Onto Innovation’s Tucson-based subsidiary 4D Technology announced the launch of the 4Di InSpec™ SR roughness measurement system - a novel, portable, vibration-immune optical system for high-precision 3D surface roughness measurement at the point of use.

Mitutoyo America Corporation announced the release of the new Surface Roughness Tester SJ-220 Series to its line of Form Measuring Instruments, providing compatibility and versatility to meet the diverse needs of manufacturing sites.

Olympus’ high-quality optics help eliminate many outliers before they occur. The quality of the resulting measurement is evident in multiscale analysis down to the finest scales.

Specifications for surface texture frequently focus on surface “roughness”—the finer structures in the texture—often to the exclusion of the “waviness”—the larger structure of the texture. Unfortunately, problems related to sealing, vibration, noise, wear, etc., are regularly caused by issues hidden in the waviness domain, which cannot be captured by common roughness specifications.

Sensors are an essential part of a metrology system, and there are several key factors that inform a buyer’s choice. These include ease of use, accuracy, speed and cost. Comparing the options can involve both analysis of features and actual demonstration of capabilities, but to get meaningful information for either you have to ask the right questions.

As part tolerances tighten, both form and surface finish have a bigger influence on the size and function of the product. And with pressures on manufacturing to be more productive, it is no longer viable for checks of surface or form to be performed on a measuring system in a quality room.

How does the surface texture affect the friction between two dry parallel sliding surfaces? It turns out that this problem has challenged some of the greatest minds in science and engineering.
