Abstract
Wear is an important technical and economic parameter in the assessment of cutting performance of diamond tools. It is influenced by many parameters and, the material hardness of the cut surface is one needs to be examined. The current work presents a study of correlation between the Cerchar hardness index (CHI) of hard granite rocks and wear of diamond wiresaw beads. Further the correlation between CHI and wear of large diameter circular disc cutter segments is investigated. Moreover, the linear least regression models for the dataset is developed to grasp the statistical relationship between rock hardness and diamond tool wear. This work may provide significantly valuable insights to the stone and diamond tool manufacturing industry.
