RESUMO

The industry of ornamental and dimension stone can be improved by the global and integrated overview of stone properties and performance machines, equipment and insums. Although with excellent growth in production and exportation and great technological advance, the empirism predominates in the productive process, a practice that might leads to loses, failures of equipment, defects in final product and other problems. Pointing this question are presented and correlated operational parameters of the sawing processes and technological properties of rocks, intending to contribute with the optimization of the productive processes and improve quality of slabs. Three varieties of granites were selected, sampled and subjected to petrographical analysis and rugosity evaluation. For each rock the block cut processes using gang saws was accompanied. The set of laboratorial and processes data was treated statistically and analyzed expecting to evaluate the quality of sawed surface slabs. The results obtained are not conclusive and pointing the necessity of future studies to understanding the effective relations between the petrographical features and processes procedures during block cut step in the dimension stone industry. Is expected this approach resulting in better guides to improve the quality of slabs and minimize loses during the processes.
