Fabrication of µ-channels on pure-ti using USM and optimization of process parameters

Abstract

Today, the appropriate use of precision machining to produce three dimensional miniaturized structures or micro devices is another challenging task. Thus, presently miniaturization has emerged as a thrust area of research. The micro components are normally provided with micro channels which are created by using micro tools with the help of nonconventional machining processes. The aim of this paper is to examine machining performance of making micro channels in pure-Ti using ultrasonic machining. The effect of abrasive type, power rating, slurry concentration, feed rate and abrasive size has been investigated on responses namely metal removal rate (MRR) and surface roughness (SR). Taguchi based L18 (mixed level) orthogonal array is selected for the planning of experiments. Finally, the validation experiments have been performed at suggested optimal settings for result reproducibility.
