3.1 Positioning with Manual Data
Input (MDI)
The POSITIONING WITH MANUAL DATA INPUT mode of operation is
particularly convenient for simple machining operations or exact pre-
positioning of the electrode. You can write a program in conversational
programming and execute it immediately. You can also define and call
TNC cycles. The program is stored in the file $MDI.
Positioning with manual data input (MDI)
