Final answer:
Cutting fluids have several chief functions in the machining process including lubrication, cooling, and chip removal.
Step-by-step explanation:
Cutting fluids have several chief functions in the machining process:
Lubrication: Cutting fluids reduce friction between the cutting tool and the workpiece, preventing wear and heat buildup. This allows for smoother cutting and increases tool life.
Cooling: Cutting fluids dissipate heat generated during the machining process, preventing thermal damage to the tool and workpiece. They also keep the temperature of the cutting zone consistent, which is important for dimensional accuracy.
Chip removal: Cutting fluids help flush away chips and debris from the cutting zone, improving the visibility for the operator and preventing re-cutting of chips.
These functions enhance the efficiency, quality, and safety of the machining process.
