WebRoughness depth. DIN EN ISO 4287, ASME B46.1. Single roughness depth R. zi. is the vertical distance between the highest peak and the deepest valley within a sampling length. Mean roughness depth R. z. is the arithmetic mean value of the single roughness depths . R. zi. of consecutive sampling lengths: The R. z. definition is identical to the ... WebAug 20, 2024 · Typically, surface finishes in the range of 32 microinches Ra to as low as 4.0 microinches Ra and better are the numbers needed to be achieved. Comparatively, a traditional milling or turning operation might achieve a finish of about 125 microinches to 32 microinches Ra.

Since this profile was made in the direction of the Y axis, the parameters are specifically called: Stylus (Y) Rk, the Core Roughness Along Y Stylus (Y) Rpk, the Reduced Peak Height Along Y WebRpk (peaks), Rk (core roughness), Rvk (valley depth).
