COORDINATE SYSTEM (Cont'd)

Rotation of work coordinate
system
$•
The coordinate
system
can be rotated by
a set angle
around the
origin
(0,
0,
0)
of the work coordinate
system.
Setting reference
coordinate
system by
G92
Coordinate
systems must
be
set
before move commands
can
be
programmed. Once
a
coordinate
system
is
set,
one absolute
coordinate
system
is
determined, so
that all
subsequently
issued absolute
move
commands
are
moved
along
the
set
coordinate
system.

G92 is a G code
of the
non-modal
group
that is
only
effective in the
instructed blocks. No other G codes
nor
the
F,M,S,T, or
-SB codes
can
be instructed in the same block.
