About this Manual

The symbols used in this manual are described below.

This symbol indicates that important information

about the function described must be considered.

WARNING This symbol indicates a possibly

dangerous situation that may cause light injuries if

not avoided.

This symbol indicates that there is one or more

of the following risks when using the described

function:

Danger to workpiece

Danger to fixtures

Danger to tool

Danger to machine

Danger to operator

This symbol indicates that the described function

must be adapted by the machine tool builder. The

function described may therefore vary depending on

the machine.

This symbol indicates that you can find detailed

information about a function in another manual.

Would you like any changes, or have you found any

errors?

We are continuously striving to improve our documentation for you.

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

TNC 620 817600-01

TNC 620 E 817601-01

TNC 620 Programming Station 817605-01

The suffix E indicates the export version of the TNC. The export

version of the TNC has the following limitations:

Simultaneous linear movement in up to 4 axes

The machine tool builder adapts the usable features of the TNC to

his machine by setting machine parameters. Some of the functions

described in this manual may therefore not be among the features

provided by the TNC on your machine tool.

TNC functions that may not be available on your machine include:

Tool measurement with the TT

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.

User's Manual:

All TNC functions that have no connection with

cycles are described in the User's Manual of the TNC

620. Please contact HEIDENHAIN if you require a

copy of this User’s Manual.

Feature Content Level (upgrade functions)

Along with software options, significant further improvements

of the TNC software are managed via the Feature Content Level

upgrade functions. Functions subject to the FCL are not available

simply by updating the software on your TNC.

All upgrade functions are available to you without

surcharge when you receive a new machine.

Upgrade functions are identified in the manual with FCL n, where n

indicates the sequential number of the feature content level.

You can purchase a code number in order to permanently enable

the FCL functions. For more information, contact your machine tool

builder or HEIDENHAIN.

Intended place of operation

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.

New cycle functions of software 73498x-02

10 TNC 620 | User's Manual Cycle Programming | 3/2014

New cycle functions of software 73498x-02

New fixed cycle 225 Engraving, see "ENGRAVING (Cycle 225,

DIN/ISO: G225)", page 284

With Cycle 256, Rectangular Stud, a parameter is now available

with which you can determine the approach position on the

stud, see "RECTANGULAR STUD (Cycle 256, DIN/ISO: G256,

software option 19)", page 150

With Cycle 257, circular stud milling, a parameter is now

available with which you can determine the approach position

on the stud, see "CIRCULAR STUD (Cycle 257, DIN/ISO: G257,

software option 19)", page 154

Cycle 402 now also allows you to compensate workpiece

misalignment by rotating the rotary table, see "BASIC

ROTATION over two studs (Cycle 402, DIN/ISO: G402, software

option 17)", page 306

New Touch Probe Cycle 484 for calibrating the wireless TT 449

touch probe, see "Calibrate the wireless TT 449 (Cycle 484, DIN/

ISO: G484, software option 17 Touch Probe Functions software

option 17)", page 473

New manual probing cycle "Center line as datum" (see User's

Manual)

Predefined values can now be entered into a cycle parameter

with the PREDEF function in cycles, see "Program defaults for

cycles", page 50

The following improvements were made to the KinematicsOpt

cycles:

Newer, faster optimization algorithm

After angle optimization, a separate measurement series

is no longer required for position optimization, see "Various

modes (Q406)", page 452

Return of the offset errors (change of machine datum) to the

parameters Q147 to 149, see "Cycle run", page 440

Up to eight plane measuring points for the measurement of

spheres, see "Cycle parameters", page 449

The active tool-axis direction can now be activated in manual

mode and during handwheel superimposition as a virtual tool

axis (see User's Manua).
