摘要：
The present investigation deals with the modeling and optimization of multiple quality characteristics of kerf geometry during pulsed Nd: YAG laser cutting of nickel based superalloy thin sheet along the straight cut profile. Top kerf deviation and kerf taper are considered as quality characteristics. These laser cut quality characteristics are the functions of four input parameters are namely: lamp current, Pulse duration, Pulse repetition rate and Scanning speed. Box-Behnken design (BBD) based experiments have been conducted to obtain experimental results of cut quality characteristics for the study. The experimental results have been analyzed for developing models and optimizing the responses using response surface methodology (RSM). (c) 2018 Elsevier Ltd. All rights reserved.
