Abstract
The
mechanical behavior (fatigue strength and stress corrosion resistance)
of Ti-6%Al-4%V is extremely dependant on the surface integrity after
machining [1]. Thus, a promising approach to upgrade the in-service
performance of parts made of this Titanium alloy is the application
of reaming as a final process in holemaking operations because of the
possible improvements in hole quality. However, no research has been
conducted and is reported in the literature on the reaming of Titanium
alloys and even the manufacturers of precision manufacturing tools have
very little experience in machining this type of material. The objective
of this project is to investigate the reaming process of Ti-6Al-4V and
to quantify the improvements in hole quality compared to regular twist
drilling by measuring the following hole characteristics: surface roughness,
diameter deviation, hole circularity, hole taper and exit burr properties
(burr height and thickness).
