Tetsuo Hase

About

Tetsuo Hase is a robotics and precision engineering researcher whose work has significantly advanced the field of automated mold polishing and compliant motion control. His research centers on the development of CAD/CAM-based position/force control systems for robotic polishing applications, desktop NC machine tools, and intelligent motion control for finishing metallic molds with complex curved surfaces. Hase's most influential contribution, "CAD/CAM-based position/force controller for a mold polishing robot" (2007), has garnered 152 citations, establishing him as a leading voice in robotic surface finishing. This work demonstrated how CL data with normal vectors could simultaneously guide tool trajectory and force direction — a critical innovation for achieving consistent, high-quality polished surfaces on intricate mold geometries. His subsequent research expanded this framework to industrial articulated robots and desktop orthogonal-type systems, incorporating capabilities such as stick-slip motion and fine-velocity pulse conversion to achieve positioning resolutions as fine as 1 μm. Through a sustained body of work spanning mold polishing robots to LED lens mold lapping systems, Hase has bridged precision mechanical engineering and intelligent control, producing practical solutions for manufacturing challenges that demand both positional accuracy and adaptive force regulation.
