The role of flank face interference in improving the accuracy of dynamic force predictions in peripheral milling

An enhanced model for the dynamic behavior of the peripheral milling proces s is described The model predicts the cutting forces and cutter deflections by including the effects of the flank face interference mechanism in addit ion to the chip removal effects. The interference mechanism is accounted fo r by considering the flank interference forces to be proportional to the in terference volume. The volume of interference is estimated numerically. The total force acting on the tool is a combination of the forces dire to the cutting action and forces due to the interference. Experiments performed on 6061-T6 Aluminum validate the simulation results.
