Abstract

Drilling with standard twist drill bits is the most common method to create cylindrical holes. With the constant development of additive manufacturing technologies and easier access to additive manufacturing equipment, it is now possible to design and fabricate solid tools suitable for various machining applications. Specially designed 3D printed drill bits seem more convenient for standard and nonstandard drilling operations than conventionally made tools. The study described in this article aimed to analyze the performance of a solid twist drill bit made from steel 1.2709 using direct metal laser melting (DMLM), which was compared with that of a drill bit manufactured conventionally. The experiments involved assessing the dimensional and geometric accuracy of the holes made by the two types of drill bits and comparing the forces and torques occurring during the drilling of holes in cast polyamide 6 (PA6).

摘要

使用标准麻花钻头钻孔是制造圆柱孔最常用的方法。随着增材制造技术的不断发展以及增材制造设备的日益普及，现在能够设计和制造适用于各种加工应用的实心刀具。与传统制造的刀具相比，专门设计的3D打印钻头在标准和非标准钻孔操作中似乎更方便。本文所述的研究旨在分析采用直接金属激光熔化（DMLM）工艺由1.2709钢制成的实心麻花钻头的性能，并将其与传统制造的钻头进行比较。实验包括评估两种钻头所钻孔的尺寸和几何精度，以及比较在铸造聚酰胺6（PA6）上钻孔时产生的力和扭矩。
