Complete Surface Finish Chart, Symbols & Roughness

Surface Finish is a measure of the overall texture of a surface that is characterized by the lay, surface roughness, and waviness of the surface. Surface Finish when it is intended to include all three characteristics is often called Surface Texture to avoid confusion, since machinists often refer to Surface Roughness as Surface Finish.

The Effect of Feed Rate and Cutting Speed to Surface Roughness

Dec 21, 2008· A simple theoretical model was proposed using the cutting speed and the feed rate as major parameters to predict the sensitivity of parameters on surface roughness of work piece. With the help of the experimental analysis, surface roughness of machined surface is measured and compared with predicted values using the theoretical method. In this case, depth of cut has no or little influence

Increase Surface Roughness on Hardened Stainless Steel

A shaft made from 440C is probably thru hardened rather than case hardened. If you wish to alter the surface roughness from the existing 12 microinch RMS to a 35-125 microinch RMS texture without affecting the shaft dimension, then there are processes like belt polishing, honing or abrasive blasting that should get the job done.If you want to precisely control both roughness and "lay", then
