Roughness is a measure to determine the texture of the surface and it is determined by determining the amount of vertical changes on the surface compared to the actual smooth surface. If these changes are large, it has a rough surface, and if it is small, it is soft. Roughness plays an important role in determining the mutual effect of surfaces and by knowing it, many behaviors of mechanical components can be predicted. In the usual equipment for roughness measurement, which is known as roughness tester or roughness tester, contact method is used and a needle-like head moved on the surface according to the number of oscillations and maximum displacement can determine the surface roughness.
