Programming, editing, testing
– The TNC 640 opens endless possibilities
The TNC 640 is just as universal in
application as it is fl exible in machining and
programming.
Positioning with Manual Data Input
You can start working with the TNC 640
even before writing a complete part
program. Simply machine a part step by
step—switching as you want between
manual operation and automatic
positioning.
Programming at the machine
HEIDENHAIN controls are workshop
oriented, which means that they were
conceived for programming right at the
machine. With conversational programming
you can forget about memorizing G codes.
Instead you use dedicated keys and soft
keys to program line segments, circular
arcs and cycles. With a keystroke, you
initiate a HEIDENHAIN plain-language
dialog, and the TNC begins immediately to
support you actively in your work. Unam-
biguous questions and prompts help you
enter all the required information.
Whether plain-language prompts, dialog
guidance, programming steps or soft
keys, all texts are available in numerous
languages.
And if you are used to G-code program-
ming, then the TNC is still the right control
for you: you can use the G-code keyboard
to enter the calculations, or enter them
directly with the QWERTY keyboard.
Creating programs offl ine
The TNC 640 is also well equipped for
offl ine programming. Through its interfaces
it can be integrated into networks and
connected with programming stations or
other data storage devices.
