Machinability Index Evaluation: A Case Study of Carbide Inserts

Abstract:

The selection of carbide insert on the basis of performance measuring parameters is amulti-attribute decision making problem. This proposed work demonstrates a methodology to evaluate the machinability of the selected turning operation by using graph theory and matrix methods. The qualitative values of attributes are obtained by measuring the process attributes. The fuzzy score has been used to convert intangible factors to crisp scores and then graph theoretic approach has been applied to calculate the single numerical machinability index for ranking among the insert alternatives. Permanent function matrix has been solved by using computer software. This study, in particular, shows the potentiality of graph theory and matrix approach for the analysis, evaluation and selection of carbide insert for machining process. A hybrid decision making method of graph theory and matrix approach (GTMA) and analytical hierarchy process (AHP) is proposed to solve multi decision making problem. The result of study highlights the ranking of inserts based upon machinability index.
