球头铣刀铣削SKD61钢三维仿真研究
Research on Three-Dimensional Simulation of SKD61 Steel Milling with Ball -End Cutter
摘要
Abstract
In view of the poor cutting performance of die steel,the precision development of mold and the promotion of mold steel materials are seriously restricted.The basic process research was carried out on the machining process of ball-end milling cutter die steel.The SKD61 steel milling force experiment was carried out based on three -dimensional simulation.In the 3D simulation of SKD61 steel, the finite element simulation of surface milling was carried out with ball end mill, the simulation results were analyzed and found: SKD61 die steel chip in the cutting process is discontinuous and easy to break;in the initial stage of milling,the edge is affected by the radial impact,and the milling force is higher than the stable milling stage.The results of stress simulation show that the influence of different process parameters on the stress of milling cutter is different,and the influence of feed per tooth is more important.关键词
