“…For all three force components, it was feed which is the most influential factor. This trend is also reported previously, 18 and it was suggested that since the increase in feed widens the chip cross section, more force shall be required for chip formation. …”

Minimum quantity lubrication is a technique to have the advantages that cutting fluids bring yet keeping their use at minimum. For the cutting fluids, inedible vegetable oils are potential for minimum quantity lubrication machining. Castor oil was selected in this study as the cutting fluid for turning of hardened stainless steel (hardness of 47-48 HRC). The hard turning was with minimum quantity lubrication (50 mL/h flow rate and 5 bar air pressure) at various cutting speeds (100, 135, and 170 m/min) and feeds (0.16, 0.20, and 0.24 mm/rev). The machining responses were tool life, surface roughness, and cutting forces. Design of experiments was applied to quantify the effects of cutting parameters to the machining responses. Empirical models for tool life, surface roughness, and cutting forces were developed within the range of cutting parameters selected. All machining responses are significantly influenced by the cutting speed and feed. Tool life is inversely proportional to cutting speed and feed. Surface roughness is inversely proportional to cutting speed yet is proportional to feed. Cutting forces are more influenced by feed than by cutting speed. A combination of low cutting speed and feed was the optimum cutting parameters to achieve long tool life, low surface roughness, and low cutting forces.

“…In another study on hard turning of AISI 4340 with minimal fluid application, Kumar and Ramamoorthy, 2007 evaluated the performance of two nitride-coated tools (TiCN and ZrN) in terms of cutting force, surface roughness and cutting temperature using statistical design of experiments. Exit pressure was the most significant parameter affecting the cutting force followed by depth of cut and feed whereas type of coating has not much influence.…”

“…They have investigated the effect of nozzle direction, nozzle distance, cutting oil low rate, and cutting time by studying tool lank wear and work-piece surface roughness. According to [18] as stated by [15], the cutting forces reduces with increasing nozzle pressure. Further, according to (Lutao et al, 2012), the low rate of the aerosol does not in luence the surface roughness and tool wear signi icantly.…”

“…Another study carried out using MQL method in machining Aluminium found that, presence of Oxygen in the ambient has caused Aluminium to oxidise [28] which is contradictory to indings of many other researchers. [18] have carried out an investigation on AISI 4340 with coated carbide tool, and concluded that MQL parameters such as, nozzle pressure, aerosol pulsation rate, etc. are in luential heavily on cutting performances.…”

Keywords AbstractCutting luid Machining MQL Tool steels Received: 8 January 2018Accepted: 31 January 2018 Published: 13 February 2018This study is focused on evaluating newly developed chilled-emulsion Minimum Quantity Lubrication (MQL) method on machining hard-to-cut metals. Previous research work revealed that, aerosol at 15 0 C provides the optimal tool life and generates the least surface roughness when machining AISI P20 and D2 tool steels at a given cutting speed. In that context, the in luence of varying cutting speeds with MQL aerosol at 15 0 C is further studied in this paper. Three cutting speeds were used as per the tool manufacturer's recommendations. For the aforementioned cutting conditions, tool nose wear were measured and topologies of worn cutting edges were observed and compared. The experimental results revealed that tool wear rate and other forms of damages such as chipping and plastic deformation for different work material have contrasting responses. This indicates that MQL aerosol performance is notably sensitive to work material properties and its bene its as a cutting luid should be further investigated over wider range of materials.
