THE ROCK PROCESSING SECTOR: PART I: CUTTINGTECHNOLOGY TOOLS, A NEW DIAMOND SEGMENT BANDSAW PART II: STUDY OF CUTTING FORCES

摘要

This article presents the state of the art in cutting procedures used for ornamental stone processing:primarily diamond segment discs, diamond wires and frame saws. In all these, a reduction in cutting thickness has adirect repercussion on profitability. A new tool is presented with a cutting thickness half that of the best achieved inconventional tools: a band saw with welded diamond segments. The first prototypes are built, cutting tests are carriedout and the features of the cut are studied.In the second part, existing studies on measurement of cutting force in conventional tools are reviewed and theprototype band saw machine is monitored. Cutting forces in this new process are studied, with measurement oftangential force and feed force under various working conditions.
