On the X–C plane coordinate system, a figure is specified having an
X–coordinate which is a diameter and a C–coordinate which is a radius:
C–axis (hypothetical axis)

(1) Figure data programming screen for the approach
START PNT X COORD (X): X–coordinate of the notch start point
(diameter)
START PNT C COORD (C): C–coordinate of the notch start point
(radius)
APPROACH DIRECTION (P): Direction of rotation along the
approach arc
Use the [ ] or [ ] soft key to
select the direction.
APPROACH RADIUS (R): Radius of arc during approach
(2) Contour selection and figure data input
Enter the figure data for approaching and press the [INSERT] soft
key. Then, the following contour menu is displayed in the soft key
field.
