Abstract
The exit burr formation in drilling of aluminum alloy 319 will be investigated.
Particular attention will be focused on the relation between the exit burr type and size and the
cutting parameters. A wide range of cutting conditions (feed rate and surface speed) will be
tested in order to explore also the unusual and extreme cutting conditions. Data will be
collected and analyzed for the establishment of the Drilling Burr Control Chart. Eventually the
data obtained for aluminum will be compared to the data obtained for stainless steel, low
carbon steel and titanium alloy.
