EML 2322L -- MAE Design and Manufacturing Laboratory Milling Speeds and Feeds Like a drill bit, the speed of a milling cutter is usually measured in terms of the rate at which the outside, or periphery, of the tool moves in relation to the work being milled. General sfm guidelines are commonly found in resources such as the Machinery Handbook (refer again to Table 1 in this document). The peripheral and rotational velocities of the tool are related by the same equation: V = π * D * N (Eq. 1) where V is the recommended peripheral velocity for the tool being used D is the diameter of the tool N is the rotational velocity of the tool Since the peripheral velocity is commonly expressed in units of feet/min and tool diameter is typically measured in units of inches, Equation 1 can be solved for the spindle or tool velocity, N in the following manner: N [rpm] = 12 [in/ft] * V [sfm] / ( π * D [in]) (Eq. 2) Equation 2 will provide a guideline as to the maximum rpm when milling standard materials. The optimum speed for a particular setup is affected by many factors, including the following: Composition, hardness & thermal conductivity (k) of material
