Types
of
Coordinate
Systems
(G54
to
G59
G92)
There
are
five
types
of
coordinate
systems
as
shown
below.
(1)
Reference
coordinate
system
This
is
a
basic
coordinate
system
set
by

or
automatic
coordinate
setting.
Until
any
of
these
operations
is
performed
after
power-on.
the
power-on
position
is
temporarily
assumed
to
be
the coordinate
origin.
(2)
Work
coordinate
system
&
This
coordinate
system
is
set
by
any
command
from
G54
to
G59.
It
is
shifted
from
the
reference
coordinate
system
by
a
value
set
for
that
G
code
from
work
coordinate
system
software
screen.
Up
to
six
work
coordinate
systems
can
be
used.
(3)
Local coordinate
system
&
A
coordinate
system
shifted
from
the
given
work
coordinate
system
can
be
used
by instructing
G52
Q2.
The local coordinate
system
is
only
valid
when
a
work
coordinate
system
is
set.
(4)
Machine
coordinate
system
This
coordinate
system
is inherent
to
the
machine
determined
by
performing
reference
return,
and
is
created
on
the
reference
point
(0,
0,
0).
If
no
coordinate
setting
is
made
after
power-on,
the
power-on
position
is
temporarily
assumed
to
be
the
origin
of
the
reference
coordinate
system.
