Tilted working plane
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 (see „Tilting the working plane G16” on page 522).
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 by the section code
LATERAL_Y (see „LATERAL_Y section” on page 52).
The control supports NC program creation with the B axis in DIN PLUS
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)."
The machine tool builder determines the scope of function
and behavior of the B axis. The machine manual provides
further information.
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.
