finishing symbols grinding and machining

Specification of grinding wheel: Grinding wheel is the main component of the grinding machine. It is responsible for the whole machining process. The proper selection of grinding wheel is very important and the selection of the grinding wheel depends on various factors such as a material of the work piece, finishing requirements etc...Surface finish refers to the process of altering a metal's surface that involves removing, adding, or reshaping. It is a measure of the complete texture of a product's surface that is defined by three characteristics of surface roughness, waviness, and lay. The surface roughness is the measure of the total spaced irregularities on the surface.

Additional surface finishing passes typically take place afterward — in particular, a "spark-out" pass relieves some of the stress on the machine tool and uses plowing to impart a better surface finish and size tolerance. Precision grinding is a middle-ground between metal removal and part size control, and serves as the basis for creep ...Understanding surface roughness symbols.

Advent of advanced grinding machines and grinding wheels has elevated the status of grinding to abrasive machining where high accuracy and surface finish as well as high material removal rate can be achieved even on an unhardened material. The bulk grinding wheel – workpiece interaction as given in Figure 2 can be divided into the following...Grinding uses fixed abrasives—the abrasive particles are bonded to the paper or platen—for fast stock removal. Polishing uses free abrasives on a cloth; that is, the abrasive particles are suspended in a lubricant and can roll or slide across the cloth and specimen. A book edited by Marinescu et
