Which method of applying cutting fluid involves letting the fluid drip onto the work area instead of flooding or spraying?

• A. Drip method
• B. Flood method
• C. Mist method
• D. Spray method

Answer: (A)

Drip delivery uses gravity to let cutting fluid fall slowly onto the cutting zone, delivering lubrication and cooling right at the point of contact with minimal fluid use. This approach keeps the fluid near the work area without flooding it or spraying a wide area, which helps avoid splatter and excessive washout of chips. It’s ideal when you want localized lubrication with control over how much fluid reaches the interface. In contrast, flooding wets a large area with a high volume of fluid, spraying or misting spreads fluid more broadly or as a fine aerosol, which can use more fluid and affect surface finishes or chip control. Therefore, letting the fluid drip onto the work area is the correct method.
