How can cutting fluid affect tool life?

• A. By shortening the tool's lifespan
• B. By prolonging tool life through reducing wear
• C. By increasing tool weight
• D. By introducing contaminants

Answer: (B)

Cutting fluid plays a crucial role in enhancing tool life by reducing wear on the tool during machining processes. The fluid lubricates the cutting tool and workpiece interface, which minimizes friction and heat generated during cutting. This reduction in heat helps maintain the tool's hardness and cutting edge integrity, ultimately prolonging its effective lifespan. Additionally, cutting fluids can help to remove chips from the cutting zone, which further protects the cutting edges from damaging interactions with the workpiece. By facilitating cooling and reducing thermal shock, cutting fluids contribute significantly to improved tool performance and extended longevity. These factors are vital in a CNC milling environment where maintaining tool efficiency can impact productivity, cost, and part quality.
