  • Understanding tangential cutting force when milling

    May 01 2012 · The tangential cutting force if end users know how to determine it and the cutting speed which is selected as one of several machining parameters allow calculating the required machining power for an operation. When the required machining power value is about the same as the milling machine s rated power milling productivity approaches The function of oil film is to reduce fr iction force but it always produces tangential force to hinder movement 2 3 . Even if the friction force is reduced to the minimum the existing friction consumption could still decrease machinery efficiency 4 5 . Shear stress of oil film is correlated with film flow velocity.
