Abstract
Ti-6Al-4V
(Ti-64) has become the focus of many drill performance understanding
experiments with regards to exit burr size and shape. Hole quality studies
such as surface roughness, linearity, hole diameter, and roundness have
traditionally been used to confirm formation modes and add additional
parameters to drill performance ratings. The purpose of this analysis
is to identify the relationship between hole surface roughness, cutting
conditions, and tool geometry for a previous burr formation investigation
in the drilling of Ti-64.
