What is the primary function of cutting fluids?

The primary function of cutting fluids encompasses multiple aspects critical to machining operations, which is why the comprehensive choice of "all of the above" is correct.

Cutting fluids serve to cool both the workpiece and the cutting tool during machining processes. The heat generated from the cutting action can significantly affect the tool and the material being worked on, potentially leading to thermal expansion, tool wear, and a compromised workpiece structure. By cooling the surfaces, cutting fluids help to maintain an optimal operating temperature, which enhances the quality of the cut and extends tool life.

Additionally, cutting fluids also act as lubricants. They reduce friction between the cutting tool and the workpiece, resulting in smoother operations and further conserving the integrity of both the tool and the material. This lubrication aspect helps in minimizing wear, preventing galling, and reducing the overall force required during machining, which can improve efficiency.

Moreover, cutting fluids can improve the durability of tools by preventing chip buildup, controlling oxidation, and mitigating wear patterns that can result from heat and friction. They can also assist in flushing away chips and debris from the cutting area, which helps to maintain a clear cutting path and improves the overall effectiveness of the machining operation.

By fulfilling these roles collectively, cutting fluids optimize machining processes
