Abstract

Titanium and its alloy have wider application prospects in such engineering fields as aerospace and nuclear energy. Presently, most of the ordinary cutting tools couldn't meet the requirement when machining those materials, even if cubic boron nitride and precision ceramics tools as their limitation of physics performance. But natural single crystal diamond tool can be applied to lens manufacture with high accuracy and surface quality as its sharp enough knife-edge used to extremely shin cutting. However, its easily wearing disadvantage limits its application to Titanium and its alloy machining. Ultrasonic vibration is applied to diamond turning of Titanium and its alloy to decrease diamond tool wear and improve the surface quality of work-piece. Under given experimental conditions, when cutting distance is less than 2000 meters, the work-piece surface roughness(Ra) is lower than 0.25μm and the wear width of rear sides of cutting tools less than 8μm. If increasing the amplitude, surface quality of titanium alloy will be improved a lot. With amplitude increasing, diamond tools wear alleviates obviously. Experiment reveals that the effect of cutting depth on surface roughness is distinct. Roughness increases with the increase of cutting depth.. The effect of feed rate on surface roughness(Ra) is obvious. Surface roughness(Ra) increases with the increase of feed rate.
