In smart.Turn, ICP provides the following contours for machining with
the Y axis:
 Complex contours defined with individual contour elements
 Figures
 Holes
 Pattern of figures or holes
 Single surface
 Polygon
Enter the dimensions of the XY plane contour elements in Cartesian
or polar values. You can switch between them by pressing a soft key
(see table). You can mix Cartesian coordinates and polar coordinates
to define a point.
Reference data in XY plane
The reference data follows the contour definition with individual
contour elements.
You can find the reference dimension ZR and the limit diameter IR
with the "select reference plane" function (see page 418).
ICP generates:
 The section code FRONT_Y with the parameters reference
dimension, spindle angle, and limit diameter. The section code is
omitted for nested contours.
 A G308 with the parameters contour name and milling depth.
 A G309 at the end of the contour description.
