Effect of the tracing speed and span on roughness parameters determined by stylus type equipment

In this work, the effect of the scanning speed and the spacing in a roughness measurement was studied on the reference specimen using “TALYSURF CLI 1000” Profilometer. Microfiltration with ratio of 2.5 μm and Gaussian filter 800 μm was used. “TalyMap Platinum” software was used to analyse the data. Contact types of measurements were taken with inductive gauge using 2 μm radius stylus. Design of Experiments (DOE) and Analysis of Variance (ANOVA) tools were employed in this study to conduct the experiments and validate the results. The profile parameters Ra, Rq and Rz and the Surface parameters Sa, Sq and Sz were selected as the response variables for the roughness. The study reveals that the scanning speed has the significant effect on only Ra, Rz and Sa and Sz measurements and the spacing has the significant effect on all the Profile and surface measurements.
