TNC 426/TNC 425/TNC 415 B/TNC 407 1-3
1 Introduction
Visual display unit and keyboard
The 14-inch color monitor displays all the information necessary for
effective use of the TNC's capabilities.
The keys are grouped on the keyboard according to function. This makes it
easier to create programs and to use the TNC’s functions.
Programming
The TNCs are programmed in ISO format.
It is also possible to program in easy-to-understand HEIDENHAIN
conversational format (a separate User's Manual is available for this).
Graphics
Workpiece machining can be graphically simulated both during machining
(except on TNC 407) or before actual machining. Various display modes are
available.
Compatibility
The TNCs can execute all part programs written on HEIDENHAIN
TNC 150 B controls or later.
