HIGH-RESOLUTION 3D METROLOGY SURFACE ROUGHNESS MEASUREMENT COMPANY
In addition to our Form and Difference Measurement solutions, we offer non-contact, high-resolution profile and area-based roughness measurement of surfaces down to 1.2 µinches. Our 3D surface profiler technology is capable of measuring the surface roughness, surface finish, surface profile, and surface texture of almost any material, including metals, ceramics, and plastics.
What is Surface Roughness?
Surface roughness itself is defined as the frequency of peaks and valleys in the base material of a surface. In machined parts, the surfaces are composed of complex shapes made of a series of peaks and valleys of widely varying heights, depths, and spacing. The surface roughness is affected by the asperities of that surface. Surface roughness is a critical, yet often overlooked, aspect of any manufacturing project.
What is Surface Roughness Measurement?
Surface Roughness Measurement both characterizes and quantifies a surface. Surface finish callouts are typically listed as requirements on engineering drawings along with the other dimensions and tolerances of a part. These surface roughness measurement values are calculated using the 3D surface profilometer and are expressed as a single numeric parameter, Ra, if the calculation involves calculating the roughness of a part’s linear profile or Sa if it involves the roughness of a parts full surface area.
