Fundamentals

Tilted working plane
Refer to your machine manual.
The machine tool builder determines the scope of
function and behavior of this function.
The B axis makes it possible to drill, bore and mill in oblique planes.
To make programming easy, the coordinate system is tilted in
such a way that you can define the drilling patterns and milling
contours in the YZ plane. The actual drilling or milling operation is
then performed in the tilted plane.
Further information:
The separation of contour description and machining also applies to
machining operations in tilted planes. Contour regeneration is not
available.
Contours in tilted planes are identified with the section code
SURFACE Y.
Further information:
The control supports NC program creation with the B axis in
ISO Mode and smart.Turn.
The graphical simulation shows the machining operation in a tilted
working plane in the familiar lathe and front windows, as well as in
the side view (YZ).
If you are using a tool with an angled tool holder you
can also use the tilted working plane without the B axis.
Define the angle for the tool holder as Angular offset
RW in the tool description.
