This video is about an explanation/description of numerical problem on surface roughness(Ra) irregularities/waviness of a profile(measured in microns or micrometre SI unit by profilometer(stylus/optical type) by centreline average method(CLA)(sum of positive absolute deviations divided by number of peaks/valleys/troughs) & root mean square(RMS)(addition of squares of irregularities)value mathematical formula in metrology and inspection/measurement/instrumentation in mechanical engineering.
