| Outline of Final Research Achievements |
Fundamental research on micro structure control in laser assisted incremental sheet metal forming process, basic function of which was forming a flat metal sheet into a complicated curved shape, was conducted.This process will be useful for titanium or stainless steel medical prostheses, also conventional sheet metal press operations.
First, by using experimental and numerical means, it was confirmed that the strain introduced by incremental forming process was very large. Next the formability and the surface roughness evolution in stainless steel thin sheet that had small grains were examined systematically. Last, the micro structure of heat-treated incremental sheet metal formed products were observed with electron backscatter diffraction method.
