Abstract

A wear-mechanism map describing the wear behavior of the flank of an uncoated high-speed steel (HSS) tool in drilling a die-cast aluminum alloy AlSi9Cu3 was established by plotting the feed rate versus the cutting speed and normalizing the wear rates into dimensionless data points. Several regions in the map are divided in terms of wear rate and wear mechanism together with SEM observation of the worn tool surface morphologies. It was found that the flank of the tool is characterized by adhesive wear, adhesive and abrasive wear, abrasive wear, severely plastic deformation wear and thermal wear according to the wear mechanism. There is a minor wear region called safety cutting zone, where the flank of the tool is characterized by adhesive wear. It is recommended that the HSS tool should work in this region so as to reach long enough service life.
