The article presents a study on Multi-Criteria Decision-Making (MCDM) in the internal grinding process of SKD11 tool steel. The purpose is to determine the optimal input process parameters for the dressing process in order to minimize surface roughness (SR) and maximize wheel life (Tw). The Simple Additive Weighting (SAW) method was utilized for handling the Multiple Criteria Decision Making (MCDM) task, while the Entropy method was employed to determine the weights of the criteria. The experiment also included the analysis of six input process parameters: coarse dressing depth, coarse dressing passes, fine dressing depth, fine dressing passes, non-feeding dressing, and dressing feed rate. The experiment was carried out using an L16 orthogonal array and the Taguchi method. The durability of the wheel and the roughness of the surface of the specimens were measured and documented for investigate in the MCDM paper. The research findings have identified the optimal dressing options for internal cylindrical grinding.

摘要

The article presents a study on Multi-Criteria Decision-Making (MCDM) in the internal grinding process of SKD11 tool steel. The purpose is to determine the optimal input process parameters for the dressing process in order to minimize surface roughness (SR) and maximize wheel life (Tw). The Simple Additive Weighting (SAW) method was utilized for handling the Multiple Criteria Decision Making (MCDM) task, while the Entropy method was employed to determine the weights of the criteria. The experiment also included the analysis of six input process parameters: coarse dressing depth, coarse dressing passes, fine dressing depth, fine dressing passes, non-feeding dressing, and dressing feed rate. The experiment was carried out using an L16 orthogonal array and the Taguchi method. The durability of the wheel and the roughness of the surface of the specimens were measured and documented for investigate in the MCDM paper. The research findings have identified the optimal dressing options for internal cylindrical grinding.
