This work presents a research investigation on multi-criteria decision-making (MCDM) in grinding SKD11 tool steel using a CBN wheel. The Simple Additive Weighting (SAW) technique has been used for addressing the Multiple Criterion Decision Making (MCDM) problem, while the Entropy method was implemented to calculate the weights of the criterion. The challenge was overcome by selecting two criteria: surface roughness (SR) and material removal speed (MRS). In addition, a Taguchi methodology was utilized to carry out an experiment using a design L18 (61 + 33). The analysis focused on four input factors: the dressing depth aed (mm), the wheel speed Rpm (rpm), the feed rate Fe (mm/min), and the wheel diameter dw (mm). The study’s findings were used to determine the most effective experimental setup.

摘要

This work presents a research investigation on multi-criteria decision-making (MCDM) in grinding SKD11 tool steel using a CBN wheel. The Simple Additive Weighting (SAW) technique has been used for addressing the Multiple Criterion Decision Making (MCDM) problem, while the Entropy method was implemented to calculate the weights of the criterion. The challenge was overcome by selecting two criteria: surface roughness (SR) and material removal speed (MRS). In addition, a Taguchi methodology was utilized to carry out an experiment using a design L18 (61 + 33). The analysis focused on four input factors: the dressing depth aed (mm), the wheel speed Rpm (rpm), the feed rate Fe (mm/min), and the wheel diameter dw (mm). The study’s findings were used to determine the most effective experimental setup.
