金属材料表面に微細パターンを有した材料の摩擦特性評価

抄録

It is clarified that the frictional properties for material surface is controllable by machining a micro-pattern on the surface. In the previous research, it is considered that strain of materials such as spring-back can be reduced by controlling the frictional characteristics in the blank holder during the press forming. However, evaluation only by the experiment is difficult due to huge combinations between the shape of micro patterns and the arrangement density. Therefore, evaluation by numerical simulations is necessary for present study. In this research, evaluation of effects by the differences of the shape of micro-patterns and the arrangement density is conducted by the experimental method and numerical simulation.
