The term 'feed rate' in CNC machining is defined as the speed at which the material is fed into the machine during the machining process. This is a critical parameter because it influences the efficiency, quality of the cut, and the lifespan of the cutting tool. A correctly set feed rate ensures optimal cutting conditions without overloading the tool or the machine, which can lead to excessive wear, damage, or poor finish quality.

In essence, while the speed of the cutting tool and the material being worked on are important factors in a CNC environment, the feed rate specifically pertains to how quickly the material is introduced in relation to the cutting operation. This distinction is crucial for setting proper machining parameters to achieve desired tolerances and surface finishes. The other options either refer to other machining concepts or do not accurately capture the meaning of 'feed rate'.
