Without absolute
position
detector
When
power is
united
ON. the
current
tool
position is
set
to
coordinates
0(0, 0,
0).
In other
words,
the
current
tool
position
is
temporarily
assumed
to
be the coordinate
origin
until the
appropriate
coordinate
system
is
set.
O
In a
slate
where
G92
(reference
coordinate
system)
is
not set. a
work
coordinate
system
is
shifted from the origin of the machine coordinate
system.
O
In a
state
where G92
(reference
coordinate
system)
is
set,
a work coordinate
system
is shifted
from the
origin
of the reference coordinate
system.
Q
If G92 is instructed
in
a
stale
where
a
work coordinate
system
is
set,
the reference coordinate
system
is
set
so
that the
current
tool
position
becomes the coordinate values instructed
by
G92,
and
at
the
same
time the work coordinate
system
is
shifted from the
origin
of
that reference coordinate
system.
@
If work
coordinate
system
cancel
(G52)
is instructed, the work coordinate
system
returns to
the reference coordinate or machine
coordinate
system.
The
same applies when
the local
coordinate
system
is
canceled.
