| 摘 要： | 采用ProE和Deform-3D软件分析了影响麻花钻钻411性能关健的几何参数,主要研究麻花钻横刃和顶角对不锈钢钻削过程中切削力、扭矩、刀具磨损的影响.介绍了缩短横刃长度和采用S形横刃螺旋面钻尖对不锈钢钻削力和扭矩的影响.重点分析了顶角影响主切削刃的长度、单位刃长的切削负荷、切削层中切削宽度与切削厚度的比例、切削中轴向力与扭矩、切屑形成与排屑情况.对于在钻削中,如何提高钻头的寿命,提高钻削加工的生产率和孔的加工质量具有重要的指导意义. |

| Abstract: | The key geometrical parameters of twist drills that had a great effect on the drilling performance of stainless steel were studied by ProE and DEFORM-3D softwares.The influence of chisel edge and tip angle of twist drill on the drilling force,torque and tool wear in the drilling process was researched,and meantime the effects were introduced by shortened the chisel edge length or adopted S-shape helical drill points as well.The tip angle of drill bit that affected the main cutting edge length,the cutting lo... |
