本文利用计算流体力学(CFD)对攻丝过程中的冷却剂流动进行了分析和控制修正。首先，对一种常用的直槽攻丝刀具进行了分析，CFD模拟结果表明，刀具刃口上的冷却液供给不足。因此，基于这些模拟结果，对内冷却剂通道的设计进行了修改。为了验证CFD模拟的有效性，使用优化工具进行了实验测试。经改进后，刀具磨损减轻，刀具性能提高约36%。(C)2017年，由爱思唯尔有限公司代表CIRP发布。
This paper presents the analysis and controlled modification of the coolant flow in tapping processes by means of Computational Fluid Dynamics (CFD). First, a conventional straight flute tapping tool was analyzed and the results of the CFD simulation show, that the cutting edges are not sufficiently supplied with coolant. Therefore, the design of the internal coolant channels was modified based on these simulation results. To validate the CFD simulation, experimental tests were performed, using an optimized tool. The applied modifications lead to a reduction of the tool wear and an increase of the tool's performance of about 36% was achieved. (C) 2017 Published by Elsevier Ltd on behalf of CIRP.
