| Research Abstract |
In brain surgery, application to the fixture of polylactic acid material is expected, Because, it is for polylactic acid producing neither excelling in biocompatibility, nor an artifact. This research is aimed at construction of the micro fabrication method which controls the micro-crack generated on the machined surface.
As a result of detailed observation about the micro-cutting behavior in a fundamental orthogonal cutting using a high-speed video camera, shear angle during cutting of this material showed the same tendency as a plastic material, and shows a very large angle. Moreover, the viscoelastic property and the cutting temperature of material were measured and it showed clearly to create the machined surface of crack-less in case of the cutting-temperature conditions similar to glass transition temperature.
