Optimization of cutting parameters for CO2 laser beam cutting using variable wiight grey-taguchi method

Carbon Dioxide (CO2) laser beam cutting (LBC) process involves several parameters. These parameters need to be optimized in order to get the best quality output. Researchers had applied various types of optimization methods which are used for single or multi-objectives problems. One of the methods i...
