A top view of the tool, i.e., looking down on the tool rake face, is provided in the animation. The shaded area on the tool face represents the ( depth of cut ) by ( feed distance ) cross section area of the workpiece being removed. The material removal rate is this cross section area times the cutting speed. The cutting speed is the rate at which the work moves past the cutting edge and so is equivalent to the speed with which this cross section moves through the workpiece.
