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。 The multi-bladed tooth BTA tool model was created by Pro / E, and the drilling process was simulated by DEFORM-3D large-scale commercial finite element analysis software. The temperature and temperature field distribution of BTA drill teeth during drilling were simulated and analyzed Happening. Observe the digital microscope system to get the wear status of each cutting edge. In order to improve the quality of drilling and improve the tool making process provides an important guiding significance.
