Here is an example to demonstrate these advantages. The EvidentOLS5000 microscopewas used to measure the surface roughness of a G21 needle (outer diameter: 0.8 mm). The image below shows data from a single field of view (measurement area: 256 µm × 256 µm, magnification: 1,080X):...
Use a roughness gauge for higher precision. A roughness gauge works by tracing the surface you want to measure. In addition to roughness, it usually also records multiple other parameters such as waviness and form. Nowadays, you can buy hand-held roughness gauge, which makes checking for surfac...
However, this specular reflectance measurement attachment cannot be used to measure the diffuse light reflected from samples with a rough surface. Other benefits electropolishing has over mechanical polishing include the following: One significant benefit of a highly polished surface is its smoothness. A...
However, over the last two decades, a higher level of complexity for surface metrology has been driven by the need for higher manufacturing efficiency and both cost and energy savings. Surfaces are now engineered to serve specific purposes, making the roughness parameter an even more crucial parame...
Although ANSI and ISO standards include many different parameters for measuring surface finish, functionality Ra (or average roughness) is by far the most common measure of surface finish. It is included in most specs, and is both a good starting point and a basic benchmark of process ...
for example, is rotational torque testing to measure drag. We make sure we are within the range that we want to achieve while in development, and we also perform this test while building the ball joints – since rotational torque will directly affect the performance and longevity of the part...

You can measure the peak runoff rate Q using a storm's Unit Hydrograph, the runoff of a storm over time for a location where rainfall collects in land, to the unit input of rainfall. This graph depends on the individual storm itself. Scientists and engineers create hydrograph...
