Optimization of cut surface quality during CNC Plasma Arc Cutting process

摘要

Optimization of cut surface quality during CNCplasma-arc cutting (PAC) of mild steel plates is presented. Usingdesign of experiments (DOE) the optimum process parameters areestimated. The process parameters tested include cutting speed,cutting height and arc voltage. Analysis of means (ANOM) andanalysis of variances (ANOVA) were used in order for the effect ofeach parameter on the surface quality to be assessed.
