What key restores the feed rate to the full programmed value?

• A. 100% SPINDLE
• B. 5% RAPID
• C. 100% FEEDRATE
• D. -10 SPINDLE

Answer: (C)

The key that restores the feed rate to the full programmed value is the one that specifically indicates a return to the full feed rate settings. In CNC operations, the feed rate defines how quickly the tool advances during cutting, which is crucial for ensuring proper machining performance and surface finish. The correct choice indicates a full restoration of the programmed feed rate, meaning the machine will operate at the intended speed as defined by the CNC program. This is significant in various machining tasks since the feed rate affects material removal, tool life, and overall efficiency. Other options represent different functionalities which do not pertain directly to restoring the feed rate to its full programmed value. For example, the spindle control keys typically affect the rotational speed of the spindle rather than the feed rate. Similarly, rapid settings would typically be faster than programmed feeds, indicating non-cutting movement rather than the outlined cutting operation. Understanding these distinctions is essential for effectively managing machine settings during operation.
