The WAVINESS calculation analyzes the maximum peak-to-valley range of deviations within a given curve length over the entire section. The CVWAVINESS, CCWAVINESS, LEWAVINESS, and TEWAVINESS calculations are similar, but they are over the convex, concave, leading edge, and trailing edge curve, respectively, instead of over the entire section.
You specify which best-fit to use to calculate the waviness, which defines the deviations used for calculating deviations. Then, the peak-to-valley range of deviations is computed several times, once for each possible position of a sliding window of curve length WAVEWIDTH (see "Wave Width"). For each window position, the maximum signed deviation minus the minimum signed deviation defines the form over the window. The final waviness is reported as the largest of the window form values.
The following example shows a graphic depiction of the WAVINESS calculation.
