Abstract

The surface profiles of eight aluminum discs were scanned after each sample was buffed with an electric buffer. This experiment seeks to determine whether or not a buffer is an effective instrument for creating a smooth surface at the microscopic level. The samples were buffed with three buffing wheels of the following grit in sequential order: 120, 180, and 240. They were then scanned using a stylus profilometer in two perpendicular paths. The resulting profile graphs displayed a wide range of surface roughness among the samples, with only one of the samples meeting the defined criteria of a microscopically smooth surface. Therefore, additional methods must be sought out for accomplishing this task.
