DEFINITIONS O F JOINTING AND PLANING
O P E R ATIONS
Jointing Operations - Jointing cuts or edge jointing is the simplest and most common operation which can be done on
the jointer and these cuts are made to square an edge of a workpiece. The fence is square with the table and the depth
of cut is approximately 1/8 inch. The workpiece is positioned on the jointer with the narrow edge of the workpiece on the
infeed table and the major flat surface of the workpiece against the fence, as shown in Fig. 2. The workpiece is moved
from the infeed table, across the cutterhead to the outfeed table. The hand over the outfeed table presses the work down
so that the newly-formed surface will make perfect contact with the table. The hand over the infeed table (usually the
right hand) exerts no downward pressure, but simply advances the work to the cutterhead. Both hands exert pressure
to keep the work in contact with the fence.
Planing Operations - Planing or surfacing are identical to the jointing operation except for the position of the workpiece.
For planing, the major flat surface of the workpiece is placed on the infeed table of the jointer with the narrow edge of the
workpiece against the fence, as shown in Fig. 3. The workpiece is moved from the infeed table, across the cutterhead to
the outfeed table establishing a flat surface on the workpiece. Always use push blocks when performing planing operations.
