MQL (minimal quantity lubrication) machining produces almost similar cutting performance to conventional flood supply machining while using much less metal working fluid. To take full advantage of MQL machining and expand its applicability, an understanding of its jet orientation is critical. Through computer fluid dynamics (CFD) analysis of MQL flow field surrounding the workpiece and tool, it was found that a zone of negative pressure (ZNP) existed between workpiece and flank tool face in turning and was in favor of coolant particle arriving at tool tip. Cutting force was minimal and discontinuous chip effect was best of all when spraying from principal flank face and at range of target 20mm.
