WebFeb 22, 2024 · When working with surfaces, you don’t need to create a surface finishing chart. You can use an existing chart to tell you how your surface roughness relates to other surfaces. While you will need to measure the surface yourself, you don’t have to know how each measurement relates to each other to create a unique chart. WebWith a contact-type roughness meter, surface roughness is measured by tracing the probe across the surface of the target. In contrast, a laser-based non-contact roughness meter emits a laser beam onto the target and detects the reflected light to measure the roughness. The direction of measurement is the key to successful measurement.
