Many automotive applications require deep drilling on pressure die-cast parts in Aluminium alloys. Aim of the research was to understand if common cutting practices, usually determined on raw materials, can be successful on semi-manufactured parts as well, having an inhomogeneous microstructure. A specific investigation was carried out on deep drilling of a EN_AB-46000 cylinder block, varying technological parameters (cutting speed, feed, tool, lubrication). Dimensional tolerance and surface roughness were measured and statistically analyzed. The quantitative analysis of the process macroscopic performances was combined with an investigation of microstructural aspects of the material, their effects on chip formation and tool-chip interaction.

Abstract

Many automotive applications require deep drilling on pressure die-cast parts in Aluminium alloys. Aim of the research was to understand if common cutting practices, usually determined on raw materials, can be successful on semi-manufactured parts as well, having an inhomogeneous microstructure. A specific investigation was carried out on deep drilling of a EN_AB-46000 cylinder block, varying technological parameters (cutting speed, feed, tool, lubrication). Dimensional tolerance and surface roughness were measured and statistically analyzed. The quantitative analysis of the process macroscopic performances was combined with an investigation of microstructural aspects of the material, their effects on chip formation and tool-chip interaction.
