Background:

Bone drilling is a critical procedure in orthopedics, traumatology, and bone biopsies.
Precise control of drilling forces and torque is essential for successful bone drilling operations.

Purpose of the Study:

To investigate and compare the drilling forces, torque, and overall process between automatic and manual bone drilling techniques.
To analyze the influence of drilling parameters (speed, feed rate, drill bit diameter) on bone drilling mechanics.

Main Methods:

Experimental study using a specialized drilling system to measure forces and torque during bovine cortical bone drilling.
Comparison of automatic drilling versus manual drilling under varying drilling conditions.
Validation of experimental results against established mathematical expressions.

Main Results:

Automatic drilling demonstrated significant advantages in controlling drilling forces and torque compared to manual drilling.
The deviation between maximum and average forces was substantially lower in automatic drilling (5N) versus manual drilling (25N).
Automatic drilling reduced drilling time by 30-60% and generated less vibration.

Conclusions:

The automatic drilling method offers superior control over drilling forces, torque, and the overall drilling process in bone procedures.
Automated systems enhance efficiency and reduce procedural risks associated with manual bone drilling.
This study validates the effectiveness of automatic drilling for improved outcomes in orthopedic and trauma surgery.
