| 针对模具钢切削性能差，严重制约了模具的精密发展和模具钢材料的推广问题，对球头铣刀铣削模具钢的加工过程进行基
础工艺研究。以三维仿真为基础进行SKD61钢铣削力实验。在SKD61钢的三维仿真研究方面，利用球头铣刀进行了曲面铣削有限元仿真，对仿真结果进行分析，
结果表明：SKD61模具钢切屑在切削过程不连续、易断；铣削初始阶段，刃口受到径向冲击影响，铣削力高于稳定铣削阶段。研究发现不同的工艺参数对铣刀刃
口应力的影响有差异，其中每齿进给量的影响较为关键。 |

| 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. |
