Modeling of Cutting Forces in End Milling Operations

In the simulation model the most significant influence on the forces is the chip thickness (Tc) However the dynamic radius caused by cutter runout and tilt is another key point to affect chip thickness The effect of feed per flute on milling forces is apparent from Figure 4 (a) (b) (c) and (d)
