In-Process Sensing

EWI is currently conducting an applied R&D program to help small and medium-sized manufacturers (SMMs) use Industry 4.0 concepts and tools to improve operations. Recent work has resulted in the development of a system that can acquire, visualize, inspect, and analyze low- and high-frequency data collected from precision sensors to check the quality of machined...

Errors that occur during large-scale additive manufacturing (AM) builds can be prohibitively expensive for manufacturers. Current in-line inspection methods are inefficient, but damaged and distorted end products waste too much time, material, and money. How can in-process inspection be optimized to improve productivity and ensure quality? EWI investigated this question using the laser-blown powder DED...

In-situ process monitoring has been around for a while in most manufacturing industries – from the trained eye of a supervisor to an automated manufacturing execution system. Additive manufacturing (AM) is no different; it uses sensors to provide both a better understanding of the process and valuable data that can be analyzed to infer the...
