Minimum quantity lubrication (MQL) machining is one of the promising solutions to the requirement for reducing cutting fluid consumption. The work here describes MQL machining in a range of lubricant consumption of 2.0-2.355ml/s, which is between 10– 100 times lesser than the consumption usually adopted in industries. MQL machining in this range is called pulse jet coolant delivery system. A specially designed system, the IP MQL, was used for concentrating small amounts of lubricant onto the cutting interface. The performance of concentrated spraying of lubricant in pulse jet coolant delivery system design was simulated and compared with that of current ‘Pulse Jet MQL’ systems. The concentrated spraying of lubricant with a specially designed system was found to be effective in increasing tool life in the pulse jet coolant delivery system range.
