PROJECT LEAD

Virginia Tech

PARTNERS

University of Virginia, Pennsylvania State University, Arconic, Commonwealth Center for Advanced Manufacturing

PROBLEM STATEMENT

  • Wireless sensor nodes impacted by electromagnetic, vibration, and thermal noise
  • High volume of data raises challenges related to data transfer and processing
  • Complex, nonlinear, dynamic mfg systems - challenges in real time decision making
  • Existing sensor based decision making models are computationally complex

PROJECT GOAL

Demonstrate energy efficient metal material processing at Arconic facility through advanced sensing, automated process monitoring and model based controls.

TECHNICAL APPROACH

  • Self-powered wireless sensor nodes and deployment of energy harvesting approaches; Efficient computational framework to acquire, post-process, and synthesize large quantities of sensory data in real time; In-process monitoring capability with offline big-data analysis techniques; Closed-loop system to enable real-time, model-based control for energy consumption optimization.
