Rotation
of work coordinate
system
&
(1)
By setting an angle
of rotation when
a
work coordinate
system
is
set
by G54
to
G59
command, it is possible
to rotate
the coordinate
system
simultaneously
with its
movement.

At the
same
time the work coordinate
system
is shifted by G54,
the coordinate
system
is rotated by
a
quantity
of R around the
point
(0,

of that work coordinate
system.

A work coordinate
system
shifted by G54 and then rotated is
canceled
and
a
new
coordinate
system
is created by using the
G55 work coordinate
system
shift quantity and
angle
of
rotation.
(G69)
Return
to
the coordinate
system
of
G92
by
G52. At this
time,
rotation is also canceled.
