Calculate Surface Roughness (SR)



Formula

The formula to calculate the surface roughness (SR) is:

\[ SR = \frac{Ra + Rz}{2} \]

What is Surface Roughness?

Surface roughness, also known as surface texture, is a measure of the texture and roughness of a given surface. It is a critical aspect in many manufacturing processes and has significant implications on the performance, appearance, and wear resistance of a product or component.

Example Calculation

Consider an example where:

Using the formula to calculate the surface roughness:

\[ SR = \frac{1.5 + 3.0}{2} = 2.25 \]

This means that the surface roughness for this example is 2.25.
