WebThe 3D surface finishing milling by ball-end milling cutter is one of the most often used machining technologies. In case of ball-end milling the surface roughness can be described... WebApr 3, 2011 · Traditionally, the sealing industry has used three parameters—Ra, Rmax and Rz (Figure 1)—to measure surface finish and define sealing technology requirements. While easy to measure, and based on industry standards, these traditional parameters are not enough to accurately evaluate surface quality for the following reasons.
