Copy Mills • M370™ Series Additional Application Advice • WO.J0804... Applying High-Feed Tools The high-feed concept bases its strategy on small depth of cut and higher fz values, which results in a higher MRR and productivity with low radial forces. Ap1 max Rt Wt Wt t Small Ap1 values and higher feed For CAM programming, the tools Recommended when long rates generate lower cutting forces can be programmed as a toroidal overhang is necessary due to versus traditional milling strategies. tool type by using the Rt value as lower radial forces.
