The distance (pitch) between … WebThe roughness of a surface is a measure of the size and distribution of bumps and indentations on the surface. The largest and most noticeable bumps and indentations are called macro-texture. The smaller bumps and indentations are called micro-texture. Waviness The surface is smooth if the waves are small and evenly spaced.
WebSURFACE. FINISH. COMPARISON. CHART. RA is the arithmetic average deviation of the surface valleys and peaks and is often used to specify the roughness of a machined surface. RMS is the root mean square average of the profile height deviations from the mean line of the surface and is mostly used for optical surfaces. The term Micro means millionth.
