is a deviation from flatness as a result of stresses and shrinkage from the uneven drying of lumber.
The types of wood warping include:
- bow : a warp along the length of the face
- crook: a warp along the length of the edge
- kink: a localized crook, often due to a knot
- cup: a warp across the width of the face, in which the edges are higher or lower than the center
- twist: a distortion in which the two ends do not lie on the same plane

Although wood warping has been studied for years, the warping control model for manufacturing composite wood hasn't been updated for about 40 years.
The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)
