Abstract

Based on analytical and experimental test methods, an evaluation of coated tools efficiency in milling Ti6Al4V with coated cemented carbide inserts is introduced. The stress-strain curves and the fatigue critical loads of the investigated coating were determined at various temperatures by nanoindentations and impact tests respectively, employing FEM-supported algorithms for results evaluation. The stress and temperature fields in the cutting wedge region were obtained by force measurements and FEM calculations of the milling process at various cutting conditions. A sufficient correlation of the coating’s impact resistance at various temperatures with their cutting performance at corresponding cutting conditions is revealed.
