6.15 Cont
ours in the YZ plane
6.15 Contours in the YZ plane
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 YZ 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 YZ plane
The reference data follows the contour definition with individual
contour elements.
You can find the reference diameter XR with the "select reference
plane" function (see page 418).
ICP generates:
 The section code SURFACE_Y with the reference diameter and
spindle angle. 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.
