In this work, ball-end milling forces are investigated by the unified mechanics of cutting approach and finite element (FE) model with Lagrangian boundaries of the orthogonal machining process. Two-dimensional FE model of the orthogonal machining operation is prepared to determine milling forces using this predictive approach. Fully coupled thermal-stress simulations are performed to establish the orthogonal machining outcomes in machining of 20NiCrMo5 steel by tungsten carbide tooling. Applying the oblique cutting theory, the orthogonal machining outcomes are carried to helical cutting tool geometry. Based on numerical and analytical solutions, the milling forces are determined for a range of cutting conditions.
