What is the difference between RA value and RZ value?

WebJul 14, 2024 · Ra averages all peaks and valleys of the roughness profile and then neutralizes the few outlying points so that the extreme points have no significant impact on the final results. Rz averages only the five highest peaks and the five deepest valleys—therefore, extremes have a much greater influence on the final value.”. http://www.cnccookbook.com.s3-website-us-east-1.amazonaws.com/Calculators/SurfaceFinishChartMeasureSymbols.html
