Surface Roughness Symbols: ISO Finishing

Surfaces of parts come in a wide variety from shiny and smooth to rough and matte—they are not machined that way. During the design process, surface roughness symbols indicate what is required and efficiencies can be made during the machining process. That said, irregular textures can still be created as a result of the die or cutting tool
