Machinability Of Al2024, Al6061, And Al5083 Alloys Using Multi-Hole Simultaneous Drilling Approach, Muhammad Aamir, Majid Tolouei-Rad, Khaled Giasin, Ana Vafadar
Research outputs 2014 to 2021
Aluminium alloys are extensively used in different industries due to their good mechanical properties, machinability, low cost and reliable inspection. Drilling is one of the most important machining processes for assembly operations. The number of holes required in an assembly may vary from several holes to millions depending on the application which increases the manufacturing time and costs. In this study, a multi-spindle drill head also known as the poly-drill head is used to perform multi-hole simultaneous drilling with the aim to increase productivity. Dry drilling tests are performed on Al2024, Al6061, and Al5083 aluminium alloys using uncoated carbide …

Despite the growth of composites and other lightweight materials, aluminium alloys remain an attractive choice of the aerospace industry due to their mature manufacturing processes, good resistance to fatigue crack growth and superior damage tolerance. In the aerospace industry, the drilling process is the most challenging among all the other machining process as millions of holes are required for producing riveted and bolted joints in the assembly operation of the aircraft's structures. The major challenges which arise from the drilling of these alloys are characterized by the poor hole quality which might initiate cracks within the airframe structure and reduces …
