Microns ra
WebApr 22, 2024 · When measuring in a parallel direction, the average surface finish was 3.3 microns Ra before grinding and 0.21 microns Ra after grinding (Figure 7). When measuring perpendicular to the grind direction the surface finish was an average of 2.1 microns Ra before grinding, and as low as 0.5 microns Ra after grinding (Figure 8). WebJan 1, 2009 · RA is defined as the arithmetic average deviation of the surface valleys and peaks and is usually used to describe the roughness of a machined surface. It is identical to the I.S.O. measurement known as center line average, or CLA, and is also equal to the arithmetic average mentioned a moment ago.

WebSurface roughness, often shortened to roughness, is a component of surface finish (surface texture). It is quantified by the deviations in the direction of the normal vector of a real surface from its ideal form. If these deviations are large, the surface is rough; if they are small, the surface is smooth.
