Abstract

In aeronautics, mastering the drilling process is crucial to meet strict quality standards. While robots provide a cost-effective solution for drilling large, complex parts, challenges arise in metallic materials due to their low stiffness. This study establishes a systematic experimental method to improve hole quality during robotic drilling of aluminium alloys. Holes were drilled in plates in four positions and 64 postures using a 6 mm tool to analyse their influence on a new defect index. A static deflection compensation method was developed to improve hole quality, addressing static deflection issues narrowing the gap between robotic drilling and CNC machining.

一种改进铝合金机械钻削的实验方法

在航空领域，掌握钻孔工艺对于满足严格的质量标准至关重要。虽然机器人为大型复杂零件的钻孔提供了经济有效的解决方案，但金属材料由于其低刚度而面临挑战。本研究为提高铝合金机器人钻孔质量建立了系统的实验方法。用6mm的工具在4个位置和64个姿势的钢板上钻孔，分析它们对新缺陷指数的影响。为了提高孔质量，提出了一种静态偏转补偿方法，解决了静态偏转问题，缩小了机器人钻孔与数控加工之间的差距。
