Abstract

This study applies the Analytic Hierarchy Process (AHP) to optimize dressing parameters in the surface grinding of SKD11 tool steel. Two key performance criteria surface roughness (Ra) and grinding wheel life (Tw) were simultaneously considered. Based on experimental data from 16 dressing trials, the AHP method was used to calculate composite performance scores and rank configurations. The best combination achieved a balanced trade-off between low Ra and long Tw. The results demonstrate that AHP is an effective tool for multi-criteria decision making in precision grinding.
