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 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.

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 640 340590-01
TNC 640 E 340591-01
TNC 640 Programming Station 340594-01
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
TNC Model, Software and Features
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 640.
Please contact HEIDENHAIN if you require a copy of
this User’s Manual.

spindles as well as for linear motors and torque motors
HEIDENHAIN TNC 640 5
KinematicsOpt software option (option number #48)
Touch-probe cycles for inspecting and optimizing the machine
accuracy
Mill-Turning software option (option number #50)
Functions for milling/turning mode:
Switching between Milling/Turning mode of operation
Constant surface speed

Turning cycles
Extended Tool Management software option (option number
#93)
Tool management that can be changed by the machine
manufacturer using Python scripts
Feature content level (upgrade functions)
Along with software options, significant further improvements of the
TNC Model, Software and Features
TNC software are managed via the Feature Content Level (FCL)
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.
