Abstract
Improving materials surface function by introducing micro-textures is of great interest in various fields. The authors also have performed to improve the functions of photocatalytic surface by introducing the microcutting textures and confirmed an improvement in the hydrophilicity, which is one of the photocatalytic functions, because of increase in the real surface area. In this report, vibration assisted cutting is performed to fabricate more complicated surface micro-textures. As the first step, a modeling wax is cut by a sharply pointed triangular diamond tip vibrated by a fast tool servo system with micron order amplitude, and obtained cutting groove shapes are evaluated with considering the influence of tool face direction. As a result, it is found that the obtained cutting groove shapes reflect the vibration pattern with micron order amplitude regardless of the tool face direction, and the burr height around the groove shoulder by the tool edge cutting becomes much higher than that by the tool plane cutting.
