APPLICATION

Using BEX to measure 3D Surface Roughness from X-Ray Computed Tomography (XCT): applied to a Dental Artefact 3D X-Ray Computed Tomography (XCT) is widely used in medical imaging and increasing used in additive and traditional manufacturing, due to its ability to provide high quality imaging for complex 3D components. The Challenge – To apply XCT …

ELECTRICAL SWITCHING CONTACT WEAR & EROSION Electrical Contacts experience severe erosion from the action of the arc during switching Electric Arcing occurs during most switching operations and is effectively a high current plasma. Effects of individual switching events may be subtle but cumulative effects will still determine switching device reliability and lifetime Contact wear is fundamentally …

MEASURING SKIN Filtering Surfaces for Textural Analysis. Where there exist textures, repeating units or structures it is often illuminating to characterise those units quantitatively. Features could be defects on a machined surface or microstructures designed to encourage turbulence at the microfluidic scale. In this case we have an impression of human skin. Quantifying the structure of …
