Kerf

A series of grooves, or kerfs, cut down to about two-thirds of the thickness of the wooden piece, so that it can be bent around curves.

kerf

1. In a suspended acoustical ceiling, a groove cut into the edges of an acoustical tile to receive splines or supporting members of the ceiling suspension system.
2. A slot or cut made in a material such as wood or metal.

And instead of a kerfed lining, a much stiffer continuous laminated lining is used for bonding to the edge of the soundboard.
A laminated lining, for instance, is far superior to a kerfed lining; it is much stiffer and reduces the high compressive stress in the soundboard due to the string loads.
The number of logs for each end diameter range and the preprocessed dimensions of the center-bored and kerfed specimens are shown in Table 1.
Within each cross section and size group, 6 timbers served as nontreated controls, 9 were kerfed, and 6 were cut into 2 each of 500 mm length and prepared as center-bored specimens.
As would be anticipated, after being kiln-dried for 168 hours using the first kiln schedule (Table 3) the final MC values for the center-bored specimens were substantially lower than those for the solid or kerfed square or round larch timbers (Table 5).
To evaluate differences and confirm results from previous research, 120 specimens as described in PS 1-95 were cut from a single 3-ply, 3-layer, 3/8-inch-thick Douglas-fir (Pseudotsuga menziesii) plywood panel and kerfed accordingly to produce 60 open and 60 closed samples.
Kerfed tapered specimens were positioned into the machine such that the kerf ran along the top (relative to load head) edge of the specimen directly beneath the load head.
As previously noted, approximately one-half of the tapered bending specimens were kerfed for the purpose of minimizing checking.
long and kerfed one third of the length of the specimen from each end were cut following the PS-5 standard (3,4).
Checking in kerfed and center-bored ACQ-treated posts was compared with that occurring in unmodified ACQ-treated radiata and slash pine posts, which acted as controls.
Results here for kerfed radiata and slash pine posts treated with ACQ and exposed outdoors in the dry temperate climate of Canberra, Australia, confirm previous findings.
