Surface roughness is an indicator used to measure the degree of surface micro-irregularities, and it is commonly annotated on mechanical drawings with roughness symbols. The types of roughness symbols include surface roughness symbols, roughness codes, and additional descriptions. The following is a detailed introduction to the types of roughness annotations.<\/p>\n
