Abstract

Optimization of the metal drilling process requires creation of minimum amount
of burrs and uniform appearance of the drilled holes. In this paper, an experimental
investigation was performed on 2 mm sheets of wrought aluminium alloy
Al99.7Mg0.5Cu-H24, using 1.6 and 2 mm diameter drills. Cutting data, clamping
conditions, and drill geometry were varied in order to optimize the process and
reach the desired quality. The results revealed possible reduction of burr occurrence
on both the entry and exit side of the sheet, requiring no additional deburring. The
demand on the uniform appearance of drilled holes was fulfilled as well as high
productivity achieved. Such optimized process results in a noticeable production
cost reduction.
