Application of Robust Gaussian Regression Filter to Evaluation of Surface Roughness of Hardwood

Japanese	2001
Roughness Parameters for Evaluating Sanded Surface of Hardwood Parameters corresponded to tactile roughness
The quality of the sanded surface of wood and wood based materials is often classified by visual and tactile sense. The purpose of this study is to determine the roughness parameters corresponded to the tactile roughness to the automatic controll of the machining or the evaluation of wood surface.
