Some clarifications on the mechanics of chip formation when machining titanium alloys

Abstract

Abstract With the increasing need to use titanium alloys for aerospace structural applications and because of the difficulties experienced in machining them (except at low speed), an investigation on the fundamental mechanism of chip formation when machining these alloys was undertaken. An attempt is made in this paper to clarify various aspects related to the mechanism of titanium chip formation based on a critical review of the literature and machining studies on a Ti-(6Al-4V) work material at various speeds with the aid of high speed photography and in situ machining experiments inside a scanning electron microscope.
