Sensitivity Analysis of Cryogenic Cooling on Machining of Magnesium Alloy AZ31B-O
TypeCommunications avec actes
Improving the corrosion resistance of magnesium alloys has gained special focus in recent years, and cryogenic machining has been one of the successfully used techniques. The current study presents a sensitivity analysis of cryogenic cooling effects on process mechanics, when cutting AZ31B-O magnesium alloy. Finite element modelling was used to simulate orthogonal cutting of AZ31B-O under dry and cryogenic conditions, where different parameters (cutting forces, temperatures, shear angle, chip compression ratio and plastic deformation) were investigated. Also, orthogonal cutting tests were performed on a CNC lathe, under dry and cryogenic conditions, where cryogenic cooling was applied to the clearance side using an LN2 jet.
