Parametric Analysis for the effect of expansion ratio during Co-Cr stent manufacturing using fiber Laser

Abstract

This research shows how expansion ratio gets affected by the different input parameters of fiber laser. In this research all input parameters were studied and scrutinize the final parameters which affects or influence the mechanical properties of the stent. In this research the input parameters were selected after performing pilot experiments. ANOVA  analysis  is used to finding out the percentage contribution of  each factors on expansion ratio. Mathematical model has also been derived for prediction of expansion ratio without performing actual experiments. It is observed less effect of gas pressur, contributed 10.36%, Percentage contribution of laser power is 61.88 % and frequency is contributing 26.64%.Software developed featured with which can predict expansion ratio of stent without performing actual performance.
