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