COORDINATE SYSTEM
2.7.1 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 G29, 1
ZERO SET] key.
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.
