Machining of bone: an analysis of cutting force, surface integrity and chip morphology

In orthopedic surgery, a damage bone is removed by method of machining in order to enable implant fixation. This requires high precision tools and techniques to prevent mistakes such as overcut and to avoid injuries to the surrounding tissues. This project involved the turning process where bovine b...
