画像処理を用いた金型磨き面の判定

抄録

In mold manufacturing, hand-polishing with grindstones is finally conducted to keep the mold surface uniform and smooth. After hand-polishing, it is necessary and important to evaluate if the surface is polished enough. This evaluation has been usually dependent on the experience and intuition of skilled workers. This study has developed the automatic evaluation of the polished surfaces using image processing. First, we investigated the features of the polished surfaces, based on the interviews to skilled workers, and attempted to extract these feature quantities by image processing. The surface evaluation by image processing had good agreements with that by a skilled worker.
