What CNC technology monitors machine functions in real time?

• A. Sensors
• B. Actuators
• C. Encoders
• D. PLCs

Answer: (A)

Real-time monitoring is done by sensors because they continuously measure physical conditions and feed that data back to the CNC control. This allows the system to watch for things like temperature, vibration, spindle load, and tool wear, and to adjust parameters or stop the machine if something looks off. Actuators are the parts that create motion or force; they don’t monitor conditions themselves. Encoders provide position and speed feedback, which is essential for control, but they’re a specific type of sensor focused on motion measurement rather than monitoring a broad range of machine functions. PLCs manage and process signals to control operations, but they aren’t the sensing elements that continuously observe machine conditions.
