Abstract
Magnesium and its alloys are slowly entering into the field of bio-implants as a substitute to currently used materials because of their mechanical properties and physiological benefits. However, the magnesium alloys corrode much before than the bone is fully healed because of their high corrosion rate in physiological environment of body. In this experiment, AZ31B magnesium alloy has been subjected to turning operation under dry and cryogenic environment. This research is an attempt to study the effects of cutting speed and feed rate on forces, surface roughness, temperature and microstructure. Furthermore, a comparative study is done on the effects of machining environment on these factors. The results show that a combination of high cutting speed and low feed rate with cryogenic environment gives the best surface finish.
