1. Significantly Improved Wear Resistance (Increased by ~58.6%) The wear resistance of non-planar PDC is significantly superior to that of flat cutters, showing an average improvement of approximately 58.6%.
Mechanism: The unique structure of non-planar PDC results in a smaller contact area when grinding rock, allowing them to cut into the formation easily. This "sharp" contact generates lower instantaneous grinding heat and prevents the accumulation of rock debris. This ensures good thermal stability for the polycrystalline diamond working layer, effectively extending its service life.

2. Substantially Reduced Grinding Load and Enhanced Rock-Breaking Efficiency (Load Reduced by ~41.9%) Under identical grinding conditions, the grinding load force required for non-planar PDC is reduced by an average of approximately 41.9% compared to flat cutters.
Fundamental Change in Rock-Breaking Mode:
    Traditional Flat Cutters: Primarily rely on shearing force to break rock. This results in the rock being ground into fine particles (a high percentage are finer than 40 mesh), leading to lower rock-breaking efficiency.
    non-planar PDC: Rely on strong point load plowing to cut into the rock. This method produces larger debris particles (a high percentage are large granules between 10–30 mesh), indicating higher efficiency and the ability to penetrate hard rock formations more easily.

3. Superior Fatigue Impact Resistance (Up to ~95.7% Increase) Non-planar structures effectively reduce common drilling failures such as tooth breakage and delamination.
Basic Improvement: When the angle between the cutting edge and the vertical direction is 90°, the fatigue impact resistance of non-planar PDC improves by an average of approximately 51.8% compared to flat cutters.
 Optimized Improvement: By designing the angle between the cutting edge and the vertical direction to be 99°, the impact resistance improves by about 30% compared to the 90° design (while maintaining the same wear resistance and grinding load). Compared to traditional flat cutters, this results in an average increase of approximately 95.7%.

4. Optimized Debris Removal Channels and Anti-Mud Balling Performance Compared to flat cutters (and even superior to standard ridge cutters), multi-ridge cutters (3, 4, and 5 ridges) utilize their curved surfaces to form natural debris removal channels.
Advantage: This design facilitates the evacuation of rock debris and prevents accumulation, significantly improving the compact's anti-mud balling performance. This helps increase the utilization rate of the compacts (allowing for multiple repairs), reduces drilling costs, and solves challenges in drilling deep, complex formations.
Summary: Non-planar compacts transform the rock-breaking mode from "planar shearing" to "point load plowing." This provides decisive performance advantages in resolving issues such as lack of footage (penetration), tooth breakage, and delamination in hard rock layers.
