aph INDEXABLE MILLING CALCULATING ACTUAL CUTTING SPEED 1. Effective cutting diameter = 2 ap (DC-ap) DC DC: Tool diameter (inch) ap : Depth of Cut (inch) 2. Using ap Calculate cutting speed at the depth of cut line. vc = ap(DC-ap) vc : Actual cutting speed (SFM) n : Revolution (min-1) Effectivecutting diameter SELECTING PICK FEED Theoretical h : Cusp height h= Pf : Pick feed PRFRAD : Ball nose or corner radius Actual surface roughness Rz will be about 3 times worse than theoretical h. This is because of the effect of a built-up edge. To determine Pf, use the formula below based on a particular Rz value. Pf = 8xPRFRADxRz Pf L L273
