摘　　要：为研究不同截形麻花钻切削不同材料的钻削工艺性,根据麻花钻的实际生产过程,利用UG软件在麻花钻螺旋线法平面内,以一段或多段相切圆弧代替螺旋槽的法平面截形生成前刀面,并建立了螺旋槽径向截形的数学模型。基于锥面刃磨法的原理分别建立了一圆弧、两圆弧及三圆弧3种不同截形的麻花钻模型。采用DEFORM-3D软件对不同截形麻花钻切削45钢、不锈钢、钛合金3种不同材料的钻削加工过程进行了仿真,并以轴向力及扭矩作为钻削性能指标,对比分析,为后续实际钻削加工中选择合理截形麻花钻切削不同材料提供了参考依据。In order to study the cutting process of different truncated twist drills,according to the actual production process of twist drill,UG software is used to replace the cut shape of the twist drill in the plane of the twist drill.The mathematical model of radial groove truncation of spiral groove is established.Based on the principle of conical grinding method,a twist drill model with three arcs,two arcs and three arcs are established.By using DEFORM-3D software,The drilling process of four kinds of different materials of 45 steel,stainless steel and titanium alloy is simulated,and the axial force and torque are used as the drilling performance index.The comparative analysis is used to select the reasonable cutting shaped twist drill cutting different materials to provide the basis.
