Abstract

The stylus instrument is the most common form of instrument used in industry to measure surface texture. As the stylus is the only active component in contact with the surface being measured it is important that its dimensions and shape are accurately known. Measurements of the shape of four styli with different radii were made using four different measurement techniques. Of the four techniques only the scanning electron microscope (SEM) provided an absolute measurement of radius. Use of a roughness artefact proved to be the most efficient method for checking stylus radius. A further seven styli were measured using on SEM.
