摘要
Vibration finishing which is a newly developed abrasive finishing method is often applied to the metal surfaces recently. However, an application of this finishing method and an evaluation of finished surfaces require skill which depends on sensory examination. This is because the relations between finishing conditions and quality of finished surfaces are not clear. And the quantitative evaluation of them has not been done. The aim of this research is to evaluate the vibration finished surfaces quantitatively. The vibration finishing was carried out using a disk-type finishing tool with movements of rotational and orbital motion on stainless-steel plate surfaces. For taking photos of finished surfaces, the finished surfaces were lit up with LED illumination from two directions and photos taken from two directions were analyzed for detecting the differences between them for estimating the finished surface characteristics. And a quantitative evaluation of the vibration finished surfaces was examined, using textural features calculated from the gray level co-occurrence matrix and 2-D DFT obtained from the surface images of them. As a result, differences of textural features between vibration finished surfaces and circular hairline finished surfaces were clarified. Moreover, effectiveness of the quantitative evaluation method was confirmed by comparing the evaluated results obtained from skilled workers.
