Problem Statement
Coordinated utilization of systems engineering, modeling, advanced controls, and data analytics will enable energy efficiency improvement in the precision machining and hybrid manufacturing of metals/alloys to support cross-industry platforms, including aerospace and orthopedics.
Project Goal
The objective of this effort is to mitigate energy waste in manufacturing facilities, and specifically subtractive precision manufacturing, using model-based systems engineering principles.
Technical Approach
Integration of the following modules in the Smart Manufacturing Platform for precision machining: platform-based systems engineering to enable requirements formalization and reusability, multi-level, heterogeneous and hybrid modeling of manufacturing and ancillary equipment, predictive analytics for anomaly detection using sensory information and data analytics, context-driven supervisory control architectures enabling model/control interoperability, scheduling of manufacturing operations to maximize energy savings, big data analytics, reduction and secure IoT communication protocols.
