If you have not read "9 Basic Steps to Reading Welding Symbols" it may be worth taking a look before continuing with this post. The "9 Basic Steps to Reading Welding Symbols" focuses on fillet welds, but goes thru the basics of the welding symbol (arrow, reference .
Surface Roughness symbol in drawing Surface roughness symbol is given to convey manufacturing process related information only. Unless written specifically on the symbol, they do not carry the surface texture type ( plated / milled / cold drawn). These symbols are given irrespective of material and its surface condition.

Surface roughness is usually specified with a "check mark" symbol on a drawing as shown in the figure below. Surface roughness is typically indicated in RMS or microinches (µin) and is located on the left side of the symbol above the check mark. In the example below the roughness value is 32 RMS maximum and 16 RMS minimum.
Substituting Variable Values in Program Understand how real numbers and integers are treated by the CNC control Real numbers are any number rational or irrational Real numbers include integers, .3765, 5, 10 are all real numbers Integers are whole numbers 2500, 3, 20 Numbers with decimals are not integers Some NC words only allow integers
Nov 03, 2008· What Do Multiple Triangle Symbols in Surface texture notes mean? Q. Surface texture symbol I notice one to four triangles defining a surface finish. Can you tell me what this means expressed in micro inches, number or microns. Thanks, Sheldon Epstein
The above symbol indicates that the removal of material by turning is required to achieve an Ra value of µm and an Rz value of µm when measured using a cut off and lower cut of value of with Gaussian filtering. The maximum amount of material removal allowed to achieve the required finish would be 3mm.

The principal ISO standard that specifies syrface roughness is ISO 1302 and defines the surface roughness symbology and additional requirements for engineering drawings. The details in ISO surface finish standards relate to surfaces produced by abrading, casting, coating, cutting, etching, plastic deformation, sintering, wear, erosion, and some other methods.
Surface finish, also known as surface texture or surface topography, is the nature of a surface as defined by the three characteristics of lay, surface roughness, and waviness. It comprises the small, local deviations of a surface from the perfectly flat ideal (a true plane).. Surface texture is one of the important factors that control friction and transfer layer formation during sliding.
