摘　　要：以硬质合金螺纹梳刀为研究对象,应用有限元分析软件ABAQUS进行螺纹切削加工的仿真研究,分析刀具刃口钝圆半径对螺纹梳刀加工过程中切削力和切削温度的影响。研究结果表明,刀具切削温度分布主要集中在刀尖部位;随着刀具刃口钝圆半径的增加,切削力呈先增大后减小的变化趋势,而切削温度呈先减小后增大的变化趋势,刃口钝圆半径为0.02 mm时切削温度最低。实验测量结果与仿真模型的预测结果具有较好的一致性。该仿真分析为刀具几何尺寸的设计提供参考。Based on carbide thread chaser , simulation of screw machining using the finite element software ABAQUS was carried out.The influence of the radius of cutting tool edge roundness on cutting force and cutting temperature was analyzed .The simulation results showed that the tool cutting temperature mainly concentrated at the nose of the cutting tool .When the radius of cutting tool edge roundness increases , the cutting force firstly increased and then decreased , nevertheless the cutting temperature goes down and then goes up.When the radius of cutting tool edge roundness is 0.02mm, the cutting temperature is at lowest level .Experimental results and the simulation results have good consistency .The simulation model provides a theoretical foundation for the design of cutting tool geometry.
