Research Content
【Ultrasonic Vibration Cutting and Grinding】
Ultrasonic vibration cutting and grinding are a machining process that applies ultrasonic vibrations to tools. The advantages of this method include:
・Reduced cutting and grinding resistance for difficult-to-machine materials
・Inexpensive and high-speed creation of fine textures
We are conducting research focusing on the processing mechanism of this technique and the imparting of functionality to workpieces through these textures.
【Metal Precipitation in Glass】
We are investigating the unique phenomenon of forming dendritic metal crystals within glass. By elucidating the mechanism of this phenomenon, we are exploring possibilities for in-glass wiring and internal processing.

Imaging of internal stress distribution in workpieces using photoelasticity
A Day in the Lab
The lab encourages an open atmosphere between seniors and juniors, creating an environment where it’s easy to ask questions when something is unclear. Seminars are held every weekday morning at 8:00 AM, with presentations occurring approximately once a week. Mondays are dedicated to learning seminars, where assigned presenters share materials they have learned. From Tuesday to Thursday, progress seminars are held, where students are divided into groups by research topic and report on their weekly progress for the week. Fridays are paper seminars, where assigned presenters discuss papers they have read.
Creating slides and presenting every week is demanding, but it significantly improves presentation skills. It also makes it easier to manage your own research progress.
