The automotive sector is demanding lighter components being the combination of different materials as an alternative solution to obtain an optimised performance. However, the machining of parts built on magnesium, Magnesium-Aluminium (Mg-Al) or Magnesium-Sintered (Mg-Sint) steel bases is not quite extended, and the technical and safety limitations associated to it are not well-controlled. The machining of two different materials in a single operation demands to reach a compromise between different cooling-lubricant, machinability and machine-tool requirements. This paper shows advances in the machining of a magnesium alloy and magnesium-based hybrid parts under environmentally friendly strategies using dry and Minimum Quantity Lubrication (MQL) conditions.
