What term refers to the rate at which the cutting tool and the workpiece move relative to each other?

The term that refers to the rate at which the cutting tool and the workpiece move relative to each other is known as the feed rate. The feed rate is a critical parameter in machining processes, as it influences both the surface finish of the machined part and the life of the cutting tool. It specifically defines how quickly the tool advances through the material, typically measured in units like inches per minute or millimeters per minute.

Understanding the feed rate is essential for optimizing machining operations, as it affects the amount of material removed during each pass and can impact the overall efficiency and quality of the machining operation. A properly set feed rate ensures that the cutting tool is not overloaded, which could lead to premature wear or failure while also achieving the desired accuracy and surface quality on the workpiece.
