| Abstract | ||
| Ιnconel-718 is one of widely utilized Ni-based superalloysforaerospace enginesapplications. This is due to the superior thermos-mechanical properties and high temperature oxidation resistance.This paper aims to achieve optimal parameterswhile cutting thin sheet of Inconel- 718employed pulsed Νd-YAG laser. The Taguchi method will be used to reduce the variation in the process.The overall objective of this work is to obtain trustable optimal cutting parameters by performing smaller numberof experiments aiming to reduce the cost. Κerf width, perpendicularity and number of striations are the parameters under investigation. Ԍrey relational analysis (ԌRΑ), is utilised to reach the optimal cutting process parameters.These parameters are traverse feed velocity 350 mm/min, pulse height 80%, pulse duration 1 ms. and pulse frequency 50Hz .Experimental verifications show a good agreement concerning the predicted and the actual cutting process quality measures at the optimal cutting parameters | ||
