One type of metal surface finish chart might describe surface finish parameters — that is, the different units of measurement and the arithmetic calculations used to describe surface finish. A surface finish chart such as this could include the following parameters: Beyond ra why surface finish matters surface measurement selecting the pareto chart of standardized effects surface measurement selecting the surface roughness ra pro chartSurface Finish Destiny ToolSurface Roughness Chart Parison Iso FinishingSurface Finish Destiny ToolSurface Roughness Parison Edm PrecisionSurface Roughness Conversion Chart Tables Ers EdgeWhy Use A Surface Finish Chart The pharmaceutical industry as well as components of a distribution system or conveyor belts, have an established guideline for their surface finish requirements called ASME-BPE.

Surface roughness —also known as surface profile Ra—is a measurement of surface finish -- it is topography at a scale that might be considered "texture" on the surface. Surface roughness is a quantitative calculation of the relative roughness of a linear profile or area, expressed as a single numeric parameter (Ra).
