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.

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 a possibly dangerous situation

that may cause injuries if not avoided.

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.

HEIDENHAIN | TNC 620 | Conversational Programming User's Manual | 10/2015 7

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 817600-03

TNC 620 E 817601-03

TNC 620 Programming Station 817605-03

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 four axes

The machine manufacturer adapts the usable features of the TNC

to his machine by the 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.

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

Tool measurement with the TT

In order to find out about the actual features of your machine,

please contact the machine manufacturer.

Many machine manufacturers, including HEIDENHAIN, offer

programming courses for the TNCs. Participation in one of these

courses is recommended to familiarize yourself thoroughly with the

TNC functions.

Cycle Programming User's Manual:

All of the cycle functions (touch probe cycles

and machining cycles) are described in the Cycle

Programming User’s Manual. If you need this user's

manual, please contact HEIDENHAIN if required. ID:
