摘要: 目的：通过钻削高强度钢的仿真和试验分析，研究钻削加工参数对切削力及扭矩的影响规律，为提高钻削工件质量及效率提供理论研究基础。方法：利用有限元分析软件，建立了3D钻削模型，采用单因素控制变量法，计算分析得到不同工艺参数下钻削轴向力和转矩的变化规律。采用正交试验设计法，应用Kistler三向动态压电式平板测力仪和动态信号采集系统，以及DynoWare软件进行分析和处理，得到不同工艺参数下钻削轴向力和转矩的变化规律。结论：钻削加工仿真分析和试验结果一致表明，切削力随切削速度的增大而增大，扭矩随切削速度的增大而减小；切削力和扭矩都随进给量的增大而增大；切削力和扭矩都随钻头直径的增大而增大。
Abstract: Purpose: Through the simulation and test analysis of drilling high strength steel, cutting regimes are studied quantitatively for the influence law of cutting force and torque, to improve the quality of the workpiece life and processing efficiency to provide a theoretical basis. Means: Finite element analysis software is used for simulation analysis; a 3D drilling model is established; single factor control variable method is adopted. Then, the change rules of axial force and torque of drilling under different cutting regimes are obtained by calculation and analysis. The orthogonal experiment design is used in the experimental study. Relevant data of axial force and torque are obtained by means of Kistler three-way dynamic piezoelectric plate dynamometer and DynoWare software. Then, the change rules of axial force and torque of drilling under different cutting regimes are obtained by calculation and analysis. Conclusion: The simulation results of drilling are consistent with the cutting experimental results; the cutting force increases with the increase of the cutting speed; torque decreases with the increase of cutting speed; both cutting force and torque increase with the increase of feed; the cutting force and torque increase with the increase of bit diameter.
