Dataset for various grit-size Abrasive sheets

The dataset comprises image files of size 640 x 480 pixels for various grit sizes of Abrasive sheets. The data collected is raw. It can be used for analysis, which requires images for surface roughness. The dataset consists of a total of 8 different classes of surface coarseness. There are seven classes viz. P80, P120, P150, P220, P320, P400, P600 as per FEPA (Federation of European Producers of Abrasives) numbering system and one class viz. 60 as per ANSI (American National Standards Institute) standards numbering system for abrasive sheets.

本数据集包含不同粒度尺寸的磨料纸图像文件，图像尺寸为640 x 480像素。所收集的数据为原始数据。可用于表面粗糙度分析，其中需要使用相关图像。数据集共包含8种不同类别的表面粗糙度等级。其中七种类别分别为P80、P120、P150、P220、P320、P400、P600，依照欧洲磨料生产商联合会（FEPA）的编号系统；另有一种类别为60，依照美国国家标准研究院（ANSI）的编号系统。
