Material
and
its
relation
to
the
cutting
rate
Fig.
7.1
Description
of
Band
Depending
on
the
hardness
of
the
material
the
cutting
rate
will
increase
or
decrease.
For
example,
it
takes
more
time
to
cut
stainless
steel
than
to
cut
cast
iron.
The
surface
conditions
will
also
affect
the
cutting
rate.
If
there
are
places
on
the
surface
on
the
material
which
are
hard,
a
slower
blade
speed
will
be
required
or
blade
damage
may
result.
It
will
be
slower
to
cut
tubing
than
to
cut
solids,
because
the
blade
must
enter
the
material
twice,
and
because
coolant
will
not
follow
the
blade
as
well.
Tough
or
abrasive
materials
are
much
harder
to
cut
than
their
machinability
rating
would
indicate.
Tooth
spacing
is
determined
by
the
hardness
of
the
material
and
its
thickness
in
cross
section.
Tooth
set
prevents
the
blade
from
binding
in
the
cut.
It
may
be
either
a
"regular
set"
(also
called
a
"raker
set"
)
or
a
"wavy
set".
The
regular
or
raker
set
is
most
common
and
consists
of
a
pattern
of
one
tooth
to
the
left,
one
tooth
to
the
right,
and
one
which
is
straight,
or
unset.
This
type
of
set
is
generally
used
where
the
material
to
be
cut
is
uniform
in
size
and
for
contour
cutting.
Wavy
set
has
groups
of
teeth
set
alternately
to
right
and
left,
forming
a
wave
‐
like
pattern.
This
reduces
the
stress
on
each
individual
tooth,
making
it
suitable
for
cutting
thin
material
or
a
variety
of
materials
where
blade
changing
is
impractical.
Wavy
set
is
often
used
where
tooth
breakage
is
a
problem.

shown
