![]() Where precision surface engineering is required, surface measurement may be a key element of maintaining control of the manufacturing, by monitoring the process to ensure it is within certain specifications. ![]() Maintaining surface finish is critical for manufacturers and engineers to produce consistent and reliable production processes for each product. Ra surface finish provides a simple value for accept or reject decisions. It basically reflects the average height of roughness component irregularities from a mean line. Surface roughness can be measured by a profilometer, a surface profile measurement tool. Simply average the height across the microscopic peaks and valleys. Ra is the arithmetic average of surface heights measured across a surface, Ra surface finish. Surface roughness, or the texture of a surface, is a calculation of the relative roughness of a surface profile using a single numeric parameter Ra. For some applications, roughness may be desired to promote adhesion for cosmetic finish coatings such as painting, powder coating or plating. ![]() In tribology, rough surfaces usually wear more quickly and may have higher friction coefficients than smooth surfaces. Roughness is a good indicator of the performance of a mechanical component, since irregularities on the surface may form nucleation sites for cracks or corrosion. Surface roughness is a component of surface texture and plays an important roll in determining how an object will interact with its environment. Why is Surface Roughness So Important in Manufacturing?
