Surface Finish A Machinist s Tool. A Design Necessity
Surface Finish A Machinist s Tool. A Design Necessity. In operation this surface has sufficient area to promote piston compression with enough pockets to hold lubricating oil. The Ra parameter measures average roughness. It is not sensitive to occasional spikes and gouges. On the other hand the Rmax parameter is designed to detect these

in the contact and surface finish of the product (Schey 1983a and 1983b). Figure 4.1(a) illustrates schematically the inlet to the bite during a strip rolling operation. Neglecting for the moment the surface roughness on the roll and strip a smooth film thickness hs at the end of the inlet can be determined by integrating Reynold s equation.
