What does "feed rate" refer to in milling?

Feed rate in milling specifically refers to the speed at which the workpiece is fed into the cutting tool. This measurement is crucial because it affects the cutting operation's efficiency, surface finish, and tool wear. A higher feed rate can lead to faster machining but may also result in diminished surface quality and increased tool wear, while a lower feed rate may enhance the surface finish but increase machining time.

Choosing the correct feed rate is essential for achieving optimal machining performance, making it a fundamental concept in milling operations. Understanding feed rate helps machinists balance production time with quality outcomes, ensuring efficient and effective use of milling equipment.
