Multi-Objective Optimization of Cutting Parameters during Laser Cutting of Titanium Alloy Sheet using Hybrid approach of Genetic Algorithm and Multiple Regression Analysis
摘要： Now a day’s advance engineering materials are playing a key role in the field of aeronautics, defense and medical. Titanium and its alloys are one of the advanced engineering materials that have great demand in the various fields of industries due to its greater behavior and better mechanical properties. These applications require precise and better quality cuts which may not be obtained by conventional machining processes due to the unfavourable properties of Ti and its alloys. This problem may be minimized by using laser cutting process. In this study, the Advanced 300 W Nd:YAG Laser cutting system has been applied for the cutting of titanium alloy sheet. The point of current research is to optimize kerf width and kerf deviation, simultaneously during the laser cutting of Titanium alloy sheet (Grade 5).The multiple regression analysis has been applied for developing the second order regression models of kerf width and kerf deviation. The optimization technique genetic algorithm has been applied for the multi-objective optimization of the developed models. The comparison results show an improvement of 29.78% for kerf width and 95% for kerf deviation, respectively. The overall percentage improvement of 27.39% has been found by considering the equal importance of both quality characteristics. The parametric effects on quality characteristic have been also discussed.

A Parametric Study of Kerf Deviation in Fiber Laser Micro Cutting on Ti6Al4V Superalloy
摘要： A distinctive scope in the fabrication of desired products with specific standard has been achieved by the recent advancement in the technology. This available developing technology is able to produce production of various components, structures, shapes etc made of different kind of materials with necessary dimensional and geometrical features. But it is extremely difficult for 50 Watt average power machine to achieve good quality cutting of the metal sheet upto 2 mm thickness. A unique parameter sawing angle acts as a significant use in kerf deviation in cutting titanium alloy sheet (Ti6Al4V) of 1 mm thickness in low power fiber laser beam machining. The present field of study deals with the effect of sawing angle with other process parameters like cutting speed, power setting, duty cycle, and pulse frequency for a titanium alloy metal sheet to reduce kerf deviation where experiments are carried out on the basis of central composite design (CCD) technique of RSM.
