Abstract
Some undesirable phenomena in the machining process include vibrations between the cutting tool and the workpiece as well as tool wear due to the destructive effect of vibrations on the surface quality. In machining of titanium alloys, the deterioration of the surface is more critical due to such properties as low modulus of elasticity, low thermal conductivity, and high chemical reactivity. This study has investigated the effect of vibration and flank wear on the surface topography of Ti6Al4V titanium alloy in the process of dry turning. Variation of induced tangential vibration is conducted by increasing tool overhang and the induced feed vibration is conducted by longitudinal turning of a slender part. The results of the investigation of the effect of vibrations on the surface topography of the workpiece show that the increasing of tangential vibration increases the deterioration of surface topography. In addition, study on the effect of tool wear indicates that vibrations resulting from tool wear increase the irregularities on the topography of the surface. Application of laser profilometry for the evaluation of machined surface textures provides more comprehensive information than the traditional two-dimensional measurement.
