 General New Features
A number of new programming features
support the machinist and open new
possibilities.
Contour pockets: Subcontours can have
different depths (upgrade function)
The powerful contour pocket function is
available for machining complex contours.
In smarT.NC you can define up to 9 sub-
contours (pockets or islands), and in
conversational programming up to 12 sub-
contours, for machining a contour pocket.
These subcontours can contain up to 8192
contour elements. Until now the depth of a
pocket was globally specified. Now you
can assign a separate depth to each
subcontour. If the subcontour is an island,
the iTNC interprets the  depth entered as
the height of the island.
Separate depths are definable for subcontours
Separate machining units are now
available in smarT.NC for fine roughing,
side finishing and floor finishing, thereby
complementing the machining of a
contour pocket.
Cutting speed vc as alternate entry to
the spindle shaft speed S
When selecting a tool, you can now enter
a cutting speed vc in m/min instead of the
spindle speed S in rpm.
Freely definable tables in form view
The iTNC can now show all freely definable
tables, meaning all tables of file type .TAB,
in a form view. This view is especially
useful for large amounts of data.
Expanded look-ahead
In order to machine contours rapidly, the
control calculates the geometry ahead of
time previously up to 256 blocks. Usually
this suffices completely. Today s comput-
ing power, however, makes it possible to
calculate further in advance. The machine
manufacturer can now parameterize the
look-ahead function through a machine
parameter. The maximum value is 1024
blocks for a look-ahead capability
covering four times as many blocks as
before. This will only have an effect in NC
Tables in form view are freely definable
programs with extremely short positioning
blocks.

New Programming Functions
 smarT.NC
Mid-program startup with graphic
support (upgrade function)
The pattern generator in smarT.NC is a
powerful feature for defining machining
positions flexibly and with graphic support.
The positions are saved blockwise in point
tables for convenient reuse at other
locations for other operations. Now the re-
entry into a machining program has been
adapted to this flexible function: smarT.NC
detects your entry into a unit in which
machining positions are defined, and
symbolically displays the positions in a
preview window. You can now select via
soft key at which position you would like to
begin machining. smarT.NC then auto-
matically inserts the appropriate tool and
traverses to the selected position of
course only after your approval.
smarT.NC: mid-program startup
CUT/COPY/PASTE of one or more units
Using the key combinations you are
familiar with from Windows, you can copy
an entire unit or insert it at any other
location in the program. Naturally, the
SELECT BLOCK function you know from
conversational programming is also
available for the copying and pasting of
multiple units.
Feed rate also possible as FZ/FU/FMAX
When specifying the feed rate, you can
also enter a revolution feed rate in mm/rev
or a cutting feed rate mm/tooth instead of
in mm/min.

Tooltips displayed when using the
mouse
If you hold the mouse over an entry field or
selection box for more than one second,
the iTNC displays a tooltip. Tooltips contain
information or important notes about the
respective function.
Tool data editable during tool selection
In the pop-up window for tool selection
you can now also change the tool data
shown there. The TNC automatically saves
these changes in the tool table TOOL.T.
Axis keys now position the cursor in
forms as well
Up to now, experienced conversational
dialog programmers have been wanting to
use the orange axis keys in smarT.NC for
smarT.NC: Tooltips when using the mouse
contour programming. Now they can. The
orange I key (incremental/absolute
switchover) and P key (polar/rectangular
switchover) can now also be used.
Automatic entry of workpiece blank
into contour program
When you create a new contour program,
smarT.NC automatically takes the work-
piece blank defined in the unit program.
This transfer can be updated by soft key at
any time.
Incremental entry of machining
positions
When defining the positions directly in the
form for each machining unit, the positions
can now also be entered incrementally.

 Conversational Programming
Point filter for smoothing NC programs

With this TNC function you can make
contours smoother that were created on
external programming systems. The filter
function creates a copy of the original
program, and then adds any points
required by the parameters that you set.
This smoothes the contour to allow the
program to run more quickly and with
less jerk.

 Programming Station
Since the beginning of this year, the iTNC
programming station has been shipped with
a new keyboard. The new keyboard has a
much leaner housing and includes the new
smarT.NC keys. The following improvements
are available in the programming station
version 340 494-02.
" All software options and FCL
functions fully enabled
One special benefit: the complete array
of software options and FCL functions
available for the control are fully enabled
here. This enables users of the licensed
or free demo versions (download at
www.heidenhain.de/service) to amply
test all functions and then decide
whether an upgrade on the machine is
worthwhile.
" Virtual keyboard
Especially the users of the demo version
of the programming station can get an
even better idea of how easy it is to
operate the TNC using the keyboard.
Use the iTNC control panel to open a
virtual TNC keyboard on the screen,
providing the control s most important
dialog initiation keys. You will need a
screen resolution of at least 1280x1024
to be able to see the control screen and
the virtual keyboard at the same time.
" PLC basic program optionally
installable
When installing the programming station
software, you can now also install the
PLC basic program. This lets you
perform a  dry run in the Program Run
modes with the programs created on the
programming station, and the position
display runs as well.
