What does "feed rate" refer to in FANUC systems?

Feed rate in FANUC systems refers to the speed at which the cutting tool moves through the material being machined. This movement is critical because it directly influences the efficiency of the machining process, the quality of the finished product, and the tool life. By optimizing the feed rate, operators can control the depth of cut, the resultant surface finish, and the overall productivity of the machining operation.

In CNC operations, the feed rate is expressed in units such as inches per minute (IPM) or millimeters per minute (MPM), depending on the measurement system being used. A well-calibrated feed rate ensures that the tool effectively removes material without causing excess wear or damage.

The other choices represent concepts related to machining but do not accurately define the term "feed rate." The rate of coolant application pertains to the cooling and lubrication during machining, the power output of the machine relates to its performance capabilities, and the spindle rotation speed deals with how quickly the tool spins, all of which are important but distinct from the feed rate itself.
