Measurement of surface finish in industrial manufacturing has traditionally been done by means of either visual comparison with reference plates or by the use of contact stylus based profilers. There are many challenges associated with contact profilers such as stability during measurement in an ...
You get the best finish when you can surface with a single pass of the cutter. This becomes difficult on wide plates. It's one reason why fly cutters are popular, aside from being cheap: they cut a wide swath. But not all fly cutters are equal. It's nice to have one that cuts th...
The optical parts included surface mirrors and glass flats with various thin-film coatings (antireflective [AR], tin oxide, or indium tin oxide), as well as blank glass plates for comparison. The coatings were applied by simply pouring the coating over the surface at a slow rate to achieve...
As a result, a bright finish is achieved and a typical application would be hollow ware. Acid and alkaline etching is commonly used for lithographic plates, electrolytic capacitors and nameplates to mention but a few. Etching requires a chemical reagent to attack and roughen exposed surfaces of ...

surface finish improvement. Relevant finishing techniques using abrasives and non-conventional techniques, such as grinding, polishing, laser, peening, buffing, and electrochemical polishing are reviewed, and typical results are documented for different AM processes. Limitation of each process and enhancing...
In this embodiment of the present invention, the surface roughness value of the work roll corresponds to the surface roughness value of the surface finish of the metal substrate, such as a finished sheet product. Inspection of the work roll at step 60 includes the comparison of the final work...
FSP has led to the decrease in COF (Figure 8.9) of samples in comparison to BM. Moreover, increasing the number of FSP passes has led to a decrease in the amount of mean COF. These results can be attributed to the differences in the extent of localized plastic deformation at real ...
Diver assessment of blade surface roughness can be adequately made using the Rubert comparator gauge, which allows a tactile comparison of a blade surface with six replicas of blade roughness, ranging from best possible new finish to serious degradation. A detailed account of propeller surface ...
