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...
Machined metal parts may appear smooth, but they always have some amount of roughness due to any of several causes like vibration in the milling equipment, or worn cutting bits. Specifications will set an acceptable degree of roughness, but there's more than one way to measure the surface, a...
One of the tests we apply to our ball joints, 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...

For the first rough machining, use the meter card to measure the size of the boring blade higher than the large tool holder. The rough machining reserve is about 0.5mm on one side, which is convenient for semi-finishing. The main deflection angle of the boring insert is 30°, the flank...

Numerous groups were successful in using optical microscopes to measure topography in the 90s, based on interferometry techniques.6This allowed quick (seconds to minutes) non-contact roughness measurements. Areal roughness measurement methods have grown since then, to include confocal,7focus variation,8...

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...
