Optimisation of Fiber Laser Cutting of Stainless Steel Using TOPSIS - Shannon Entropy Method
摘要
Fiber laser cutting can be applied to achieve a very precise cut of various material by selecting the appropriate cutting parameters. In this study, the influence of three main cutting parameters including laser power, assist gas pressure and cutting speed on the cut quality performance during laser cutting of stainless steel was analyzed. TOPSIS-Shannon entropy method based on Box- Behnken experimental design was applied to find optimal combination of cutting parameters. The optimal cutting condition was obtained at 1000 W of laser power, 320 mm/s of cutting speed and 1.5 bar of assist gas pressure.
