5.13 Lateral surface contours in
smart.Turn
In smart.Turn, ICP provides the following contours for machining with
the C axis:
 Complex contours defined with individual contour elements
 Figures
 Holes
 Pattern of figures or holes
Reference data of lateral surface
The reference data is followed by the contour definition with individual
contour elements: See "Contour elements on lateral surface" on
page 404.
You can find the reference diameter XR with the "select reference
plane" function (see page 411). The reference diameter is used for
converting angle dimensions into linear dimensions.
ICP generates:
 The SURFACE section code with the reference dimension
parameter. In nested contours, ICP generates only one section
code.
 A G308 with the parameters contour name and milling depth.
 A G309 at the end of the contour description or after the figure.
