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.

Introduction

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.

90 Introduction
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 workpiecesQuickly and precisely set datumsMeasure the workpiece during program runMeasure 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

92 Introduction
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 482).

Position encoders and reference marks

The machine axes are equipped with position encoders that register the positions of the machine table or tool. Linear axes are usually equipped with linear encoders, rotary tables and tilting axes with angle encoders.
When a machine axis moves, the corresponding position encoder generates an electrical signal. The TNC evaluates this signal and calculates the precise actual position of the machine axis.

3.1 Fundamentals

If there is a power interruption, the calculated position will no longer correspond to the actual position of the machine slide. To recover this association, incremental position encoders are provided with reference marks. The scales of the position encoders contain one or more reference marks that transmit a signal to the TNC when they are crossed over. From that signal the TNC can re-establish the assignment of displayed positions to machine positions. For linear encoders with distance-coded reference marks, the machine axes need to move by no more than 20 mm, for angle encoders by no more than 20°.
With absolute encoders, an absolute position value is transmitted to the control immediately upon switch-on. In this way the assignment of the actual position to the machine slide position is re-established directly after switch-on.

Reference system

A reference system is required to define positions in a plane or in space. The position data are always referenced to a predetermined point and are described through coordinates.
The Cartesian coordinate system (a rectangular coordinate system) is based on the three coordinate axes X, Y and Z. The axes are mutually perpendicular and intersect at one point called the datum. A coordinate identifies the distance from the datum in one of these directions. A position in a plane is thus described through two coordinates, and a position in space through three coordinates.
Coordinates that are referenced to the datum are referred to as absolute coordinates. Relative coordinates are referenced to any other known position (reference point) you define within the coordinate system. Relative coordinate values are also referred to as incremental coordinate values.

When using a milling machine, you orient tool movements to the Cartesian coordinate system. The illustration at right shows how the Cartesian coordinate system describes the machine axes. The figure illustrates the right-hand rule for remembering the three axis directions: the middle finger points in the positive direction of the tool axis from the workpiece toward the tool (the Z axis), the thumb points in the positive X direction, and the index finger in the positive Y direction.
The iTNC 530 can control up to 18 axes. The axes U, V and W are secondary linear axes parallel to the main axes X, Y and Z, respectively. Rotary axes are designated as A, B and C. The illustration at lower right shows the assignment of secondary axes and rotary axes to the main axes.
In addition, the machine tool builder can define any number of auxiliary axes identified by lowercase letters

If the production drawing is dimensioned in Cartesian coordinates, you also write the NC program using Cartesian coordinates. For parts containing circular arcs or angles it is often simpler to give the dimensions in polar coordinates.
While the Cartesian coordinates X, Y and Z are three-dimensional and can describe points in space, polar coordinates are two-dimensional and describe points in a plane. Polar coordinates have their datum at a circle center (CC), or pole. A position in a plane can be clearly defined by the:
Polar Radius, the distance from the circle center CC to the position,
3.1 Fundamentals
and the
Polar Angle, the value of the angle between the angle reference axis
and the line that connects the circle center CC with the position.
Setting the pole and the angle reference axis
The pole is set by entering two Cartesian coordinates in one of the three planes. These coordinates also set the reference axis for the polar angle H.

Absolute workpiece positions
Absolute coordinates are position coordinates that are referenced to the datum of the coordinate system (origin). Each position on the workpiece is uniquely defined by its absolute coordinates.
Example 1: Holes dimensioned in absolute coordinates Hole 1 Hole 2 Hole 3
X = 10 mm X = 30 mm X = 50 mm Y = 10 mm Y = 20 mm Y = 30 mm
Incremental workpiece positions
Incremental coordinates are referenced to the last programmed nominal position of the tool, which serves as the relative (imaginary) datum. When you write an NC program in incremental coordinates, you thus program the tool to move by the distance between the previous and the subsequent nominal positions. This is why they are also referred to as chain dimensions.
To program a position in incremental coordinates, enter the function G91 before the axis.
Example 2: Holes dimensioned in incremental coordinates Absolute coordinates of hole 4 X = 10 mm
Y = 10 mm Hole 5, with respect to 4 Hole 6, with respect to 5
G91 X = 20 mm G91 X = 20 mm G91 Y = 10 mm G91 Y = 10 mm

Absolute and incremental polar coordinates
Absolute polar coordinates always refer to the pole and the angle reference axis.

A production drawing identifies a certain form element of the workpiece, usually a corner, as the absolute datum. When setting the datum, you first align the workpiece along the machine axes, and then move the tool in each axis to a defined position relative to the workpiece. Set the display of the TNC either to zero or to a known position value for each position. This establishes the reference system for the workpiece, which will be used for the TNC display and your part program.
If the production drawing is dimensioned in relative coordinates, simply use the coordinate transformation cycles (see User’s Manual
3.1 Fundamentals
for Cycle Programming, Cycles for Coordinate Transformation). If the production drawing is not dimensioned for NC, set the datum at
a position or corner on the workpiece from which the dimensions of the remaining workpiece positions can be most easily measured.
The fastest, easiest and most accurate way of setting the datum is by using a touch probe from HEIDENHAIN. See "Datum setting with touch probes" in the Touch Probe Cycles User’s Manual.
Example
The workpiece drawing shows holes (1 to 4) whose dimensions are shown with respect to an absolute datum with the coordinates X=0 Y=0. Holes 5 to 7 are dimensioned with respect to a relative datum with the absolute coordinates X=450, Y=750. With the DATUM SHIFT cycle you can temporarily set the datum to the position X=450, Y=750, to be able to program holes 5 to 7 without further calculations.
