CUTTING TOOLS (TWIST DRILLS) WEAR EVALUATION VIA TORQUE
monitoring tools condition in real time is of utmost importance in contemporary production systems. The paper presents experimentally established correlations between torque, as a reliable bearer of tool wear information, and influential parameters in drilling steel of high hardness and strength (tempered steel). On the grounds of the established correlations, regression analysis was applied to result in a mathematical model which describes torque as the function of force.
