Figure 3 – Average Roughness (Ra)To calculate Rz, the roughness profile is divided into five equal lengths. The height difference between the highest and lowest point in each of the five sections is known as the total roughness, or Rt, for that section. Rz is the average of the five Rt values. The calculated Rz value is approximately the height of the …
