This requires an aggressive roughing operation that generates deep scratches, followed by a finishing operation that removes … WebThe reduced groove depth Rvk characterizes the proportion of the profile depths that extend into the material from the core profile. In the case of forged functional surfaces, e.g., for cylinder liners, a high Rvk value is desirable in order to enable absorption of lubricant with an otherwise plateau-like structure.

WebValley Depth, Rvk*, is the distance between the intersection line of the surface ratio Mr2 and the deepest valley. Retention Volume, Vo, is the area between the material ratio curve and the 100% material line below the core roughness.
