Interactive Bandpass Filtering

Many surfaces are dominated by a repeating, pattern or shape in their texture. Sometimes this texture is desired, as on a gripping surface. Other times it is something we try to avoid, such as “orange peel” in paint, or chatter in a bearing raceway. In each of these cases it is helpful to isolate the

Can a Stylus Really Measure This Surface?

For many critical applications, companies are finding it necessary to not just assess the geometric aspects of the surface, but also the quality of the surface. You’ll find specifications with terms such as “torn and folded material,” “porosity,” “pull-outs,” “micro-burrs” and “micro-ledges.” The surface in the image above is marked by torn and folded material

Measuring Arcs with Stylus Instruments - Digital Metrology Solutions

Measuring arcs with stylus instruments

Many critical surfaces are comprised of arcs or arc-like geometries. Measuring these surfaces with many traditional stylus-based instruments poses fundamental challenges. In this post we look at several considerations that may affect your ability to properly measure arcs and understand your curved surfaces.

Digital Metrology-Standard surface texture parameters can't always discern whether a mating surface will seal or leak

Will your sealing surfaces leak?

Most engineers specify only basic height-based parameters, such as average roughness or total flatness, in sealing applications. The challenge is that “sealing” is not measurable purely in units of height. Learn how advanced surface texture analysis can be used to predict whether a surface will seal or leak.
