摘要：高强度钢在切削加工过程中会出现断屑困难、切削温度高和单位面积上切削力大等问题，利用传统的切削试验方法耗时耗财，效率不高且对切削的预见性不强。针对以上问题，利用DEFORM-3D对钻削过程进行加工仿真，分析了仿真过程中遇到的问题并提出了相应解决方法，得到钻削高强度钢时在不同进给量下的轴向力、转矩以及钻削温度等形象直观的仿真结果。在单因素仿真分析的基础上，将不同进给量下的受力情况与经验值计算的力值进行对比分析，得出的钻削中的载荷数值接近理论计算值，为工艺人员研究高强度钢钻削过程提供了有价值的参考依据。

Abstract:High strength steel in the drilling process will appear some problems like chip breaking difficulties，high cutting temperature，the cutting force per unit area is too high and some other issues，using traditional cutting test methods not only spend more time and money，but also the efficiency is not high，and the predictability of cutting is not strong.In view of the problems encountered in the drilling process of high strength steel，the paper simulates the drilling process with DEFORM-3D，analyzed the corresponding problems then proposed solutions in the simulation process，obtain the visual simulation results of drilling，such as axial force，torque，drilling temperature and so on.Based on the analysis of single factor simulation，compared and analyzed the force situation of different feed rate and the force value calculated by empirical value，and the value of load in drilling is close to the theoretical calculation value，which provides valuable reference basis for the process personnel to study high strength steel drilling process.
