Problem Possible Cause Possible Solution
Workpiece came out
twisted.
Improper feeding. Use outfeed table as reference point for feeding.
Apply even pressure and feed rate on the entire
workpiece.
Outfeed table is not in
parallel with the
cutterhead.
Ensure outfeed table is in parallel with
cutterhead, and outfeed/infeed table are
coplanar.
More passes needed. Significantly twisted board takes multiple passes
to flatten.
Excessive snipe Outfeed table too low. Adjust outfeed table to ensure it is flush with the
cutting arc of the cutterhead.
Too much downward
pressure when feeding
the end of workpiece.
Once the workpiece reaches the outfeed table,
use outfeed table as reference. Reduce feeding
pressure apply to the workpiece that is still on
the infeed table.
Chipping Too much material
removed in one pass.
Reduce feed rate / depth of cut.
Planing across/end
grain.
Do not use a jointer to cut across/end grain.
Damaged cutter. Rotate/replace cutter insert.
Cutting against grain; or
knots.
Avoid processing workpiece with knots. Cut
WITH grain whenever possible. When jointing
workpiece with complicated grain pattern,
reduce depth of cut. Sometime moistening
problematic areas can reduce chipping.
Fuzzy looking finish. Wood moisture content
too high.
Only process wood with less than 20% moisture
content.
Dull cutter. Rotate/replace cutter insert.
Some wood types tend
to have fuzzy grain.
Adjust feed rate / depth of cut.
Use sharp cutters.
Glossy looking finish. Dull cutter. Rotate/replace cutter insert.
Cutting depth too
shallow.
Increase depth of cut.
Long line or ridges
running along the
length of board.
Chipped cutter. Rotate/replace cutter insert.
Finished stock has
uneven front-to-back
thickness.
Cutterhead is not flush
with outfeed table.
Adjust outfeed table to ensure it is flush with the
cutting arc of the cutterhead.
Inconsistent feeding
pressure applied to
workpiece.
Apply even feeding pressure on workpiece. Keep
feed rate consistent.
Finished stock is
concave/convex in
the middle.
Infeed/outfeed table
are not coplanar.
Ensure outfeed table is parallel with cutterhead,
and outfeed/infeed table are coplanar.
