Tanaka Lab
Machine-translated · View original
A lab creating new machining technologies that use lasers, ultrasound, and vibration.
AboutAbout the lab
New machining technologies through high energy and vibration
The Tanaka Lab studies production and machining technologies that underpin manufacturing.
It develops laser machining technology that controls the properties of light, and ultrasonic technology for creating fine surface textures and narrow, deep holes.
The lab also studies how the structures of machines and machine tools vibrate, and develops dampers whose stiffness and damping performance can be adjusted.
Key terms
- Burnishing
- Machining in which a hard tool is pressed against a surface to flatten fine irregularities, producing a smooth, durable surface
- Damper
- A component or device that absorbs the energy of vibration to reduce shaking
- Stiffness
- Resistance to deformation when force is applied; the higher the stiffness, the less the shape changes

ResearchResearch themes
Aiming to build innovative intelligent manufacturing systems, the lab studies production and machining, machine elements, and design analysis. It develops new machining and element technologies that use high energy and vibration.
*Illustrative imageA burnishing tool that keeps force constant
The lab is developing a tool for burnishing, which smooths a surface by pressing a hard ball against it, that can control the pressing force even during machining. The goal is to create a uniform surface layer even on complex curved surfaces.
*Illustrative imageP-DACS, a damper that suppresses vibration
This damper combines a metal structure with a specially designed stiffness and a polymer material that absorbs vibration well. Stiffness and vibration damping can be adjusted over a wide range to suit the application.
