Zusammenfassung: | Objectives: The precise control of diamond layer chamfer parameters has a complex influence on the comprehensive performance of PDC cutters. This control not only helps to expand ideas in PDC cutter design but also improves the overall efficiency of drilling tools. To fully analyze the effect of diamond layer chamfer parameters on the performance of PDC cutters, this study examined the correlation between the chamfer size and chamfer angle of the diamond layer and the performance of PDC cutters, namely wear resistance, impact toughness, drilling efficiency, and damage forms. It provided a scientific basis for optimizing the structure of PDC cutters to enhance the operational efficiency and reliability of PDC bits under complex geological conditions. Methods: The study combined experimental research and theoretical analysis. Two types of PDC cutters, planar type and micro-arc type, which are widely used in the market at present, were selected as experimental objects. Samples with different chamfer sizes (0.2, |
