Which key would you use to decrease the current spindle speed by 10%?

• A. 100% SPINDLE
• B. +10 SPINDLE
• C. -10 SPINDLE
• D. 50% RAPID

Answer: (C)

To decrease the current spindle speed by 10%, the function associated with the key specifically designed for this adjustment is the one labeled for a negative change in spindle speed. The correct choice effectively reduces the speed, indicating a decrement of 10% from the current setting. In this scenario, the key that performs this function directly corresponds to a negative adjustment, allowing the operator to finely control the spindle speed for the desired machining conditions. Understanding this function is crucial for CNC operators, as spindle speed adjustments often need to be made to accommodate various material specifications, tooling, and desired machining outcomes. The other options relate to spindle speed adjustments but are either meant for increasing speed or are not specifically designed for reducing spindle speed by a set percentage. Knowing how to control spindle speed accurately is essential for maintaining optimal machining performance and ensuring the quality of the finished product.
