Minimum Quantity Lubrication (MQL)- A Step to Understanding of the Process

Paper in proceeding, 2006

This paper deals with the results which were obtained at cutting with different lubrication media such as; Minimum Quantity Lubrication (MQL), compressed air and emulsion. The results are compared with dry cutting in terms of chip contact, tool wear and temperature effect. The face turning tests showed that MQL changes the friction in the sliding region and this change affects the tool wear both on the primary and secondary cutting edge. The temperature measurements with special inserts have shown that, the lowest temperature is obtained when using conventional cooling media followed by MQL, compressed air and dry machining.
