Surface Roughness Ra, Rz, Ry
2022.10.28
Ra-- in the sampling length L within the outline of the arithmetic mean of the absolute value of the offset Rz-- within the sampling length and average value of the five largest profile peak height and the average of the five largest outline of a deep valley. Ry-- between sampling length L within peak contour lines and contour line from the bottom.

When the ultrasonic probe is translated, the waveform is relatively stable. When detecting on both sides, the reflected wave amplitude is different, and sometimes it can only be detected from one side.
