交叉钻孔的加工在进出口处产生毛刺。由于可达性有限，这些相交孔的去毛刺具有挑战性。本文提出了一种适用于球头刀对相交孔进行精密去毛刺的刀具轨迹模型。该模型是借助计算机辅助工程技术开发的。该工具生成与主孔和交叉孔相交几何形状相关的三轴行程路径。毛刺被去除，一个恒定的倒角被加工。相交曲线甚至通过主孔或十字孔加工。采用AlSi7Mg材料对三种不同的交叉试样进行了实验验证。
Machining of cross-drilled holes generates burrs on the entrance and exit. Deburring of these intersecting holes is challenging due to the limited accessibility. This paper presents a model that creates a tool path suitable for precision deburring of intersecting holes with a ball-end cutter. The presented model is developed with the help of Computer-Aided-Engineering. The tool generates a three-axis travel path related to the intersection geometry of the main and cross hole. The burr is removed and a constant chamfer is machined. The intersection curve is even machined through the main or cross bore. The presented model is verified by means of experiments with three different intersection samples using the material AlSi7Mg.
