Why is it important to maintain proper cutting speeds?

Maintaining proper cutting speeds is crucial primarily because it significantly extends tool life and improves the surface finish of the workpiece. When cutting tools operate at optimal speeds, they cut through materials with less friction and heat generation, reducing wear on the tool. This allows the cutting edge to remain sharp for a longer duration, which not only extends the life of the tool but also enhances the overall quality of the machining process.

Furthermore, the right cutting speed is essential for achieving a smooth surface finish. If the speed is too low, it can result in rough finishes due to inadequate removal of material. Conversely, if the speed is too high, it may lead to excessive heat and tool wear, compromising both the tool's integrity and the surface quality. Therefore, selecting the appropriate cutting speed is critical for both efficiency and quality in machining operations.
