drilling effect

drilling effect

The linear, “one-dimensional” laceration that occurs with any penetrating object, especially a projectile/bullet from a firearm. Drilling effect is the primary mechanism of injury in low-velocity gunshot wounds, as the kinetic energy is insufficient to create the temporary cavity that is seen in high-velocity projectiles.

The impact rotary sealing device and different bit types were designed considering that the water was hard to seal and to obtain the best rock drilling effect assisted with water jet, which can realize axial and rotational movement simultaneously to explore the impact drilling effect assisted with high-pressure water jet, and to provide scientific basis for improving the efficiency of rock breaking as well as providing reference for improving the reliability and service life of rock drill.
Additional vibrational pulse can effectively improve the drilling effect and reduce the cutting heat in the drilling process [19].
With this knowledge trochoid editing or helical drilling effects could be implemented in a similar high frequency environment.
