Machining with Five Axes
– The iTNC 530 Permits Optimum Tool Movement
Modern machines often work with four or
fi ve positioning axes. This makes it possible
to machine complex 3-D contours. The
required programs are usually created on
external CAM systems and comprise a
large number of very short line segments
that are transferred to the control. Whether
the workpiece is actually machined
according the program’s instructions
depends essentially on the geometric
behavior of the control. With its optimized
path control, its precalculation of the
contour and its algorithms for jerk
limitation, the iTNC 530 has the right
functions for a perfect surface in the
shortest possible machining time. See for
yourself. In the end, it’s the quality of the
workpiece that proves the performance of
the control.

3-D contour machining at its fi nest
The iTNC 530’s short block processing
time of only 0.5 ms for a 3-D line segment
without tool compensation permits high
traversing speeds even on complex
contours. This enables you, for example,
to mill molds or dies approximated with
0.2 mm line segments at feed rates as
high as 24 meters per minute.
The particularly jerk-free path control
when machining 3-D fi gures and the
defi ned rounding of series of straight-line
segments provide you with smoother
surfaces as well as high dimensional
accuracy.
The iTNC 530 thinks ahead. Its “lookahead”
function anticipates future changes
in direction by adjusting the traversing
speed to the programmed surface. If
desired, it also enables the iTNC 530 to
reduce the feed rate when plunging the
tool into the workpiece. This lets you
simply program the maximum machining
speed as the feed rate. The iTNC 530
automatically adapts the actual speed of
the workpiece contour to save you
machining time.
For NC programs with normal vectors,
such as those generated by CAM systems,
the iTNC 530 automatically calculates a 3-D
tool compensation for end mills, ball-nose
cutters, or toroid cutters.
