An Investigation About Utilization of Titanium Attribute In Um |
This paper presents a review on the problems encounteredin machining titanium and application of USM in machining titanium and itsalloys. Experiments have been conducted to assess the effect of threefactors-tool material, grit size of the abrasive slurry and power rating ofultrasonic machine on machining characteristics of titanium (ASTM Grade I)using full factorial approach for design and analysis of experiments. It hasbeen concluded that all factors have significant effect on Material RemovalRate (MRR), Tool Wear Rate (TWR) and surface roughness of the machined surface.Two-way interactions having significant effect on MRR, TWR and surfaceroughness have also been identified using Minitab14 software. The levels foreach factor that contribute the most to the variation in machining performanceof USM of titanium have also been established. It has been concluded thattitanium is fairly machinable with USM process. Moreover, the surface finishobtained is better than many of the other non-traditional processes. In this study, the Chemical-Assisted Ultrasonic Machining(CUSM) method is introduced in order to improve the efficiency of conventionalUSM method. To obtain the chemical effects, a low concentration hydrofluoricacid solution is added to the abrasive slurry with glass as workpiece. Thispaper investigates the effect of different input materials on Material RemovalRate (MRR) and Surface Roughness (Ra) in Chemical assisted Ultrasonic Machining(CUSM) process. The effect of various input parameters on output responses isanalyzed using statistical techniques such as ANOVA. Main effect plots for thesignificant factors and their interactions have been used to determine theoptimal design for output response. Through various experiments and comparisonwith conventional results, the superiority of our novel method is verified.
