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:

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
