Evaluating the grinding ratio and surface quality of Ti-6Al-4V under varying grinding pass count and depth of cut

Abstract

Surface finishing of advanced difficult-to-machine materials through grinding is posing a significant challenge to the manufacturing industries. However, one of these materials, Ti-6Al-4V has a significantly high usage in several cutting-edge sectors. Thus, finding optimum grinding conditions for processing of this material becomes critical. Present article represents an experimental investigation dedicated towards analysing the effects of varying grinding pass counts and infeed values on the surface roughness, hardness, visible surface burns and grinding ratio of Ti-6Al-4V applying alumina wheel. Experiments are performed to reveal the trend of the surface properties and hardness of Ti-6Al-4V, ground at 10 μm and 20 μm infeed values with different sets of grinding passes. The results indicate that grinding at 15 pass count under 10 μm and 20 μm infeed values are the ideal set of parameters for the operating ranges considered herein.
