Planer Operations
Depth of Cut
Thickness planing refers to the sizing of lumber to a
desired thickness while creating a level surface parallel
to the opposite side of the board. Board thickness that
the planer will produce is indicated by the scale and
the depth of-cut gauge. Preset the planer to the
desired thickness of the finished workpiece using the
gauge. The depth-of-cut is adjusted by raising or
lowering the planer table (C, Fig. 21) using the
handwheel (F, Fig. 21).
•
The quality of thickness planning depends on the
operator's judgment about the depth of cut.
•
The depth of cut depends on the width, hardness,
dampness, grain direction and grain structure of the
wood.
•
The maximum thickness of wood that can be removed in one pass is 1/8” for planning
operations on workpieces up to 5-
1/2” wide. The workpiece must be positioned away from
the center tab on the roller case to cut 1
/8”.
•
The maximum thickness of wood that can be removed in one pass is 1/16” for planning
operations on workpieces from 5-
1/2” up to 12" wide.
•
For optimum planning performance, the depth of cut should be less than 1/16”.
•
The board should be planed with shallow cuts until the work has a level side. Once a level
surface has been created, flip the lumber and create parallel sides.
•
Plane alternate sides until the desired thickness is obtained. When half of the total cut has
been taken from each side, the board will have a uniform, moisture content and additional
drying will not cause it to warp.
•
The depth of cut should be shallower when the workpiece is wider.
•
When planning hardwood, take light cuts or plane the wood in thin widths.
•
Make a test cut with a test piece and verify the thickness produced.
•
Check the accuracy of the test cut before working on the finished product.
Precautions
•
A thickness planer is a precision woodworking machine and should be used on quality
lumber only.
•
Do not plane dirty boards; dirt and small stones are abrasive and will wear out the blade.
•
Remove nails and staples. Use the planer to cut wood only.
