Machining of Magnesium and Magnesium Alloys
Magnesium is machined in low-volume production on small, manually operated machine tools and on large, specially built, completely automated transfer machines operating at high production rates. This article focuses on the factors that affect the machining of magnesium. It discusses chip formation and distortion due to thermal expansion, cold work, and clamping and provides information on magnesium-matrix composites. The article describes materials, design, and sharpness as factors for selection of tool for machining magnesium. It illustrates turning and boring, planing and shaping, broaching, drilling, reaming, counterboring, milling, sawing, and grinding operations performed on magnesium. Safety measures related to machining, handling of chips and fines, and fire extinguishing are also discussed.
