6.10 Contour elements on lateral
surface
With the "contour elements of a lateral surface" you can create
complex milling contours.
 Cycle mode: Contour for radial ICP milling cycles
 smart.Turn: Contour for machining with the C axis
Enter the dimensions of the lateral surface contour elements in
Cartesian or polar values. You can use the linear dimension as an
alternative to the angular dimension. You can switch between them by
pressing a soft key (see table).
Starting point of lateral surface contour
Enter the coordinates for the starting point and target point in the first
contour element of the contour. Entering the starting point is only
possible in the first contour element. In subsequent contour elements,
the starting point results from the previous contour element in each
case.
Press the Contour menu key.
Press the Insert element soft key.
Specify the starting point.
Soft keys for polar coordinates
Switches the field from linear
dimensions to entry of the angle C.
Switches the field to entering the
polar dimension P.
The linear dimension is essentially the unrolled surface at
the reference diameter.
 For lateral surface contours, the reference diameter is
specified in the cycle. The linear dimensions of all
subsequent contour elements are referenced to this
diameter.
 When called from smart.Turn, the reference diameter in
the reference data is requested.
Parameters for defining the starting point
ZS
Starting point of contour
CYS Starting point of the contour as linear dimension
(reference: diameter XS)
P Polar starting point of contour
C Polar starting point of contour (angle)
