G-code informed reconstruction of high-resolution CNC machine data from low-sampling rate industrial data streams

Industrial Computer Numerical Control (CNC) machines provide access to operational data through standardized communication protocols like OPC-UA and MTConnect; However, these data streams are typically sampled at low and irregular rates, limiting their direct use for spatially resolved process analysis. Sparse reporting, variable sample counts across nominally identical ru…

An End-to-End Framework for Verifying and Validating Manufacturing Design Integrity

Cyber attacks on networked automated manufacturing systems can severely impact part quality. In fact, malicious modifications may be introduced at any point during the manufacturing lifecycle. Therefore, it is vital to verify and validate that manufactured parts conform to their designs. This chapter describes a formal, end-to-end framework that verifies and validates the…

Multimodal sensor fusion for real-time standoff estimation in directed energy deposition

In Laser Powder-based Direct Energy Deposition (LP-DED) systems, achieving consistency, precision and quality of produced parts requires tight control over printing parameters. One of the critical parameters is the standoff distance. Maintaining an optimal standoff height is crucial for achieving correct laser power density and powder catchment efficiency, as both laser an…
