real-time analytics were required to process high frequency vibration, temperature, coolant, and sound inputs to inform operator action and drive business support systems.
