Abstract
This article takes common material Cr12MoV for automobile panel die as research object, aiming at difficulties when tool cutting in workpiece which are caused by high material hardness in maching, based on simulation software DEFORM-3D, a high precision simulation model of cut-in process in hard milling die steel is established, and the accuracy of the model is verified by tests, the milling force cut-in process in hard milling die steel is studied, the influence law of different cutting parameters and cut-in angles on milling force in milling cutter cutting in workpiece is analyzed, and the optimized cut-in angles are obtained, this study provides a reference for further optimization of cut-in conditions, reducing tool early damage and improving processing efficiency.
