Functionalization of Additive Manufactured Ti Alloy Using Grinding Processes: Achieving Uniform Surface Roughness
摘要
Ti–6Al–4V alloy finds extensive use in medical contexts for bone replacement owing to its favorable mechanical characteristics and compatibility with biological systems. The Ti–6Al–4V alloy produced out of the electron beam melting (EBM) process cannot be used directly for any specific applications. The surface texture needs to be functionalized using various post-processing techniques. In this paper, precision grinding operations are selected as a post processing technique to achieve required high degree of surface finish and tighter surface tolerance for the final component. The influence of processing conditions on the surface including wheel speed, depth of cut, and feed rate on the critical parameters such as grinding force, surface grinding energy, surface roughness, surface morphology, and chip morphology. The effect of these parameters was studied, and some key influencing parameters and their levels were identified for effective processing of this additive manufactured components. The paper specifically focuses on the uniformity of the surface and its influence on the overall surface finish.
