TNC Model, Software and Features

This manual describes functions and features provided by TNCs as of the following NC software numbers.

TNC model	NC software number
iTNC 530	340 420-xx
iTNC 530E	340 421-xx

The suffix E indicates the export version of the TNC. The export version of the TNC has the following limitations:

Linear movement is possible in no more than 4 axes simultaneously.

The machine tool builder adapts the useable features of the TNC to his machine by setting machine parameters. 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

Tool measurement with the TT 130

Rigid tapping

Returning to the contour after an interruption

HEIDENHAIN iTNC 530

I

In addition, the iTNC 530 also has two software option packets that can be enabled by you or your machine tool builder:

Software option 1

Cylinder surface interpolation (Cycles 27 and 28)

Feed rate in mm/min on rotary axes: M116

Tilting the machining plane (Cycle 19 and 3D-ROT soft key in the manual operating mode)

Circle in 3 axes (with tilted working plane)

Software option 2

Block processing time 0.5 ms instead of 3.6 ms

5 axis interpolation

Spline interpolation

3-D machining:

M114: Automatic compensation of machine geometry when working with tilted axes

M128: Maintaining the position of the tool tip when positioning with tilted axes (TCPM)

M144: Compensating the machine’s kinematic configuration for ACTUAL/NOMINAL positions at end of block

Additional parameters finishing/roughing and tolerance for rotary axes in Cycle 32 (G62)

LN blocks (3-D compensation)

Please contact your machine tool builder to become familiar with the features of 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.

Touch Probe Cycles User’s Manual:

All of the touch probe functions are described in a separate manual. Please contact HEIDENHAIN if you require a copy of this User’s Manual. ID number: 369 280-xx.

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.

II

New features of the NC software 340 420-xx

Connecting the TNC to Windows networks via Ethernet (see “Network settings specific to the device” on page 454)

Definition of overlapping contours with contour formula (see “SL Cycles with Contour Formula” on page 321)

Stepwise magnification/reduction in the test graphic (see “Rotating and magnifying/reducing the 3-D view” on page 425)

The additional status display was expanded to display the active datum table and the active datum number (see “Coordinate transformations” on page 11).

Find/Replace any text (see “The TNC search function” on page 70)

Changing the position of the current block on the screen (see “Editing a program” on page 67)

New Q parameter functions: Check sign and Calculate modulo value when entering formulas (see “Entering Formulas Directly” on page 404)

Generating a file with version numbers (see “Code Numbers” on page 445)

Plunging feed rate for infeed for finishing new in Cycles 210 and 211 (see “SLOT (oblong hole) with reciprocating plunge-cut (Cycle 210),” page 281 and see “CIRCULAR SLOT (oblong hole) with reciprocating plunge-cut (Cycle 211),” page 283)

HEIDENHAIN iTNC 530

III

Changed features of the NC software 340 420-xx

Cycle 32 Tolerance was expanded so that different filter settings can be selected for High Speed Cutting (HSC) (see “TOLERANCE (Cycle 32)” on page 359).

In Cycle 210 (Slot with reciprocating plunge), the approach behavior for finishing was changed (see “SLOT (oblong hole) with reciprocating plunge-cut (Cycle 210)” on page 281).

The additional status display was expanded to display the active status of program section repeats and subprogram calls.(see “Program section repeats/subprograms” on page 12)

When contents of Q parameters are checked, 16 parameters are now shown in a separate window.(see “Checking and Changing Q Parameters” on page 386)

The number of contour elements permitted in SL Cycles, Group II, has been increased from approx. 256 to approx. 1024 (see “SL Cycles” on page 294).

The transfer of the current tool position coordinates into the program has been improved (see “Actual position capture” on page 66).

The transfer of the value that is calculated by using the on-screen pocket calculator into the program has been modified (see “Integrated Pocket Calculator” on page 80).

Detail magnification is now also possible in plan view (see “Magnifying details” on page 426).

When program sections are copied, the copied block remains highlighted after having been inserted (see “Marking, copying, deleting and inserting program sections” on page 69).

Introduction

1.1 The iTNC 530

1.1 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 12 axes. You can also change the angular position of the spindle 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 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 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 does the necessary calculations automatically. Workpiece machining can be graphically simulated either during or before actual machining. It is also possible to program 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 controls TNC 150 B and later.
