This paper provides a study on multi-criteria decision-making (MCDM) in the context of grinding SKD11 tool steel using a CBN wheel. The MARCOS approach was employed to address the MCDM problem, while the Entropy method was used to determine the criteria weights. Two criteria, surface roughness (SR) and material removal speed (MRS), were chosen for the problem. Furthermore, a Taguchi approach was employed to conduct an experiment with design L18 (61 + 33). Four input factors were analyzed: the grinding depth aed (mm), the wheel speed Rpm (rpm), the feed rate Fe (mm/min), and the wheel diameter dw (mm). The optimal experimental configuration was determined based on the findings of the study.

摘要

This paper provides a study on multi-criteria decision-making (MCDM) in the context of grinding SKD11 tool steel using a CBN wheel. The MARCOS approach was employed to address the MCDM problem, while the Entropy method was used to determine the criteria weights. Two criteria, surface roughness (SR) and material removal speed (MRS), were chosen for the problem. Furthermore, a Taguchi approach was employed to conduct an experiment with design L18 (61 + 33). Four input factors were analyzed: the grinding depth aed (mm), the wheel speed Rpm (rpm), the feed rate Fe (mm/min), and the wheel diameter dw (mm). The optimal experimental configuration was determined based on the findings of the study.
