Abstract
This paper deals with an experimental study of ultra-precision diamond cutting of magnesium alloys. In order to investigate the cutting performance on the surface integrity and understand the problems on the generation of the good mirror surface in a micro cutting, the experiments on the diamond cutting of magnesium alloys and pure magnesium with an ultra-precision turning machine has been carried out The surface integrity of finished surface of magnesium alloys was mainly examined and discussed the effect of inclusion and intermetallic compound in the micro structure. It was found that the inclusions (Al-Mn compounds) in the work material (AZ31,AZ61) caused to generate the scratches on the finished surface of pure magnesium and AZ91 (cast plate).
