RATE OF FEED (Figs. 17 and 17a)
The proper rate of feed depends
on several factors:
the
hardness
and moisture content
of the workpiece,
the depth of cut, and the cutting diameter
of the bit. When you are
cutting shallow
grooves
in soft woods such as pine, you may use a faster rate of feed.
When making deep cuts in hardwoods
such as oak, you should use a slower rate of feed..
FEEDING
TOO FAST
(Fig.
17)
Clean and smooth finished
cuts can only
be achieved
when the cutter bit is rotating
at a relatively
high speed, taking very small
bites, producing
tiny, clean cut chips°
Forcing the feed of the cutter bit forward too
fast slows the RPM of the cutter bit, and the bit
takes bigger bites as it rotates. Bigger bites
mean bigger chips and a rough finish.
This forcing action can also cause the
router motor to overheat.

the
RPMs
can
become

FEEDING
TOO
SLOW
(Fig.
17a)
When you feed the cutter bit too slowly,
the rotating cutter bit does not cut into
new wood fast enough to take a biter
Instead,
it scrapes
away sawdust-like
particles. This scraping
produces
heat,
which can glaze, bum and mar the cut
in the workpiece
and, in extreme cases,
overheat the cutter bit°
When the cutter bit is scraping instead
of cutting,
the router is more difficult to
control as you feed it.
