Evaluation of Surface Roughness on the Basis of Three-Dimensional Parameters Using Computer Vision System:Part-II

In part-1 of the paper, a new convenient and comparatively less expensive technique for the evaluation of surface roughness has been presented. Various three-dimensional statistical parameters have been proposed for the comparison of surface roughness of the test surface with standard surface. In this part of the paper, a variety of surface specimens with different roughness values, various types of lay-patterns, with and without any error (defect) and similar as-well-as different materials, have been taken for the comparison/analysis of the surface roughness. The observations and the results of the comparison/analysis of the surface roughness have been presented for the various cases using the method as proposed in part-1. In addition, the comparison between standard and test surfaces is also carried out and illustrated by graphical representation.
