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 530 340 422-xx

iTNC 530E 340 423-xx

iTNC 530, dual-processor version 340 480-xx

iTNC 530E, dual-processor version 340 481-xx

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

n 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.

Some TNC functions have to be implemented by the machine tool builder and are therefore not universally available on all machines. These functions include:

n Probing function for the 3-D touch probe n Tool measurement with the TT 130 n Rigid tapping n Returning to the contour after an interruption

HEIDENHAIN iTNC 530 5

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:

n M114: Automatic compensation of machine geometry when

working with tilted axes

n M128: Maintaining the position of the tool tip when positioning

with tilted axes (TCPM)

n M144: Compensating the machine’s kinematic configuration for

ACTUAL/NOMINAL positions at end of block

n Additional parameters finishing/roughing and tolerance for

rotary axes in Cycle 32 (G62)

n 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: 375 319-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.

HEIDENHAIN iTNC 530 7

Functions changed since the predecessor versions 340420-xx and 340 421-xx

datums are no longer available. Instead, the preset table was introduced (see “DATUM SHIFT with datum tables (Cycle G53)” on page 381)

n The function of Cycle 247 was changed. Cycle 247 now activates a

preset from the preset table (see “DATUM SETTING (Cycle G247)” on page 384)

n Machine parameter 7475 is now meaningless (see “Compatibility

machine parameters for datum tables” on page 518)
