Which operation mode runs part programs from the control's memory?

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

Answer: (C)

The correct choice, which indicates the operation mode that runs part programs from the control's memory, is "MEM." In this mode, the CNC machine reads the part program that has been stored in its internal memory. This allows for automated operation, where the machine can execute the sequence of instructions without continuous input from the operator during the machining process. In contrast, Manual Data Input (MDI) allows the operator to input commands one at a time directly into the control, which is useful for manual programming or test runs but does not utilize stored programs for full operations. DNC (Direct Numerical Control), often paired with MDI, refers to a method of controlling CNC machines via a computer network or direct connection but does not pertain to memory execution specifically. The OFFSET mode is used for adjusting tool positions or work offsets but does not relate to running stored part programs. Thus, the "MEM" mode is specifically designed for executing the stored part programs, making it the correct answer.
