ABSTRACT
The term “roughness” is used to describe the extent to which a surface deviates from being perfectly flat in a normal direction. While it is possible to make a surface as smooth as possible, the roughness value will never be able to be decreased to zero. Surface finishing is the process of smoothing out a product’s exterior. Surface finishing of components is currently a crucial industry requirement for their precise operational functionality (Balogun & Mativenga, 2017). Some industrial products require surface finishing just for having the good appearance or aesthetic look. However, many industrial products need a finished surface with good surface characteristics in order to achieve benefits, such as dimensional precision, near resistance fit or shape, improved tool life, and lower wear and frictional losses, among other things (Mohanty et al., 2013). Various industries like electronics, optics, automotive, and avionics require specific surface characteristics of micro products and components for their precise operational requirements (Rjurkar et al., 2006). However, it can be challenging to give industrial components’ surfaces the necessary precise surface finish. In the manufacturing industry, finishing components that need higher precision is a complex and time-consuming job (Pattnaik et al., 2012). Almost 10% to 15% of the total production cost of a component is expended for its precise surface finishing (Verma et al., 2017).
