Analysis of Machining Operations of a Femoral Prosthesis Using CAM Applications

The studies of biomaterials machinability applied in the medical field are extensive, however many of these studies use models of regular geometry and use elementary machining operations. In this work, a femoral prosthesis with a complex geometric shape was experimental milled using two different commercial Computer Aided Manufacturing (CAM) applications. The toolpaths defined in both CAM applications were similar and carefully selected according with the femoral prosthesis geometry. Roughing, semi-finishing and finishing passes were applied in this work. The influence of toolpath strategy was studied and predicted results from software’s simulation were compared with milled part.
