Filtering for Roughness and Waviness

This animation is based on some of Digital Metrology’s training materials and shows how the roughness and waviness profiles change with a changing filter cutoff.

The profile is from a milled surface with a 2.5 mm feed rate.

  • The top left graph shows the primary & waviness profiles.
  • The top right shows the wavelength content and the filter transmission curves
  • The bottom graphs show roughness (left) and waviness (right).
