| Research Abstract |
Leather texturing is one of the surface decoration technologies for plastic parts. This manufacturing process has been dependent on manual work using chemical etching for graving textures on die surfaces. It hinders generation of aesthetic decoration. Recently NC milling machines are applied using digital 3D data of the leather textures. In this study methods for generating texture data by scanning real leather samples with an X-rays CT scanning system (XCT) was proposed. We developed a method to improve scanning accuracy of XCT and also a method to extend the scanned texture data of a limited area to arbitrary larger areas needed to cover a part surface to be decorated. For the former issue, we found artifact is critical factor for the accuracy and was reduced by our new correction method. For the latter we extended a texture synthesis method to be optimal for leather textures. Leather texture data was applied to a real manufacturing to produce cases of mobile phones made of plastic.
