|Abstract: ||Bone drilling is widely used in orthopaedics and surgery; it is a technically demanding surgical procedure.
Recent technological improvements in this area are focused on efforts to reduce forces in bone drilling.
This study focuses on forces and a torque required for conventional and ultrasonically-assisted tool penetration
into fresh bovine cortical bone. Drilling tests were performed with two drilling techniques, and
the influence of drilling speed, feed rate and parameters of ultrasonic vibration on the forces and torque
was studied. Ultrasonically-assisted drilling (UAD) was found to reduce a drilling thrust force and torque
compared to conventional drilling (CD). The mechanism behind lower levels of forces and torque was
explored, using high-speed filming of a drill–bone interaction zone, and was linked to the chip shape
and character of its formation. It is expected that UAD will produce holes with minimal effort and avoid
unnecessary damage and accompanying pain during the incision.|
