摘　　要：利用Pro/E创建了多刃错齿BTA刀具模型,并采用DEFORM-3D大型商业有限元分析软件对钻削过程进行仿真模拟,模拟分析了钻削过程中BTA钻刀齿温度变化及温度场分布情况。通过数码显微系统实施观察,得到各切削刃的磨损状况。为提高钻削加工质量和完善刀具制作工艺提供了重要的指导意义。Multi-blade BTA cutter model is created finite element analysis software is used for the by Pro/E.DEFORM-3D as a large commercial drilling process simulation. Then it analysies the temperature changes and distribution on the BTA cutter of the drilling process.The wear conditions of different cutting edge are got through the observation of guiding significance for improving drilling quality and tool digital microscope. It provides an important making process.
