What key allows an operator to enter and execute program data without disturbing stored data when pressed once?

• A. MDI/DNC
• B. MEM
• C. TOOL OFFSET
• D. Manual Input

Answer: (A)

The MDI (Manual Data Input) key is specifically designed to allow operators to input program data into the CNC machine without altering any of the stored programs in the machine's memory. When the operator presses the MDI key, it enables a temporary mode that allows for the execution of commands or programs that the operator inputs at that moment; however, once that command is executed, it does not affect any previously saved programs or settings. This is particularly useful for making quick adjustments, testing out new programs, or troubleshooting without the risk of modifying other essential data stored in the machine. The other options provided serve different purposes. The MEM key typically relates to memory functions but does not directly facilitate the temporary input and execution of commands like MDI. TOOL OFFSET refers to adjustments in tool measurements and would not be related to program data input. Manual Input may imply entering data directly, but it doesn’t specifically reference the temporary execution feature that MDI provides.
