Understanding surface roughness symbols. Symbols that indicate the surface texture of machined and structural parts are used in industrial diagrams. The pictorial representation using these symbols is defined in ISO 1302:2002. This section will explain how to write these symbols to indicate surface textures. Terminology explanation
Lapping - Wikipedia. Lapping is a machining process in which two surfaces are rubbed together with an abrasive between them, by hand movement or using a machine.. This can take two forms. The first type of lapping (traditionally called grinding), involves rubbing a brittle material such as glass against a surface such as iron or glass itself ...
Define Lapping: The term "lapping" is used to describe a number of various surface finishing operations where loose abrasive powders are used as the grinding agent at normally low speeds. It is a process reserved for products that demand very tight tolerances of flatness, parallelism, thickness or finish.

Lapping is a controlled sanding or polishing process that creates an accurate finish on a part. The result is a precise roughness on flat or domed surfaces. Flat lapping can correct surface irregularities caused by sawing or grinding. Domed lapping produces a slender, uniform shape for lenses and other curved surfaces.
A high-grade machine finish, which needs close control. It is relatively easy to produce with cylindrical, centerless, or surface grinders. It is also preferred for products that do not require continuous motion or large loads. 0.4: 16: High-quality surface are often produced using emery buffing, lapping, or coarse honing.

Grinding, reaming, honing, lapping, etc. are classified as surface finishing processes. Such processes offer low material removal rate (MRR) but high accuracy, close tolerance and better finish. Conventional machining (also known as metal cutting) processes utilize a sharp-edged wedge shaped cutting tool to compress and shear off material from ...
Grit size and Surface Finish. As an example, on a steel part hardened to 60 HRc, lapped using silicon carbide 500 grit, a pressure of 250 g/cm squared will produce a surface finish of about Ra= 0.2 my (N4) or Rz 0.6-0.8, whereas by reducing the pressure to 50 g/cm squared, a surface finish of about Ra= 0.05 my (N2) or Rz 0.2-0.3 can be obtained.

Surface finish is a term that refers to the process used to alter a metal's surface by adding, removing or reshaping. The goal is to protect the metal and improve the aesthetic side. The result depends on the metal finishing method. Often, there are a few different ways to achieve the same or similar results.
