This phenomenon has been<br />investigated since the beginning of stone machining, but there are still several open questions<br />concerning the parameters controlling it. The aim of this study is to establish correlations between<br />the natural stone mineralogical composition and the diamond wires cut performance in terms of<br />efficiency, productivity and diamond beads consumption. This investigation requires a<br />multidisciplinary approach. Microscopic analysis have been done in order to investigate the wear<br />processes of the diamond beads in terms of super-abrasive grains (diamond grits) damage and<br />pull out. Petrographic analysis and mineralogical investigation have been considered in order to<br />correlate the removal rate during the cutting action with the characteristics of the stones. Muds<br />derived from cutting have been characterized for the complete comprehension of the cutting<br />process. The erosion analysis concerned both stone debris and diamond beads, characterizing<br />both the metal powder and super-abrasive grains (diamond) in the cut waste (mud). Moreover, the<br />metal matrix is the core of the diamond wire technology and it drives cutting performance and<br />efficiency. ER -
