Fundamental problems in drilling processes are associated with the unfavorable machining conditions in the tool center and the difficult chip removal. Low frequency vibration assisted drilling (LFVAD), in which the linear tool feed is superimposed with a vibratory motion in feed direction, is a promising process to overcome these problems. Aiming at a systematic analysis of the influence of workpiece material properties, results from LFVAD experiments with Ti6Al4V, AlMgSi0.5 and 42CrMo4 in different heat treatment states are presented. Specifically the dependence of optimal oscillation amplitudes on the workpiece material behavior is analyzed.

工件材料对低频振动辅助钻孔切削性能的影响

钻削过程中的根本性问题与刀具中心的不利加工条件以及难以去除的切屑有关。低频振动辅助钻孔（LFVAD）是克服这些问题的一种有前途的方法，在该技术中，线性刀具进给与进给方向的振动运动叠加在一起。为了对工件材料性能的影响进行系统分析，提出了在不同热处理状态下用Ti6Al4V，AlMgSi0.5和42CrMo4进行LFVAD实验的结果。具体地，分析了最佳振荡幅度对工件材料性能的依赖性。
