1.2 Machine switch-on
Acknowledging the power interruption and moving to the reference points
Switch-on and crossing the reference points can vary
depending on the machine tool. Your machine manual
provides more detailed information.
Switch on the power supply for control and machine. The TNC starts
the operating system. This process may take several minutes. Then
the TNC will display the message "Power interrupted" in the screen
header
Press the CE key: The TNC compiles the PLC program
Switch on the control voltage: The TNC checks
operation of the emergency stop circuit and goes into
the reference run mode
Cross the reference points manually in the displayed
sequence: For each axis press the machine START
button. If you have absolute linear and angle encoders
on your machine there is no need for a reference run
The TNC is now ready for operation in the Manual Operation mode.

Creating a new program/file management
Press the PGM MGT key: The TNC opens the file
manager. The file management of the TNC is
arranged much like the file management on a PC with
the Windows Explorer. The file management enables
you to manipulate data on the TNC hard disk
Use the arrow keys to select the folder in which you
want to open the new file
Enter a file name with the extension .H: The TNC then
automatically opens a program and asks for the unit
of measure for the new program. Please note the
restrictions regarding special characters in the file
name (see "File names" on page 122)
To select the unit of measure, press the MM or INCH
soft key: The TNC automatically starts the workpiece
blank definition (see "Defining a workpiece blank" on
page 60)
The TNC automatically generates the first and last blocks of the
program. Afterwards you can no longer change these blocks.

Program layout
NC programs should be arranged consistently in a similar manner. This
makes it easier to find your place, accelerates programming and
reduces errors.
Recommended program layout for simple, conventional contour
machining
1 Call the tool, define the tool axis
2 Retract the tool
3 Preposition the tool in the working plane near the contour starting
point
4 In the tool axis, position the tool above the workpiece, or
preposition immediately to workpiece depth. If required, switch on
the spindle/coolant
5 Approach the contour
6 Machine the contour
7 Depart the contour
8 Retract the tool, end the program
Further information on this topic:
Contour programming: See "Tool movements", page 222
Recommended program layout for simple cycle programs
1 Call the tool, define the tool axis
2 Retract the tool
3 Define the machining positions
4 Define the fixed cycle
5 Call the cycle, switch on the spindle/coolant
6 Retract the tool, end the program

2.1 The iTNC 530
HEIDENHAIN TNC controls are workshop-oriented contouring
controls that enable you to program conventional machining
operations right at the machine in an easy-to-use conversational
programming language. They are designed for milling, drilling and
boring machines, as well as for machining centers. The iTNC 530 can
control up to 18 axes. You can also change the angular position of up
to 2 spindles under program control.
An integrated hard disk provides storage for as many programs as you
like, even if they were created off-line. For quick calculations you can
2.1 The iTNC 530
call up the on-screen pocket calculator at any time.
Keyboard and screen layout are clearly arranged in such a way that the
functions are fast and easy to use.
Programming: HEIDENHAIN conversational, smarT.NC and ISO formats
The HEIDENHAIN conversational programming format 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 FK free contour
programming feature performs the necessary calculations
automatically. Workpiece machining can be graphically simulated
either during or before actual machining.
The smarT.NC operating mode offers TNC beginners an especially
simple possibility to quickly and without much training create
structured conversational dialog programs. Separate user
documentation is available for smarT.NC.
It is also possible to program the TNCs in ISO format or DNC mode.
You can also enter and test one program while the control is running
another.
Compatibility
The TNC can run all part programs that were written on HEIDENHAIN
contouring controls starting from the TNC 150 B. In as much as old
TNC programs contain OEM cycles, the iTNC 530 must be adapted to
them with the PC software CycleDesign. For more information,
contact your machine tool builder or HEIDENHAIN.

96 Introduction
Page 97
2.6 SELinux security software
SELinux is an extension for Linux-based operating systems. SELinux
is an additional security software package based on Mandatory
Access Control (MAC) and protects the system against the running of
unauthorized processes or functions and therefore protects against
viruses and other malware.
MAC means that each action must be specifically permitted otherwise
the TNC will not run it. The software is intended as protection in
addition to the normal access restriction in Linux. Certain processes
and actions can only be executed if the standard functions and access
control of SELinux permit it.
The SELinux installation of the TNC is prepared to permit
running of only those programs installed with the
HEIDENHAIN NC software. You cannot run other
programs with the standard installation.
The access control of SELinux under HEROS 5 is regulated as follows:
The TNC runs only those applications installed with the
HEIDENHAIN NC software.
Files in connection with the security of the software (SELinux
system files, HEROS 5 boot files, etc.) may only be changed by
programs that are selected explicitly.
New files generated by other programs must never be executed.
There are only two processes that are permitted to execute new
files:
Starting of a software update
A software update from HEIDENHAIN can replace or change
system files.
Starting of the SELinux configuration
The configuration of SELinux is usually password-protected by
your machine tool builder. Refer here to the relevant machine tool
manual.
2.6 SELinux security software
HEIDENHAIN generally recommends activating SELinux
because it provides additional protection against attacks
from outside.

2.7 Accessories: HEIDENHAIN
touch probes and electronic
handwheels
Touch probes
The various HEIDENHAIN touch probes enable you to:
Automatically align workpieces
Quickly and precisely set datums
Measure the workpiece during program run
Measure and inspect tools
All of the touch probe functions are described in the
User’s Manual for Cycles. Please contact HEIDENHAIN if
you require a copy of this User’s Manual. ID: 670388-xx.
Please note that HEIDENHAIN grants a warranty for the
function of the touch probe cycles only if HEIDENHAIN
touch probes are used!
TS 220, TS 640 and TS 440 touch trigger probes
These touch probes are particularly effective for automatic workpiece
alignment, datum setting and workpiece measurement. The TS 220
transmits the triggering signals to the TNC via cable and is a costeffective alternative for applications where digitizing is not frequently
required.
The TS 640 (see figure) and the smaller TS 440 feature infrared
transmission of the triggering signal to the TNC. This makes them
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
control, which stores the current position of the stylus as the actual
value.
2.7 Accessories: HEIDENHAIN touch probes and electronic handwheels
98 Introduction
Page 99
TT 140 tool touch probe for tool measurement
The TT 140 is a triggering 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 140 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.
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 HR130 and HR150 integral handwheels, HEIDENHAIN
also offers the HR 520 and HR 550 FS portable handwheels. You will
find a detailed description of HR 520 in Chapter 14 of this manual (see
"Traversing with electronic handwheels" on page 570).
