    The process carried out in the absence of CLFs is called dry machining (DM), or neardry machining (NDM) when the process runs in the presence of a very small quantity of lubricants, in the range of 10–150 ml h −1, delivered in the cutting zone in a mist way. Thus, the use of NDM (called also minimal quantity lubrication or MQL) can lead to a significant cost reduction for the process.
