Abstract This study employs response surface methodology (RSM) to model and analyze the effects of abrasive waterjet (AWJ) and CO2 laser cutting on the surface roughness of ARMOX 500 T armor-grade steel (7. 6 mm thick). A comprehensive investigation was conducted to evaluate the influence of key AWJ process parameters. including cutting speed. https://www.ashleyshomestores.shop/product-category/twin-full-bunk-bed/
