In Vitro Experimental and Numerical Analysis of Forces in Plane Cutting of Cortical Bone

Abstract:

Bone cutting is a well know procedure in orthopedics. Large cutting force causes overstressing of the bone which may result in trauma. Control penetration of the cutting tool into bone tissue is important to avoid unnecessary damage to the bone tissue. The purpose of this study was to measure and predict cutting force using experiments and Finite Element (FE) analysis when a plane cutter passes over the bone surface in the presence of irrigation. The effect of cutting speed, tool rake angle, depth of cut and width of the cutting face on the cutting force was found. The force was found to decrease with increase in rake angle and significantly rise with increase in depth of cut and width of cutting face. The cutting force was found unaffected by the range of cutting speed used in experiment as well as in simulations. The results obtained from this study strongly recommend the use of irrigation to minimize plane cutting force or force arising from similar cutting action for safe and efficient surgical incision in bone.
