Analysing the life index of diamond cutting tools for marble building stones based on laboratory and field investigations

Abstract Cutting tool wear constitutes one of the principal parameters in processing cost building stone. The life index cutting is obtained by evaluating diamond segments plants and examining main thereof. purpose this study to determine considering physico-mechanical properties marble stones operational parameter speed. To end, a dataset was provided collecting data from eight stone provinces Tehran, Isfahan, Yazd Iran. In regard, number square metres that every can cut during its lifetime defined as (TLI). After required data, SPSS software employed for statistical analysis. results revealed Brazilian tensile strength affects index. Linear non-linear regression analyses were then considered development predictive models TLI based on strength. performance developed subsequently examined using three different criteria: coefficient determination, variance accounted for, root-mean-square error. show model presents very good performance, thus, be herein.
