Drilling formulas The material removal rate ( MRR ) in drilling is the volume of material removed by the drill per unit time. For a drill with a diameter D, the cross-sectional area of the drilled hole is πD2 /4 . The velocity of the drill perpendicular to the workpiece f is the product of the feed fr and the rotational speed N where N = V / π D .

Jan 15, 2001 · For the maximum depth achieved prior to chatter, compute the metal removal rate. MRR equals feed rate × axial depth of cut × radial depth of cut. It may also be useful to note the spindle load. MRR and spindle load will help you compare the best the machine was able to do at this speed with the best it can do at other speeds.

Machining is a term used to describe a variety of material removal processes in which a cutting tool removes unwanted material from a workpiece to produce the desired shape. The workpiece is typically cut from a larger piece of stock, which is available in a variety of standard shapes, such as flat sheets, solid bars, hollow tubes, and shaped beams.
