Magnesium alloys are used for structural applications of automobile and aerospace industries because of their lower density. Most of the magnesium-based components are produced by casting, and further machining is required. So, magnesium machining is a topic of interest in many industries. In the present study, the machinability of magnesium RZ5 alloy (Mg-4.25 Zn-0.54 Zr-1.25 Ce) is evaluated with and without the use of cutting fluid. The cutting force and surface roughness significantly affected by the feed rate and depth of cut and minutely effected by the cutting speed of the material. The use of cutting fluid with minimum quantity lubrication reduces the cutting force and increases the surface finish of the material. Due to the high-temperature gradient, smaller size chips were observed during machining with minimum quantity lubrication. The rate of tool wear is also reduced during machining of magnesium RZ5 alloy with minimum quantity lubrication.
