摘要
麻花钻螺旋槽的形状直接影响其切削性能,轴向力及扭矩是主要的切削性能指标。本实验介绍了3种常用槽型的硬质合金麻花钻切削铸铁、合金钢、不锈钢的轴向力和扭矩测量。实验结果表明,与直线型、凸型槽比较,凹型槽麻花钻对这几种材料的切削性能最好。
Flute profile is of much concern to twist drill performance.Thrust and torque are the primary cutting performance indexes.Experiment of the carbide twist drill with three different kinds of flute profile and work pieces(iron,alloy steel,and stainless steel) were reported.Measurement results of thrust and torque for different materials' drilling show that the concave profile is superior to both convex and linear ones.
