About

Dr. Chenggen Nan is a researcher specializing in precision robotic manufacturing, with a particular focus on improving the accuracy of automated drilling processes for large-scale industrial assemblies. His work addresses a critical challenge in aerospace and heavy machinery: ensuring the perpendicularity of bolting holes on curved surfaces, where manufacturing deviations render CAD models unreliable. Dr. Nan’s major contributions center on developing and optimizing methods for normal direction measurement in robotic drilling. His seminal 2014 paper, "Normal direction measurement in robotic drilling and precision calculation," which has garnered 25 citations, establishes a foundational framework for measuring drill orientation relative to complex workpiece surfaces. He further refined these techniques in his companion work, "Optimization Design for Normal Direction Measurement in Robotic Drilling," demonstrating how precise hole alignment directly impacts the fatigue life and fluid dynamics of assembled structures. By addressing the gap between theoretical CAD models and real-world manufacturing errors, Dr. Nan’s research provides practical solutions that enhance the reliability and longevity of bolted joints in critical applications, marking him as a key contributor to the advancement of intelligent robotic manufacturing systems.
