3D Finite Element Modelling of Ti–6Al–4V Using Powder Mixed EDM for Bio-Medical Applications

Because of its low elastic modulus and magnificent biocompatibility, the Ti–6Al–4 V is broadly employed in bio-medical applications. Nonetheless, the traditional machining methods degrade their characteristics due to cutting forces and residual stresses, necessitating the use of non-traditional methods. This chapter discusses the three-dimensional FEM simulation analysis of Ti–6Al–4 V biomaterials in respect of material removal rate (MRR) and temperature distribution utilizing graphite powder mixed electric discharge machining (PMEDM). PMEDM is a hybridized non-traditional EDM method in which powder particles are mixed in dielectric liquid to enhance the surface quality of the machined area as well as the machining performance. The 3D Gaussian heat is utilized as a heat source that produces temperature variations within the material and is inspected to predict the MRR of Ti–6Al–4 V. Following that, the FEM predicted results are validated through experimental findings. The modelling and experimental findings were found to be in good agreement. Also, the crater size and shape obtained with the simulation study exhibit similarity with the experimentally obtained craters. It is concluded that PMEDM can successfully produce micro-components of Ti–6Al–4 V for bio-medical applications.
