Reference data, nested contours
When describing a milling contour or hole you specify the reference
plane. The reference plane is the position on which the milling contour
or the hole is created.
 Face (C axis): The Z position (reference dimension)
 Lateral surface (C axis): The X position (reference diameter)
 XY plane (Y axis): The Z position (reference dimension)
 YZ plane (Y axis): The X position (reference diameter)
It is also possible to nest milling contours and holes. Example:
Defining a slot in a rectangular pocket. Holes are drilled inside this slot.
You use the reference plane to specify the positions of these
elements.
ICP supports the selection of the reference plane. The following
reference data are loaded during selection of a reference plane.
 Face: Reference dimension
 Lateral surface: Reference diameter
 XY plane: Reference dimension, spindle angle, limit diameter
 YZ plane: Reference diameter, spindle angle
Selecting a reference plane
Select contour, figure, hole, pattern, single surface or polygon.
Press the Select reference plane soft key. ICP
displays the finished part and, if available, the
contours already defined.
Use the soft keys (see table at right) to select the reference
dimension, reference diameter or existing milling contour as reference
plane.
Confirm the reference plane. ICP loads the values of
the reference plane as reference data.
Complete the reference data and describe the contour, figure, hole,
pattern, single surface or polygon.
