摘 要: 群钻钻尖用于不锈钢钻削,有较好的排屑性能,但是难于实现三段切屑分别断屑。通过实验研究发现:选用合理的切削刃几何参数,充分利用各段切屑之间的相互作用力,可以显著提高断屑效果,从而延长刀具寿命,提高效率。本文介绍试验过程、结果以及对不锈钢钻削断屑机理的进一步认识。 Multi-facet drill tip is favorable in chip splitting. But it is incapable of breaking the chips split in three segments separately. Experiments exhibit that the chip breaking performance can be elevated by reasonable selecting the drill tip parameters and availing of the interactive forces between the chip segments. Thus, the tool-life and drilling efficiency can be improved. The experiment procedure, results and some insight of the chip breaking mechanism for stainless steel drilling are presented.
