3.1 Programming and Executing
Simple Machining Operations
The Positioning with Manual Data Input mode of operation is
particularly convenient for simple machining operations or pre-
positioning of the tool. It enables you to write a short program in
HEIDENHAIN conversational programming or in DIN/ISO format, and
execute it immediately. You can also call TNC cycles. The program is
stored in the file $MDI. In the Positioning with MDI operating mode,
the additional status displays can also be activated.
Positioning with Manual Data Input (MDI)
