Abstract

The University of Cagliari (Italy) has carried out extensive research on the use and application of diamond wire in basalt quarries, with the objective of assessing the effectiveness of sawing. The focus of the research has been on time-measurements, in order to produce better data about sawing speed rather than what has already been highly documented by diamond wire builders. Net, technical, commercial and gross sawing speeds are calculated, explained and assessed in close context with the sawed parts.The paper gives also an overview of many issues occurring during block squaring, by offering an interpretation of their cause.
