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 begin and end depths for the Z-axis.
• Enter either the number of passes OR the distance
between each pass. “Pass” refers to the cuts that
are used to machine the pocket to its “End” depth.
• Enter the Z-axis feed rate.
• Enter a start radius and an 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.
As you're pro-
gramming, keep
in mind that
you may
"teach" the
positions for
the center point
and depth.
