Surface Finish Symbols
Machinist also refers to surface roughness as surface finish. So what is Surface texture? Surface texture measures a surface's overall texture, defined by the surface's lay, surface roughness, and waviness. This graphic illustrates how to think about the link between Waviness, Lay, and Roughness: Surface texture characteristics What is Roughness?
Surface Finish Symbols Get It Made
A surface finish symbol is a mark found on pieces that have been machined by either turning, grinding, or boring. Surface finish symbols are not the same across all industries.
Surface finish
1. As Machined As-machined parts are just off the production line and contain light tool marks, an average amount of surface abrasion, and a particular texture or completed appearance. According to the use case, a component's average surface roughness (Ra) is the difference between its real and ideal machining surface roughness.

It is a means of altering material surfaces through processes involving adding, removing, or reshaping the metal surface. Three (3) major characteristics can define the surface finish. They are surface roughness, waviness, and lay. The measure of the total space irregularities on the surface metal is known as Surface Roughness.

A symbol for defining the surface finish of a part. There are many variations of the surface texture symbol but most often it is used with a microinch or micrometer value callout that specifies the roughness of a surface.

Surface Finish is a measure of the overall texture of a surface that is characterized by the lay, surface roughness, and waviness of the surface. Surface Finish when it is intended to include all three characteristics is often called Surface Texture to avoid confusion, since machinists often refer to Surface Roughness as Surface Finish.

Definition and Importance of Surface Finish The surface finish is more than just a smooth touch or shiny look. It encompasses the texture of a surface, its roughness, waviness, and lay. These factors are not just for show; they play a pivotal role in determining the quality and functionality of machined parts.
What is Surface Finish? Units, Symbols & Chart
Surface finish is composed of three distinct elements - roughness, lay, and waviness (See Figure 1 below). However, it is not uncommon in machine shops for the term surface finish to be used to describe only surface roughness.
Surface Finish Lay Symbols
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.

Whenever machinists talk about "surface finish," they often refer to surface roughness. Waviness refers to the warped surface whose spacing is greater than that of surface roughness length. Lay refers to the direction the predominant surface pattern takes. Machinists often determine the lay by the methods used for the surface.
