Abstract
This paper presents the results of a multi-criteria decision-making (MCDM) study in cylindrical external grinding SKD11 tool steel. The goal of this research is to find the best input process parameters for dressing process in external grinding to achieve minimal surface roughness (RS) and maximum wheel life (T). First, the EDAS (Evaluation based on Distance from Average Solution) method was used to solve the MCDM problem and the Entropy method was employed to calculate the weights of criteria. Furthermore, an experiment was conducted with six input parameters: fine dressing depth, fine dressing passes, coarse dressing depth, coarse dressing passes, non-feeding dressing, and dressing feed rate. The experiment was also designed using the Taguchi method and an L16 orthogonal array. Based on the results of the work, the best dressing mode for external cylindrical grinding has been proposed.
