Abstract
Measuring surface roughness is vital to quality control of the machined workpiece. In recent years, vision systems have made image analysis easier and more flexible for measuring surface roughness by using texture features. In this paper, the texture features of the grey-level co-occurrence matrix (GLCM) have been utilized to estimate surface roughness of specimens machined by turning operations. The relationship between GLCM texture features and surface roughness has been investigated to discover which texture features can be used to estimate surface roughness. The correlation coefficient between each texture feature and the arithmetic average height (
