About

Deyang Feng is a leading researcher in advanced manufacturing and robotic automation, with a particular focus on precision machining of difficult-to-process materials. His most influential work addresses the challenge of automating surface finishing for titanium alloy components, which are critical in aerospace and biomedical applications due to their strength but notoriously difficult to polish. Feng’s landmark 2015 paper, cited over 50 times, introduced an automatic robotic polishing system that integrates a compliant end-effector with force sensing and position-based explicit force control. This innovation enables consistent, high-quality surface finishing on curved titanium parts—a task previously reliant on skilled manual labor. By developing a closed-loop force/position control architecture, Feng solved the fundamental problem of maintaining optimal contact pressure during robotic polishing, significantly reducing defects and improving process reliability. His contributions bridge the gap between traditional manual finishing and fully automated precision manufacturing, offering a scalable solution for high-value industries. Feng’s work continues to influence research in robotic machining, adaptive control, and intelligent manufacturing systems.
