description abstract | This paper presents a fiveaxis ballend milling force model that is specifically tailored to microscale machining. A composite cutting force is generated by combining two force contributions from a shearing/ploughing slipline (SL) field model and a quasistatic indentation (ID) model. To fully capture the features of microscale fiveaxis machining, a unique chip thickness algorithm based on the velocity kinematics of a ballend mill is proposed. This formulation captures intricate tool trajectories as well as readily allows the integration of runout and elastic recovery effects. A workpiece updating algorithm has also been developed to identify tool–workpiece engagement. As a dual purpose, historical elastic recovery is stored locally on the meshed workpiece surface in vector form so that the directionality of elastic recovery is preserved for future time increments. The model has been validated through a comparison with fiveaxis end mill force data. Simulation results show reasonably accurate replication of end milling cutting forces with minimal experimental data fitting. | |
