Spiral
A spiral is a winding and gradually widening curve or coil.
Spirals are defined by their center point, beginning and end-
ing radii, and sweep angle.
The center point is the (X, Y) coordinate at the core of the
spiral. The beginning radius is the distance from the spiral's
center point to its starting point, and the ending radius is the
distance from the spiral's center point to its ending point.
To program a spiral:
•
From the PGM screen, press the
MORE STEPS
softkey.
•
Press the
MORE STEPS
softkey two more times.
•
Press the
SPIRAL
softkey.
•
Enter the spiral's center point.
•
Enter the depth.
•
Enter a start and end radius (measured from the
center point). If the ending radius is less than the start
radius, then the tool will cut from the outside in, or
vice versa.
•
Select the direction by pressing the
CW
softkey for a
clockwise direction or the
CCW
softkey for a counter-
clockwise direction.
• Enter the sweep angle (e.g., 180 for a half-rotation; 360
for one rotation; 1080 for three rotations, etc.).
• Using the softkeys, choose a tool offset—
LEFT
,
CENTER
,
RIGHT
,
INSIDE
or
OUTSIDE
.
• Enter a feed rate.
As you are pro-
gramming, keep
in mind that
you may
"teach" the
positions for
the center point
and depth.
Use the calcula-
tor keys to let
MILLPWR factor
the angles for
you. For exam-
ple, enter "3.5 x
360" to create a
spiral with three
and a half rota-
tions.
