WebIn measurement of roughness, surface profiles are taken with a lateral sampling interval of 0.125 m, typically over an evaluation length of 4 mm. Three parameters of the instrumentation are important in the specification of roughness measurements. WebThe same electroforming process used to produce the Surface Roughness Scale is available from GAR Electroforming to serve your products needs. The surfaces used in this scale are reproductions of accurately machined surfaces measured in microinches (millions of an inch - 0.000001"). The numbers engraved alongside each surface are the average ...
