3D Metrology Surface Roughness Measurement

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 surface 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.

The surface roughness testing lab at EDM Intelligent Solutions offers both contract inspection and on-demand measurement services to support OEM customers and manufacturing service providers within the major Aerospace, Automotive, Communications, Defense, Medical and Scientific industries.

Profile Roughness

3D METROLOGY PROFILE ROUGHNESS MEASUREMENT

Profile roughness measurements allow for measurement of both roughness and waviness along an extracted profile to measure roughness values including Ra, Rq, Rz, and many others.

Area Roughness

3D METROLOGY AREA ROUGHNESS MEASUREMENT

Area-based roughness measurements characterize the surface texture of an entire area through the use of surface texture parameters (Sa, Sq, Sz) and bearing area curve parameters (Sk, Spk, Svk).

Form Removal

3D METROLOGY FORM REMOVAL

Through the use of advanced form removal algorithms, roughness parameters can be extracted on complex surfaces including radii, threads, spherical surfaces, and other surfaces with underlying form. This technology allows EDM 3D Metrology Services to measure roughness on complex parts that are otherwise not measurable using traditional surface roughness inspection equipment.

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.
