*
When
a
radius and
angle
are
specified,
this
function
performs
positioning
by converting
the data
into
rectangular
coordinates.
This
function
is
used
with
canned
cycles
(G81
to
G89,
G73,
G74,
G76,
G
77).
“Bolt
hole
circle,”
“arc,"and
“line
at
angle”can
be
implemented.
The
tool
is
moved
to
the coordinate
position
calculated
from
the radius and
angle
at
rapid
feedrate
(GOO).
(1)
Bolt
hole circle
(G70)
command
The tool is
positioned
at
a
point
on a
circle
drawn around coordinates
specified
by
X
and
Y
at
radius
I,
equally
divided
by
L,
starting
from
a
point
at
angle
J
against
X-axis
ori
that circle.

Used
to
define
the
center
position
of
the bolt
hole
circle. The
center
is
defined
according
to
G90/G91.
Used
to
set
the radius
of
the bolt hole circle.
It
must
be
set
with
a
positive
number. The unit
can
be
set
with
the minimum
unit
of
setting.
Used
to set
the
angle
of
the
point
that
is
positioned
first.
It
is
given
in
units
of
0.001
degree,
with
the
counterclockwise
direction
assumed
to
be
positive.
Used
to
set
the number
by
which the circle is divided.
If
positive, positioned
counterclockwise;
if
negative,
positioned
clockwise.
