Factors Affecting Surface Roughness and How to Improve ...
· Surface roughness, often shortened to roughness, which is defined as the shorter frequency of real surfaces relative to the troughs, is quantified by the deviations in the direction of the normal vector of a real surface from its ideal form. If these deviations are large, the surface is rough; if they are small, the surface is smooth. It is an important index to tell whether a machined part is ...Get Price
Three ways to achieve a specific metal finish
Nov 05, 2019 · Measuring these is critical if an operation needs to produce a measured finish. Quality personnel measure the surface roughness with a profilometer, which determines Ra values by moving a diamond stylus across the surface for a specified distance and using a specified contact force. They then assign the Ra value as an average of the surface ...Get Price
