TNC Models, Software and
Features
This manual describes functions and features provided by
the TNCs with the following NC software number.
TNC Model NC Software No.
TNC 410 286 060-xx
TNC 410 286 080-xx
The machine tool builder adapts the useable features of the
TNC to his machine by setting machine parameters. Therefore, some of the functions described in this manual may
not be among the features provided by your machine tool.
TNC functions that may not be available on your machine
include:
■ Probing function for the 3-D touch probe
■ Digitizing option
■ Tool measurement with the TT 120
■ Rigid tapping
Please contact your machine tool builder to become familiar
with the individual implementation of the control on your
machine.
Many machine manufacturers, as well as HEIDENHAIN,
offer programming courses for the TNCs. We recommend
these courses as an effective way of improving your
programming skill and sharing information and ideas with
other TNC users.
Contents
Location of use
The TNC complies with the limits for a Class A device in
accordance with the specifications in EN 55022, and is
intended for use primarily in industrially-zoned areas.

1.1 The TNC 410
HEIDENHAIN TNC controls are shop-floor programmable
contouring controls for milling, drilling and boring machines, as well
as machining centers with up to four axes. You can program
conventional milling, drilling and boring operations right at the
machine with the easily understandable interactive conversational
guidance. You can also change the angular position of the spindle
under program control.
1.1 The TNC 410
Keyboard and screen layout are clearly arranged in a such way that
the functions are fast and easy to use.
Programming: HEIDENHAIN conversational and ISO formats
HEIDENHAIN conversational programming is an especially easy
method of writing programs. Interactive graphics illustrate the
individual machining steps for programming the contour. If a
production drawing is not dimensioned for NC, the HEIDENHAIN
FK free contour programming carries out the necessary calculations
automatically. Workpiece machining can be graphically simulated
during test run. It is also possible to program in ISO format or DNC
mode.
You can enter a program while the TNC is running another.
Compatibility
The TNC can execute all part programs that were written on
HEIDENHAIN controls TNC 150 B and later.

EDITING mode of operation, for example, you can have the TNC show
program blocks in the left window while the right window displays
programming graphics. You could also display help graphics for cycle
definition in the right window instead, or display only program blocks
in one large window. The available screen windows depend on the
selected operating mode.
To change the screen layout:

1.3 Modes of Operation
The TNC offers the following modes of operation for the various
functions and working steps that you need to machine a workpiece:
1.3 Modes of Operation
Manual Operation and Electronic
The Manual Operation mode is required for setting up the machine
tool. In this operating mode, you can position the machine axes
manually or by increments and set the datums.
The Electronic Handwheel mode of operation allows you to move the
machine axes manually with the HR electronic handwheel.
Soft keys for selecting the screen layout
The same selection is available as in the Positioning with MDI mode.
The TNC always shows the positions at left in the divided screen.
5HEIDENHAIN TNC 410
Positioning with Manual Data Input (MDI)
This mode of operation is used for programming simple traversing
movements, such as for face milling or pre-positioning.

1.5 Accessories: HEIDENHAIN 3-D
Touch Probes and Electronic
Handwheels
3-D Touch Probes
With the various HEIDENHAIN 3-D touch probe systems you can:
■ Automatically align workpieces
■ Quickly and precisely set datums
■ Measure the workpiece during program run
■ Digitize 3-D surfaces (option), and
■ Measure and inspect tools
TS 220 and TS 630 touch trigger probes
These touch probes are particularly effective for automatic
workpiece alignment, datum setting, workpiece measurement and
for digitizing. The TS 220 transmits the triggering signals to the TNC
via cable and is a cost-effective alternative for applications where
digitizing is not frequently required.
The TS 630 features infrared transmission of the triggering signal to
the TNC. This makes it highly convenient for use on machines with
automatic tool changers.
Principle of operation: HEIDENHAIN triggering touch probes feature
a wear resisting optical switch that generates an electrical signal as
soon as the stylus is deflected. This signal is transmitted to the
TNC, which stores the current position of the stylus as an actual
value.
During digitizing the TNC generates a program containing straight
line blocks in HEIDENHAIN format from a series of measured
position data. You can then output the program to a PC for further
processing with the SUSA evaluation software. This evaluation
software enables you to calculate male/female transformations or
correct the program to account for special tool shapes and radii that
differ from the shape of the stylus tip. If the tool has the same
radius as the stylus tip you can run these programs immediately.
TT 120 tool touch probe for tool measurement
The TT 120 is a triggering 3-D touch probe for tool measurement
and inspection. Your TNC provides three cycles for this touch probe
with which you can measure the tool length and radius
automatically— either with the spindle rotating or stopped.
The TT 120 features a particularly rugged design and a high degree
of protection, which make it insensitive to coolants and swarf. The
triggering signal is generated by a wear-resistant and highly reliable
optical switch.
1.5 Accessories: HEIDENHAIN 3-D Touch Probes and Electronic Handwheels
HR electronic handwheels
Electronic handwheels facilitate moving the axis slides precisely by
hand. A wide range of traverses per handwheel revolution is
available. Apart from the HR 130 and HR 150 integral handwheels,
HEIDENHAIN also offers the HR 410 portable handwheel.
