Predictive milling distortion has been widely used to optimize milling design and process. Inherent strains method (ISM) applies plastic strains calculated from small-scale thermo-mechanical simulations to large-scale models to assess residual deformation in less time. In this paper, ISM is proved feasible in milling process by theoretical and experimental analysis. Moreover, a novel method called inverse identification is proposed to obtain milling inherent strain efficiently. To verify the proposed method, two milling cases are presented to evaluate its accuracy in distortion prediction. In addition, comparisons with the thermo-mechanical model and traditional ISM model indicate that the inversely-identified inherent strains can significantly reduce the simulation time at the premise of similar precision, which is practical to be applied in industrial applications.

“…Similarly, based on the reverse heat conduction method, Han et al [18] obtained heat intensity by thermocouple method embedded. Because of the unsteady milling process, Putz et al [19] calculated the unsteady heat intensity of indexable milling insert through the finite element simulation of the interrupted chip formation process. Considering the influence of processing conditions on heat intensity, Pabst et al [20] established mathematical expressions on the heat intensity of end milling based on a polynomial method for feed per tooth, cutting speed, axial cutting depth, cutting width, edge radius, and rake angle.…”

Modelling methods for the transient temperature field of wear land on the flank of end mills have been proposed to address the challenges of inaccurate prediction in the temperature field of end mills during the high-speed peripheral milling of Ti6Al4V that is a titanium alloy. A transient temperature rise model of wear land on the flank of end mills was constructed under the influence of heat sources in the primary shearing zone (PSZ), rake-chip zone (RCZ), flank-workpiece zone (FWZ), and dissipating heat source. Then the transient temperature field model of wear land on the flank of end mills was constructed. Finally, the transient temperature field model of wear land on the flank of end mills was constructed. Comparison of simulation result and experimental data verified the accuracy of the model. In sum, the proposed model may provide a temperature model support for future studies of flank wear rate in end mill modeling.
