15.1 Programming and Executing
Simple Machining Operations
The Positioning with Manual Data Input mode of operation is
particularly convenient for simple machining operations or to pre-
position the tool. It enables you to write a short program in
HEIDENHAIN conversational programming or in ISO format, and
execute it immediately. Fixed cycles, touch-probe cycles and special
functions (SPEC FCT key) of the TNC are also available in the MDI
mode of operation. The TNC saves the program automatically in the
$MDI file. In the Positioning with MDI mode of operation, the
additional status displays can also be activated.
