iTNC 530 - TNC 640 - DR. JOHANNES HEIDENHAIN GmbH

Machining with Five Axes
– Swivel Head and Rotary Table Controlled by iTNC
Many fi ve-axis operations that at fi rst
glance may seem very complex can be
reduced to conventional 2-D movements
that are simply tilted about one or more
rotary axes or wrapped onto a cylindrical
surface. The iTNC supports you with
application-oriented functions to help you
write and edit such programs quickly and
simply without a CAM system.

Tilting the working plane*
Programs for contours and holes on
inclined surfaces are often very complex
and require time-consuming computing
and programming work. Here the iTNC 530
helps you to save a great deal of
programming time.
You program the part as usual in the
working plane (e.g. the X/Y plane), but it is
machined in a plane that is rotated in one
or more axes about the main plane.
The PLANE feature makes it easy to defi ne
a tilted working plane: You can specify tilted
working planes in seven different ways,
depending on the information on the
workpiece drawing. In order to keep the
use of these complex functions as simple
as possible, a separate animation is
available for each possible plane defi nition,
so that you can view them before selecting
the function. Clearly arranged support
graphics assist you during input.
You can defi ne the positioning behavior
with the PLANE function so that there are
no unpleasant surprises when the program
is run. The settings for defi ning the
positioning behavior are identical for all
PLANE functions, making everything that
much easier.
* The machine and the iTNC must be adapted to these
functions by the machine tool builder.
