There are 5 types of veneer slicing method:
1. Half Round Slicing
Half round slicing is a variation on rotary slicing and is sometimes used on smaller logs. The cut angle is similar to plain or flat slicing, provides a similar grain pattern and results in wider leaves.
2. Rotary Slicing
A log is mounted in a lathe and turned against a blade. Thin slices are peeled from the log in an almost continuous role. This method produces a variety of patterns as the blade slices through successive growth rings. The grain pattern is inconsistent making the leaves more difficult to match. Some species, however, are rotary cut, sliced into leaves and sequenced much like plain sliced veneers.
3. Quarter Slicing
As the name implies, the log is sliced into quarters before slicing the veneer. The knife slices through the quartered log at approximately a right angle to the growth rings. The resulting grain pattern is typically straighter in most species. In some species, principally oak, quarter slicing produces a unique "flake" pattern that is created as the knife bisects radial tubules in the log structure called medullary rays.
4. Plain Slicing
Plain sliced or flat sliced veneers are made by sawing the log in half and cutting or slicing the log parallel to the center or cut line. Leaf widths vary by the distance from the center, and are wider than quartered or rift cut veneers. The grain pattern produced is commonly referred to as "cathedral" or "flame shaped".
5. Rift slicing
Rift slicing or cutting is most often used with oak when the "flake" or medullary rays are not desired. This is achieved by slcing the quartered log at an angle to the growth rings. The process involves placing the quartered log in a lathe and adjusting the blade angle to obtain a straight rift grain pattern.
