Since 1994 Michigan Metrology has been providing high-volume inspection services and solving problems related to surface roughness, wear, texture, finish, flatness and more. Using advanced 3D surface roughness measurement and analysis techniques, state-of-the-art equipment and expert understanding of 3D surface metrology we have helped thousands of customers.
SQUEAKS
Average Roughness, measured by Sa or Ra, may meet specs, yet a brake system may still make noise. In some cases squeaks like these have been related to 3D surface roughness measurement parameters such as amplitude symmetry (Ssk, Spk/Sk) and surface slope (Sdq).
