High-Speed Cutting of Synthetic Trabecular Bone—A Combined Experimental–Computational Investigation
نویسندگان
چکیده
Orthopaedic surgical cutting instruments are required to generate sufficient forces penetrate bone tissue while minimising the risk of thermal and mechanical damage surrounding environment. This study presents a combined experimental–computational approach determine relationships between key parameters overall performance polyurethane-based synthetic trabecular analogue under orthogonal conditions. An experimental model was developed, whereby an adaptable tool fixture driven by servo-hydraulic uniaxial test machine used carry out tests on Sawbone® analogues. A computational process developed using Abaqus/Explicit, Isotropic Hardening Crushable Foam elastic-plastic capture complex post-yield behaviour bone. It found that lower rake angles resulted in formation larger discontinuous chips higher forces, tended lead more continuous chip forces. The modelling framework provided captured features both axial over wide range when compared with observations. experimentally based for analogues has potential be applied three-dimensional processes future.

متن کاملMechanics of high speed cutting with curvilinear edge tools
High speed cutting is advantageous due to the reduced forces and power, increased energy savings, and overall improved productivity for discrete-part metal manufacturing. However, tool edge geometry and combined cutting conditions highly affects the performance of high speed cutting. In this study, mechanics of cutting with curvilinear (round and oval-like) edge preparation tools in the presenc...
