| Abstract: | The in-depth and comprehensive understanding of cutting characteristics of cutter is the key basis for optimizing polycrystalline diamond compact (PDC) bit. Under down-hole condition, the rock cutting process of PDC cutter is affected by the adjacent cutters, however which cannot be reflected in rock cutting test with a single PDC cutter. In this paper, a three-cutters rock cutting experimental facility with cutter layout adjustment module is proposed to simulate the cutting process of cutter under the effects of adjacent cutters. The rock cutting experiments are conducted with radial spacing, side rake angle and crown shape as variables, and the rock cutting characteristics of cutter are studied according to experimental data. It is found that, increasing radial spacing increases the rock cutting amount of single cutter, increasing side rake angle decreases the proportion of tangential force used for rock cutting, the tangential force and mechanical specify energy (MSE) of cutter increase with the increase of these two parameters, and the effects of radial spacing are greater than that of side rake angle. The cutting area and cutting arc length increase with the increase of radial spacing, but are little affected by side rake angle. The bit crown shape has a significant effect on the rock cutting condition of PDC cutter, the cutting characteristics of inner cone cutter are significantly different from that of nose cutter. The above work is helpful to deepen the knowledge of PDC bit. [ABSTRACT FROM AUTHOR] |
