2.5 FEED FUNCTIONS
2.5.1 Rapid Traverse Rate
The
rapid
traverse
motion is used for the motion for Positioning (GOO) and
for the motion for Manual Rapid Traverse (RAPID).
This
rapid
traverse rate
is specified by
the machine tool builder, and
set to
each
axis
as a parameter.
(1)
Setting
range
For each
axis, rapid traverse
rates
can
be
set at
some suitable
multiple
of 1mm/ min
(or deg/ min).
The maximum
programmable rapid
traverse rate
is 240,000mm/' min.
I
Machine tools have their own
optimum rapid traverse
rates.
Refer
to
the manual provided by the machine tool builder.
(2) Motion
path
Motion paths are normally
not
straight because the end
points of each
of the axes
are
reached
at
different times by independent axis
motion.
(3)
Override
For override rapid
traverse rates,
Fo, 25%, 50% and 100% of the basic
rapid traverse
rates,
are
available. Fo is
a constant
feedrate
set
by
a
parameter (Pm2447).
