Case Study: Unsupervised Overheat & Distortion Detection
Description: An unsupervised defect detection framework integrates time-series analysis with image-based analytics from coaxial dual-wavelength pyrometers. A CNN-based architecture converts sparse pyrometer data into feature-rich images for detecting overheated regions and part quality issues without relying on labeled training data.
Outcome: Successfully identified global and localized defects, including cracks and overheating regions, providing human-interpretable visual outputs for real-time monitoring. Example: Overhanging cantilever temperature differences.

Case Study: McGAN for Injection Molded Parts
Description: The Manufacturable conditional GAN (McGAN) framework uses instance segmentation (Mask R-CNN) to segment 2D part images into features. Each manufacturability rule (e.g., rounding corners, draft angles) is embodied in a conditional GAN (Pix2Pix) to modify feature shapes.
Outcome: Modified designs showed high quality from a manufacturability perspective, addressing typical molding limitations in 2D.
