A products exterior cover, a vehicles dashboard, a machined panelthe differences in appearance, specifically whether something is shiny and smooth or rough and matte, are due to the difference in surface roughness. Often engineering drawings call for a range of surface roughness. Surface characterization techniques for determining the. Im looking for the optimal method for measuring roughness. Im concerned about current measurements and measuring methods. This study is concerned with measurements of surface roughness of holes drilled in a cortical bone using two drilling techniques. What are the different methods to measure the roughness of. As mentioned by cg li above, surface profilometer is one among many techniques to measure surface roughness. Before calculation of roughness parameters, the height data are. The rms roughness values for the ground sample varied by nearly a factor of 2 and over 400 times for the smoother partially polished sample for different measurement techniques and different spatialfrequency ranges. Hence, the inspection of surface roughness of the work piece is very important to assess the quality of a component.
