Factors affecting surface finish when grinding titanium and a titanium alloy (Ti-6Al-4V)

Under conventional grinding conditions redeposition which degrades surface finish occurs when grinding titanium and a titanium alloy (Ti-6Al-4V). To prevent redeposition and hence to obtain optimum surface finish the following grinding conditions are required: a soft grade (H) silicon carbide wheel running at 10 m s^?1, a sulphur-chlorinated cutting oil grinding fluid and a relatively high table speed (0.2 m s^?1), and the wheel should be re-dressed prior to taking the finishing passes (about ten) at a wheel downfeed of 2.5 μm.
