About

Wonkyun Lee is a researcher at the forefront of precision robotics and intelligent manufacturing, specializing in the intersection of robot machining, motion control, and process optimization. His work addresses a critical challenge in modern industry: enabling high-precision operations with inherently flexible industrial robot arms. Lee’s most impactful contribution is a framework for estimating and compensating cutting-force-induced position errors in robotic machining systems, a method that directly improves accuracy in automated manufacturing (15 citations). He further advanced precision control through a disturbance-observer-based dual-position feedback controller, which mitigates the low-stiffness limitations of multi-DOF robot arms for demanding applications (6 citations). In process optimization, Lee developed a novel approach to minimize cutting fluid waste by using motor current signals to regulate supply, enhancing both efficiency and sustainability (4 citations). His research, driven by the needs of the fourth industrial revolution, bridges the gap between robotic flexibility and the stringent accuracy required for industrial tasks. Lee’s work is essential reading for engineers and researchers aiming to deploy robots in precision machining, assembly, and material removal, offering practical solutions that balance performance with resource efficiency.
