Optimization of dressing infeed of alumina wheel for grinding Ti-6Al-4V

Abstract

ABSTRACT In the present experiment study, dressing infeed values of 5, 10, 15, 20, and 25 µm are conceived on alumina wheel using 0.75 carat identical diamond dressers. The surface topologies of the dressed wheels are observed under scanning electron microscope. Differently dressed wheels are subsequently, employed for up-grinding Ti-6Al-4V in dry environment for 20 passes while the grinding infeed is kept constant at 10 µm during each pass. The grinding ratio is evaluated and the typical surface roughness parameters are measured using a mechanical type stylus. Tangential and normal force components are accurately measured with the help of dynamometer while the quality of ground substrate is observed under high resolution microscope. The performances of the differently dressed wheels are evaluated and subsequently, the dressing parameters are optimized based on the results obtained herein.
